Carnival Glass

Classic Carnival Glass, defined as pressed glass with a pattern that has been iridized, was made in America from about 1907 to the early 1930s. Five major American glass companies produced Carnival Glass in this Classic Era: Fenton, Dugan-Diamond, Imperial, Millersburg and Northwood.

Glass companies in a variety of countries in Europe began producing Carnival Glass a few years later, in about 1914. Following are listed the major Non-American glass companies in Europe that produced Classic Carnival Glass. Please note, however, there are many that I have not listed including those in Australia, India and South America. The major producers of Carnival Glass in Europe in the Classic Era were in the following countries:

Czechoslovakia – Inwald
England – Sowerby
Finland – Riihimaki
Germany - Brockwitz
Poland – Hortensja
Sweden – Eda Glasbruk

Vaseline Glass

Vaseline Glass, defined as yellow-green glass that is made by adding Uranium Dioxide to the ingredients when the glass formula is made, can have a pressed pattern or be blown-moulded. Production began in the mid- to late-1800s and lasted until the mid-1940s. Vaseline Glass always turns a bright florescent green under a blacklight. The glass companies that produced antique Vaseline are too numerous to list, however a few are the same companies that produced Classic Carnival Glass and American Iridescent Stretch Glass.
