	Dominican Glass Co. Ltd.	Upper case D - from Dominican Glass Co. in Canada. Dominion Glass Company Ltd. Dominion Glass was a major Canadian glassmaker with product lines ranging from bottles & jars to pressed tableware and art glass. In its early years, it was a corporation that grew through multiple takeovers of smaller firms, and the original company was the Foster Brothers Glass Works in Quebec established in 1855. Renamed in 1890 to the Diamond Glass Company Ltd., more acquisitions meant that the company operated plants in Nova Scotia, Quebec and Ontario. New ownership was the reason for a name change to the Diamond Flint Glass Company Ltd. in 1903. Previously in 1897, Diamond Glass had acquired a small Montreal company called Dominion Glass, which had been in operation since about 1885. This name was adopted eventually by Diamond, and 1913 finally saw the incorporation of the new Dominion Glass Company Ltd.
