This was used to teach the employees glass making techniques.
In the collection of Glenn Drummond.

These were made by the workers at the factory "for fun' not a production item.

Hemingray frogs were made in the 1930's by workers during down time at the factory. The original ones come in ice blue and 7 Up-green. When Hemingray/Owens-Illinois closed its doors an employee of the plant got to take the mold. The mold has been used to reproduce these frogs. Thanks to Jim and Earl for sharing these pieces with me.

The ice blue one pictured on this page is a original. The other are later productions.

This is a Hemingray "glass head". These are very rare (This is the only one I know of). Thanks to Dean for the photo of this! This lamp shade was patented on May 14, 1878. (Patent No. 10,678)

Hemingray made Jelly jar with HGCO monogram on the lid. Example in photo is original jar with original lid.

This jar is from the time period of 1857-1860. It is the only known example of a Hemingray glass item with the Gray & Hemingray bros embossing on it. Most likely this jar was used for photographic development, as Peter Smith (P Smith is embossed on the jar) has patents for Photographic related process
