Antique Glass

Does anyone know the name brand of antique glass with a "diamond" embossed on the bottom?

This period is presented in glass different colors. Someone told me that he seemed "Heiz" (not sure of the spelling). Help!

Diamond logo (no letters or numbers inside )........ uncertain, may Diamond Glass Co, Montreal, Quebec (1891-1913) and Diamond Glass Company, Royersford, PA (1885-1990). (Diamond Glass Company of Royersford has been bought in 1985 for being part of Diamond-Bathurst, and in 1987 the plant was acquired by Anchor Glass Container Corporation, a plant that closed in 1990). Some bottles may also be products of the Illinois Glass Company, Alton, IL., That definitely used a diamond mark numbers and / or letters as in many types of bottles. Diamond with an inner ............ See "I under a" mark of Diamond. Diamond with the letter and the number or letter and number combination in it ......... Illinois Glass Company, Alton, IL, definitely produced at least some of them. Diamond with 2 -, 3 - or 4-digit number within ......... Illinois Glass Company, Alton, IL (1873-1929). (Figures within a diamond on various types of bottles produced some of the bottles are found at these basemarks Diamond / Dominion Glass Company, Montreal, Quebec, Canada and elsewhere, and Society diamond crystal, Royersford, PA (1885-1990) superimposed on a diamond oval [letter O] and ............. I. Owens-Illinois Glass Company, Toledo, OH (Headquarters) and location other plants (1929-present). Two examples of the brand presented here. This mark was used from 1929 (you can not actually recorded in the forms until the early 1930s) to c.1957. As there was a gradual transition to the brand new "(with diamonds removed) that took place during a period of four or five years (from 1954), some bottles of molds used were not re-registered as late as 1957 or 1958. (I have a soda bottle dated 1959 with the "old" brand "). However, after 1958, the vast Most bottles Oi lead to the "new" brand that was just an I in an oval. (See "I as a mark" O). In bottles very small, the mark may be permanent and T can be invisible, or only a small point. In the typical bottle, generally one on the left, right, and below the mark. (Note: This is the most common, but some bottles, such as bottles of liquor, marked by other means, and thus face a different configuration code.) number to the left of the diamond is the code number of the plant, the number the right is a date code and number below the logo of the mold cavity or serial number. Examples: # 2 install code representing the Huntington, WV plant "3" was the Fairmont, WV plant "7," said Alton, IL; "9", The Streator, IL facility "12" was Gas City, IN; "14" was the Bridgeton, NJ plants, etc. Some numbers have been reused for other plants open during recent years, however.
