The Hemingray Glass Company had factories in Cincinnati and Covington, Kentucky with main production in Muncie, Indiana.

Although Hemingray was best known for its telegraph insulators, the company produced many other glass items including bottles, fruit jars, pressed glass dishes, tumblers, battery jars, fishbowls, lantern globes, and oil lamps.

To give an overview of the large variety of styles produced, the following table contains the twenty most common.

The CD number is from a classification system developed by collectors that refers to the shape of the insulator, and is independent of the Hemingray Glass Company.

Due to slight modifications in design over years of production, single styles can span multiple CD numbers.
