Kopp Glass Company

Kopp Glass Company is located in Swissvale, Pennsylvania ()is is still in business today producing industrial lighting glassware). In 1928 they introduced a line of glassware called "Modernistic" inspired by the Ruba Rombic line from Consolidated Glass Company . Although their Modernistic line of glassware is collectible it will not command the same prices as the Ruba Rombic produced by Consolidated Glass Company.

Kopp produced vases (in 2 sizes) and a powder jar in their Modernistic line. You will sometimes find the raised KGI logo on the bottom of the Kopp vases.

The Kopp powder jar is often confused with the Ruba Rombic powder jar. The Kopp powder jar is normally found in light green frosted or white frosted glass. The powder jar lid is round and the powder jar top where the lid goes on has a couple of grooves in the glass. The Ruba Rombic powder jar lid is very angular as opposed to round. Some unscrupulous dealers try to pass off the Kopp Modernistic powder jar as a Consolidated Ruba Rombic powder jar. The Kopp Modernistic powder jar is a $150 or so item while the Consolidated Ruba Rombic powder jar is a $800 to $1,200 item. Make sure you know what you are buying!!

The most desirable items in the Modernistic line are small or large vases in red glass (also made as small table lamps). Kopp also made their vases in black glass which is extremely rare (only one example of the large size vase has turned up). A powder jar in red would be a real find.
