The Hemingray Glass Company

This site was created to show examples of the products of the Hemingray Glass Company. Hemingray is known for their insulators, but they also made many other items. Bottles, fruit jars, kerosene lamps, tableware, and other misc. items are but a few of the items they produced.

Here is a grouping of glassware made by the Hemingray Glass Co. during the 1880's. The bird dish in back was patented in 1876 and the anvil toothpick holder was patented in 1887.

These glass syrup pitchers, called molasses cans in the 1880's, were produced by Hemingray in several colors and paint patterns.

This lamp was advertised in 1888 in four sizes. As you can see, this actually. comes in five sizes.
