Glass Manufacturers’ Marks noticed on bottles, fruit jars, tableware and other sorts of glassware ~   Note: for introductory and explanatory feedback and dialogue regarding this segment of the site, please click on on the “A-B” hyperlink below which points to “web page one”.   Thank you!

M………………………… the backside of cobalt blue jars and bottles, normally Maryland Glass Corporation, Baltimore, Maryland (1907-c.1970s).   Exact period of use is uncertain, but verified on the base of cobalt “Milk of Magnesia” bottle from circa 1950.  Most Maryland Glass bottles, if they bring a mark, have the “turned around M” on the base.  (Please see next entry). If a bottle with a “undeniable M” is some form of drugs bottle and was made in cobalt blue coloured glass, it's most likely a made of Maryland Glass.    Also, a similar mark is seen on the base of certain mouth-blown amber, aqua and clear beer bottles (and a smooth-lip amber salve or chilly cream jar) that seem so far c. 1880-1905, and the glassmaker in those cases predates Maryland Glass and to my wisdom stays unidentified.  (For example, some beer bottles marked “F. & P. BOCHART, NEW ALBANY, IND” are marked with a undeniable “M” on the backside, and the ones would date someday between 1890 and 1907, judging from the years that bottler was once in business).  The unknown (unidentified) glass manufacturer used to be most likely located someplace in the Midwest, i.e.  IL, IN, OH or PA.  There were quite a lot of bottle factories simply in those states with a name starting with “M”, which shows why it is so onerous to know for certain who the maker of the ones bottles used to be.    NOTE:  In some instances a “simple M” is also the mark of the  Mosser Glass Company, Cambridge, Ohio  (1971-to date)  but in those circumstances, understand that Mosser produces upscale decorative and novelty glassware, now not utilitarian bins.    See “M inside a circle” and “M inside a G” entries, as well as next access. M (on the bottoms of intricately designed, hand decorated milk glass wardrobe set items, similar to shallow ring trays and glove trays)…………. nearly certainly  James J. Murray & Company (Murray Flint Glass Works), Philadelphia, PA (c.1891 or previous – c.1922 or later?).  This glass maker, positioned at the corner of Culvert Street & Trenton Avenue south of Waterloo Street, specialized in lamp globes, sunglasses and different lighting fixtures fixture-related glassware in addition to novelty pieces. This company would possibly have expanded to transform a distributor of a greater diversity of goods for division retail outlets in later years (?)  Here is a hyperlink to a fire insurance map from 1894:

Here, as embossed on the base of a small cobalt blue Bromo-Seltzer bottle. M inside of a circle (on the bottom of glass packing containers, especially medication bottles of many sorts and sizes, ceaselessly in cobalt blue glass) – see more information about this mark on this webpage……….. Maryland Glass Corporation, Baltimore, Maryland (1907-c.Seventies). M inside of a circle (on tableware, novelty glass, salt dips, glass sneakers, children’s mugs, ornamental toothpick holders and lots of different sorts of reproduction coloured glassware, normally not on utilitarian/commercial  packing containers)………………………….. Mosser Glass Company, Cambridge, Ohio (1971-to date). NOTE: the “M” may or would possibly not have moderately angled vertical strokes in order that the letter seems to be an upside-down “W“.  Also please see “M” and “M inside define of the state of Ohio” entries, as well as the “M inside of a circle” entry concerning Maryland Glass Corporation.

Mosser Glass Company – “M within a circle” mark on the base of ruby pink toothpick holder/votive candleholder.

M inside of a G…………Maryland Glass Corporation, Baltimore, Maryland (1907-c. Seventies).  This mark is showed to exist on the base of a cobalt blue oblong “2 ounces” marked bottle, with vertical ribbing on the entrance; most definitely an iodine or poison bottle.  Also noticed on the base of  a cobalt “Perfection Ginger Ale, Brooklandwood Springs  Company, Baltimore, MD” bottle. (Thanks to Ken Previtali for the guidelines on the ginger ale bottle!)  The “G” is very equivalent in appearance to a horizontally oriented oval.  Because of its presence at the Brooklandwood Springs bottle, I imagine this to be virtual proof that this actual mark used to be certainly used by Maryland, even if only in rare cases as in comparison to their “M inside of a circle” mark which was once in most cases used. M inside a diamond, noticed on druggist bottles and glass eye wash cups……………. John M. Maris Company, wholesalers/jobbers of druggist ware, sundries, pharmacy “furniture”— this company started in 1842 as Pleasants & Maris, title modified in 1846, industry workplaces in Philadelphia and New York City.  Still in trade (2015) with workplaces currently primarily based in Rockaway, New Jersey. John M. Maris Co. offered medication wholesale till 1872 once they changed the point of interest moderately and began promoting a large line of glass druggist bottles and connected ware (Pharmaceutical Era, Vol. 39, pge. 166, 1908). Apparently most (if now not all) of the glass offered by way of Maris was/is in reality manufactured by way of unnamed glass bottle companies, in early years virtually definitely Whitall Tatum & Company of Millville, New Jersey who specialised in druggist ware of all kinds. The “M in a diamond” mark is confirmed on several other glass pieces including a transparent druggist bottle circa 1885; transparent and cobalt blue eyewash cups; and a miniature clear glass mouth-blown lamp with a flooring lip and steel screw-top wick assembly which used to be observed on ebay and said to have in all probability been used for scientific/laboratory functions. Apothecary weights (tokens) are known with the “M within a Diamond” logo. Also, showed as marked at the bottom of a milkglass cold cream jar, circa Twenties-1940s (but this item would possibly or many no longer have any connection with Maris?). Also, please see next access. (Thanks Nona H. for the eyecup, and because of George Sturrock for his help in researching this mark!) M within a diamond (on Mason-type zinc caps for fruit jars, and their corresponding milk glass “discs” or inserts)……….Marion Fruit Jar & Bottle Company, Marion, Indiana – with crops also positioned at Fairmount, IN; Converse, IN and Coffeyville, KS. (1888-1904). “The Marion Jar”, a fruit jar made circa Nineties to 1904,  at the beginning got here with these lids.  The “M” has relatively out-curved “legs” which make the mark seem as the letter “W” when seen the other way up.


M in a hexagon………Metro Glass Bottle Company, Jersey City, New Jersey. Mark used c.1949-c.1981. Also with crops at Washington, PA (since 1957); Carteret, NJ (1958) and Dolton, IL. Known as the Metro Glass Division of National Dairy Products Corp. after 1956 (Kraftco after 1969). Later referred to as MetroPaok Containers. MetroPak was once purchased through Ball Corporation in 1980. The Jersey City plant was closed on Nov. 13, 1981, but the different 3 plants persisted in operation. I’m unsure of the exact chain of later occasions on this corporate. If , email me! M in a keystone……..Metro Glass Bottle Company, Jersey City, New Jersey (Mark used c.1935-1949). See above entry. M in a defend……….Monarch Glass Company, Compton, California (c.Twenties). Seen on base of Puritas water bottle. M inside define of the state of Ohio…………… Mosser Glass Company, Cambridge, Ohio (1971-to date). Seen on colored tableware and upscale novelty glassware. See also “M” and “M in a circle”.

Midland Glass Company mark M (abstract representation), shown, consisting of one stroke, a slim rectangle or horizontal line, positioned over 3 different slender rectangles or vertical strokes (at proper angles). This logo is also supposed as an abstract M, but in addition appears one thing like a capital “E” with a space between the vertical stroke and the three horizontal strokes. Looking at it the other way up, the mark would possibly resemble the Roman numeral “3” with an underline…………………….. Midland Glass Company, Inc., Cliffwood, New Jersey; Terre Haute, Indiana, and Shakopee, Minnesota (1968-1984?) This mark is often seen on “stubby” non-returnable beer bottles of the 1970s. MACE / U.S.A. ……………………. Unknown. This appears, along with a “Crescent Moon” logo which is an unidentified mark, on the base of a transparent pharmacy bottle lettered “Eugene Gosselin / 148 No. Champlain St. / Burlington / VT”. Info in this bottle was once reported by way of Barry Conolly.

MAINE, with number and/or letters & the word “SEAL”,  on milk bottles) ………………………………… a variety of glass producers made milk bottles with this type of marking, required by means of state regulation, for bottles used within the state of Maine.  See checklist at this milk bottle web site (archived snapshot): Mansfield Glass Works……….Mansfield Glass Works, Lockport, New York (1872-c.1909). See Lockport Glass Works entry. MARVEL……………………Unknown. Reported on base of transparent glass pharmaceutical/drugstore bottle. Probably a emblem name utilized by a particular glass producer for his or her line of prescription bottles (corresponding to “LYRIC” through Illinois Glass). MASON’S PATENT NOV 30TH 1858 ………………… Click here for a general abstract of this marking, seen on fruit jars. MASS (with number and/or letters & the word “SEAL”,  on milk bottles) ………………………………… a large number of glass manufacturers made milk bottles with this sort of marking, required through state legislation, for bottles used/distributed throughout the state of Massachusetts.   See this web page for a list of identical marks: MASS GLASS CO. …………….Massachusetts Glass Company, Somerville, Massachusetts (c.1867-1871?) . This producer is assumed to have produced unmarked glass insulators, apparently none of which were yet undoubtedly known (See my page on  Insulator Manufacturers). This rare mark, which is assumed to be connected to that very same corporate, has been reported seen on the base of an overly, very small selection of bottles. M. B. & G.CO………Massillon Bottle & Glass Company, Massillon, Ohio (1900-1904) M.B.W………………Millville Bottle Works, Millville, New Jersey (1903-1926). Bought via T. C. Wheaton Company in 1926. MBW made chemical, druggist and laboratory bottles, glass tubing, funnels, and so on.  Exactly when the “M B W” used to be discontinued in actual apply is unclear, as bottle molds in use on the time of the buyout in 1926 may have endured to hold that mark for just a bit while after 1926, ahead of sooner or later being retooled.   See T.C.W.& CO. McC………………..William McCully and Company, Pittsburgh, Pennsylvania (1841-c.1909)

(Photo courtesy of Jack Klotz). McC & CO……………William McCully and Company, Pittsburgh, Pennsylvania (1841-c.1909) McC & S……………………..Unidentified with simple task.  These initials seem on the base of an American-made aqua 12-sided “umbrella ink” bottle which seems thus far from the overdue 1860s into the early 1870s.  The base is a “key mold” variety with out a pontil mark. This is the one known document of this particular mark that I am aware of.  To my knowledge there is only one transient instance of the firm identify “Wm McCully & Son”,  it appears that evidently from the 1850-1852 timeline as appears to be implied on page 187 of “Allegheny County’s Hundred Years” (1888) via George Henry Thurston.  However,  the bottle on which this mark appears seems to post-date the early 1850s, so at the moment I will be able to’t say needless to say if this would be the right kind attribution?!   If any person else has seen this mark on any bottles, please contact me! M.C.G.CO……………..Unknown. This mark seems on the base of a number of transparent, handmade druggist/prescription bottles. Possibly from an unidentified glass corporate in one of the vital Eastern states, perhaps New Jersey?

Unknown British maker. (Photo courtesy of Natasha Moletta) M C G Y (with faint letters I A)………………Unknown. This mark appears on the base of an excessively dark coloured ale or beer bottle from Great Britain, more than likely circa 1860s-1890s. Similar to the darkish olive inexperienced “black glass”  ale bottles marked “C.W. & CO”. The order of the letters is believed to be as stated, however it is possible the first letter may not be the “M”.  Also, it isn't absolutely transparent if the letters “C” and “G” are accurately recognized, as they seem very equivalent, so the real abbreviation might be “M G G Y” or “M G C Y”.  If somebody in the United Kingdom is aware of the id of this early glass company, please advise! McK in a circle…….. McKee & Company, Jeannette, Pennsylvania (1888-1951). Seen on more than a few items similar to black glass salt shakers and other opaque glass tableware, this mark was once in all probability used most commonly in the Thirties and ’40s. McKee was a subsidiary of Thatcher Glass Manufacturing Company in 1951, and sooner or later the manufacturing unit was once purchased by Jeannette Glass Company in 1961. For some additional info on McKee, click on here. McKee & Co…………..see McKee Glass Company page. McK. G. Co. …………. McKee Glass Company, Jeannette, Pennsylvania.  Seen at the base of syrup dispenser, circa 1951. See  McKee Glass Company  web page. McL………………..McLaughlin Glass Company, Vernon, California (1920-1935).   Especially well known by glass collectors for their electrical insulators, McLaughlin additionally produced all kinds of bottles and different glassware.  Most McLaughlin products are discovered in the Western states of the USA.  For additional information click on right here .  [Note: Some water bottles (and most definitely different varieties of bottles) marked with “McL” on the base additionally date from the 1940s and Nineteen Fifties when William McLaughlin operated different, smaller factories in Vernon and Gardena, California.] McLaughlin (on glass insulators)……………….McLaughlin Glass Company, Vernon, California (1920-1935) M C W …………….Mallinckrodt Chemical Works, St. Louis, Missouri (1867-to date). I believe most, if now not all, of the bottles found with this mark are hand-blown and date from approximately the 1880-1920 duration. The exact glass factory where these bottles were made is unknown, but Illinois Glass Company, Alton, IL, can be a most likely source. Mechanic Glass Works, Philada……………..Mechanic Glass Works, Philadelphia, Pennsylvania. Exact dates of operation currently uncertain, however an excessively scarce flask which bears this inscription appears to this point from sometime within the 1845-1865 period. M. F. J. and B.

It was once previously owned through Saint-Gobain Containers, later Verallia.  If anyone knows what year the MG mark used to be discontinued and when the later marks have been phased in at this manufacturing facility, please contact me! MG (letters connected, as proven at proper)…………………..  Maywood Glass Company, Compton, California (1930-1959).  For more information, please see the  Maywood Glass Company page.  MG mark as embossed at the backside of an amber wine or liquor bottle made by means of Maywood Glass Company.

(Photo courtesy of Abby Chovanec) M. G. W. …………..Massillon Glass Works, Massillon, Ohio (1881-1904). This mark has lengthy been a thriller, with little or no concrete proof available pointing to any specific glassmaker. For a long time, I had posted Middletown Glass Works of Middletown, New York (1887-1891) as a conceivable user of the mark. However, currently it has come to my attention that the Massillon Glass Works, a manufacturing unit which was later extra commonly identified below the firm identify (operating corporate identify) of Reed & Company,(see “R & Co” mark)  is virtually positive to be the true supply of bottles which elevate this mark. Virtually all MGW bottles which also raise brewery or soda bottling firm embossings at the face of the bottle are from cities situated in Ohio (plus a naked handful from southern Michigan). This could be very strong proof for a glass manufacturer from that general subject.  In-depth find out about through archaeologist/author/researcher Bill Lockhart, and, in addition, knowledge submitted by means of Rob Riese, a Massillon-area bottle collector (regarding MGW-marked beer bottles discovered slightly a couple of hundred feet clear of the unique site of the Massillon Glass Works), virtually clinch this id as soon as and for all. Most of the M G W bottles are export beers, of the same normal sort and look of the R&CO beers made by Reed & Company. It may be very conceivable that the MGW mark was used for the primary few years of operation, and later the R&CO mark was once phased in. Furthermore, it is imaginable each marks have been used simultaneously for some time frame.  Thanks to Bill Lockhart and Rob Riese for this update! Michigan Mason (on fruit jars)……………….. Michigan Glass Company, Saginaw, Michigan (1911-1916). MILLVILLE BOTTLE WORKS 1888 …………. lettering on copy (myth) bottle manufactured through T.C. Wheaton Company circa Seventies.

This mark (proven) was reported to me as being observed on restaurant glassware (akin to mugs, tumblers) in Canada.  Recently I won word from Lisa Wallis, who had sent me the image at proper, that this mark was once used by Libbey-St Clair, Inc.  Currently, there seems to be very little information online about that firm, however they have been it seems that in business at least as early as 1979, and most likely into the very early Nineties.

The “P in a flag” mark has now been undoubtedly identified as having been utilized by the Pennsylvania Glass Products Company of Pittsburgh. This data has come to me from Lynor Lisi, who sent pictures appearing lettering on a cardboard carton of unused “NOS” emerald green bottles bearing the “P in flag” mark on their bases. The carton perceived to had been manufactured (or packed) in June of 1971. The bottles were actually manufactured by way of Owens-Illinois at their Fairmont, West Virginia plant. Apparently Pennsylvania Glass Products Co. dispensed vials, medicinal and laboratory bottles on the wholesale level, promoting merchandise in reality made by means of O-I. There are listings on the net that point out PGPC remains to be in industry, but the exact timeline of industrial activity between 1932 and the present is quite murky, and the full duration of use of this mark on bottles is unclear.  PGPC used to be plainly in business (to some capacity) as early as 1932, the president of the company (Tunis J. Dykema) receiving a patent for his invention of a mixture bottle stopper/rubber dropper in that year. The unique patent number is 1843812, the “Re-issue” quantity is #19520 which may also be found on “Google Patents” as RE19520.  That patent number is usually, if not all the time, marked at the base of the bottles in conjunction with the P marking.

(Photo courtesy of Penny Garcia) R inside a “Sun” or Sunburst………….. This mark is noticed on the base of a number of kinds of bottles, together with cylindrical bottles that, judging from the style, most certainly contained ground wax, furniture polish or a equivalent product.  The mark is also noticed on bottles with the accompanying markings “DES PAT” and “94,231”, regarding a bottle design patent that used to be issued to Glenn A. Mengle on January 1, 1935, and assigned to Wizard, Inc, of Chicago, Illinois. Some later bottles indicated they had contained merchandise made / bought via Midway Chemical Company of Chicago.  An oblong bottle containing a emblem of multi-purpose oil  (“Radiant Machine Oil”)  has been recorded, made via Midway Chemical.  The bottle bundle shows the design of the word “Radiant” positioned within a sunburst. These bottles had been made by Owens-Illinois Glass Company and possibly Brockway Glass Company, and possibly date from the 1935 to mid-1950s technology.  Although the Mengle connection is relating to a “patent” of a bottle design, this “R in a sunburst” logo would assumedly be classed as a “trademark“,  of which explicit detailed information has not been found as yet, at least to my knowledge.   It seems that the “R in a sun” has been used as a hallmark on numerous different family/cleaning-related products offered through each Wizard and Midway over time.

This bottle base has 1949 date code to the proper of the logo.R in a triangle……..Reed Glass Company, Rochester, New York (c.1927-1956). The 1927-1956 date vary is given by means of Julian Toulouse in Bottle Makers and their Marks (1971).  However, I won a document from Taylor McBurney who showed this mark on an older, sq. home made bottle (prob. circa 1890-1915) so, assuming Reed was once the maker of that bottle, they it appears used the “R in a triangle” much previous than stated by Toulouse.  The “R in a triangle” on that bottle might also point out every other, unrelated and unidentified company. See “Reed”, Rochester Glass Works, “C-H” mark. R & CO (on the bottom of beer bottles)………………Reed & Company, Massillon, Ohio (1881-1904).   See this page for more information. Randall (some pieces are marked “A. L. RANDALL CO. PRAIRIE VIEW, ILL”) …………. observed at the bases of white milk glass and transparent emerald green glass florist vases and bowls. This seems to had been a company, located in the metro Chicago area, that specialized in selling merchandise for the florist business (together with each glass and ceramic planters) a minimum of for some length of time all over its lifestyles. One reference indicates the corporate used to be in trade for over 100 years, beginning in 1888.  ( ) .  An access on the web site checklist trademarks indicates they implemented for the trademark “RANDALL” in 1991, claiming first use in 1948, but that trademark has since been indexed as “Cancelled”.   Since the Randall corporate was by no means a glass manufacturer, however a distributor/wholesaler, the glass with their company name at the backside was once made via an unidentified glass maker. If you've knowledge on what company (or corporations) in fact made the glass marked “Randall”, please advise!  The glass is the same in “look” to that marked “E. O. Brody” and “Hoosier Glass”, and I think (with no proof) some of it may well be products of Indiana Glass, or Anchor Hocking.   Also, there are difficult to understand references online to a “Randall Glass Company” of Randall, West Virginia in the early 1900s, however that company turns out to have completely no connection to this concern. Rawleigh’s (W.T.Rawleigh’s / Freeport, Ill ) ……………… bottles together with his marking are reasonably often discovered all the way through the United States. Please see this page for more information. Ravenna Glass Works…………Ravenna Glass Works, Ravenna, Ohio (1857-1866). Full title is located embossed at the face of fruit jars and whiskey flasks. Info on precise dates of operation courtesy of Brian Gray. R B (on base of square, heavy handmade green-aqua pickle bottle, Great Britain)…………Unknown. One possibility could be Roberts & Brown, Castleford, Yorkshire, England, a glass bottle maker indexed in a c.1852 checklist of bottle makers in England, however this pickle bottle may date much later.

I’m not sure on years of production, but perhaps 1990s to provide. If you could have more info, please contact me! Reed……………….F.E.Reed Glass Company (or Reed Glass Company), Rochester, New York (c.1899-1956). See Rochester Glass Works. REIP (or R  E  I  P)………………as  noticed on base of crown-top blue-aqua tooled lip “export beer” genre bottle, most certainly made circa 1895-1915.  Unknown. (Reported by Lee Taylor).  Could be either initials, or a real surname for a brewer or bottling company? REX (in cursive script)…………Obear Nester Glass Company, East St.Louis, Illinois (1894-1978).  Mark used from 1896 to circa 1910?. Trademark utilized by Obear-Nester, every so often noticed on base of transparent prescription bottles. Please see “N in a sq.” page. R.G.& B.CO……………Rhodes Glass & Bottle Company, Massillon, Ohio (1901-c.1919). This mark and the following variation is observed rather frequently on bases of amber and aqua beer bottles from towns in OH, PA, IN, MI, WI, and MD that I am aware of, and almost definitely other states as well. An difficult to understand corporate which is nearly unknown to bottle creditors, nevertheless relatively a number of bottles have been manufactured over a duration of virtually two decades. The title of the company seems to have changed relatively at some unknown time all the way through its historical past, with the “&” being neglected. Perhaps long run analysis will shed extra gentle on this company. R.G.B.CO………Same as above. Presumably a variation of the above mark. R.G.CO……………..Root Glass Company, Terre Haute, Indiana (1901-1932). Mark used by Root in the early years (1901-c.1909). Toulouse (Bottle Makers and their Marks, 1971)  stated these initials stood for Renton Glass Company, Renton, Washington (1907-1911). However, the “R.G.CO.” mark which was utilized by Renton most probably seems simplest on certain bottles from the West Coast. I don't believe any of the numerous Midwestern-origin soda and beer bottles observed with the “R.G.CO.” marking originate from Renton.  See Root Glass Company web page. R.G.Co. T (around diamond)………..noticed on base of druggist bottles made in Canada.  Richards Glass Company, Ltd.  (later Richards Packaging), Toronto, Ontario, Canada. (1912- to date).  Richards was/is  a jobber/distributor and did not manufacture their own bottles, but had container ware made for them by way of Dominion Glass Company (D in a diamond) and later through different unidentified glassmakers. See  also RIGO,  R (with bottle-shaped notch), and RP entries. For more detailed information on the Richards’ marks, see this thread at the Antique-Bottles.web web site: Antique-bottles.web discussion thread: Have any of you Canadian creditors noticed this mark?  (Thanks to Glen Phillips and Eric Kloff for their assist and analysis!) R.G.W. ……………..Possibly Ravenna Glass Works, Ravenna, Ohio (1857-1866). Seen on base of wax sealer fruit jars. (Dates courtesy of analysis through Brian Gray). R.I.  (with number or letter and the word “SEAL”, on milk bottles) ……………………………………  a number of glass producers made milk bottles with this kind of marking, required by means of law for bottle used / disbursed within the state of Rhode Island.  See  listing at this milk bottle website (archived and not continue to exist the internet): R.I.B……………..Unknown. (Rhode Island Bottling Company??) Seen on base of beer bottle, this mark could stand for both a brewing corporate, bottling company or a pitcher bottle manufacturer.

RICKETTS & CO GLASS WORKS, BRISTOL ……………………….H.Ricketts & Company Glass Works, Bristol, England.  This embossing is observed, arranged in a circle,  at the backside of early blackglass ale and wine bottles. Bottles with this marking are believed to date from 1821 to about 1853.  This is almost certainly the earliest type of bottle wearing an embossed glass manufacturing unit identification mark at the base. RIGO…………. Richards Glass Company Ltd., later Richards Packaging, Toronto, Ontario, Canada. (1912- thus far) .  As noticed on cobalt blue poison bottles. Bottles if truth be told made by way of Dominion Glass Company. The “RIGO” mark apparently dates from 1912 to (a minimum of) the 1970s. (Also, please see “R.G.Co. T” entry). RM (monogram)………..Unknown. Reported to me as seen on beer or soda bottle base shard. Robinson, Geo. W. (Geo. W. Robinson / NO. 75 / MAIN ST W. VA.)……………………embossed marking on face of strapside flask. Made at the North Wheeling Glass Works (dba Geo. W. Robinson), Wheeling, West Virginia (c. 1860s- c.1910).  Exact time period when these flasks have been made is open to question, however they are going to date from sometime all over the 1865-1875 length. Some resources (i.e. McKearin) point out the works have been in business as early as 1860. But within the earlier years window glass was once the predominate product; later on they switched to making basically bottles.  George W. Robinson was the landlord/supervisor of the works someday within the 1860s/1870s. An 1879 reference (History of the Pan-Handle, published through J. A. Caldwell) mentions “Mr. Robinson” was once fascinated by early years, however signifies the works had only recently began running with a brand new company (crew of homeowners) under the title “North Wheeling Glass Company”, for a “short while”, that means perhaps since 1877 or 1878(?).   The last mention I will in finding of this operation is from c. 1910 when younger boys were placing on the factory.


Rochester Glass Wks………………………Rochester Glass Works, Rochester, New York (1862-1908). Alice Creswick in The Fruit Jar Works (1995:273) presentations this chronology for the Rochester Glass Works and succeeding firms, it appears that evidently from town directory listings researched via either herself or Dick Roller: Rochester Glass Works (1862-1881); Kelley & Co. (1882-1885); Kelley, Reed & Co. (1886-1887); Eugene Reed & Co. (1888-1889); E. P. Reed & Co. (1890-1894); Rochester Glass Works (1895-1898); F. E. Reed Glass Company/Works (1899-1900); Rochester Glass Works (1901-1908); F. E. Reed & Co. (or F.E.Reed Glass Co.) (1909-1927); Reed Glass Co. (1927-1946); and Reed Glass Co., Inc. (1947-1956). Several marks have been used at more than a few times by way of this manufacturing facility, and the exact time frame that every mark was used is not fully certain.  Known marks come with “Reed”,  “F.E.R.”,  “F.E.R.G.Co.”,  “R in a triangle”,  and “Rochester Glass Wks”. Some blob beer bottles are identified with the marking “Rochester NY Glass Works” embossed in a circle on the base. The complete manufacturing facility title may conceivably have been embossed on bottles relationship from anytime throughout the 1862-1908 period of time.    After a time of state of being inactive, the Reed Glass Company  plant at Rochester was once purchased by way of Castle-Hanson Corporation in 1959, and the “C-H” mark was used for some time frame thereafter. Later, Leone Industries, based in Bridgeton, New Jersey, purchased the plant and their “L in an unconnected sq.” mark was used on ware produced at Rochester as well as Bridgeton. Exact dates of later operations of this factory are unclear. (See “R in a triangle”, “C-H”, and “L in an unconnected sq.” marks). Rock hammer,  Scythe or Anchor-like image inside of rounded vertical triangle (triangle vaguely paying homage to teardrop shape),  as proven in photo……………….this glassmaker’s mark is noticed on base of dark woodland/emerald green Jägermeister liqueur bottle. Uncertain, possibly a tumbler producer in Germany (Deutschland).  If what corporate used this logo, please touch me, and I can give you credit score for the submission!

Who used this mark? Ron Ray 1991 (or other year, hand-etched on base of hand-crafted art glass hen paperweights) ……………… Phoenix Studios, Fayetteville, Arkansas. These birds, generally in blue glass, however from time to time in other colors, are very similar to the items made by Terra Studios, additionally of Fayetteville. (All birds marked “Leo Ward” at the base are merchandise of Terra Studios.) ROOT……………….see this web page: Root Glass Company, Terre Haute, Indiana (1901-1932). RP (frequently with 3-digit quantity) on the base…………………..Richards Packaging, Mississauga, Ontario, Canada.  This”RP” mark dates after 1982, and indicates manufacturing in Taiwan (via unidentified glass manufacturing facility(s)  for Richards. Richards instituted their later odd-looking “R” mark in 2005 (as shown, above in this page).  Also see “R”, “RIGO” and “R.G.CO.T.” marks.
