The year of Fenton
It's hard to believe, but Carnival Glass is one hundred years old this year. Fenton introduced Carnival in 1907 and Northwood, Imperial, Dugan/Diamond, and Millersburg soon followed. Fenton is the only one of these companies to have survived.
What is Carnival Glass?
This is a question that confuses many people new to collecting Carnival. Primarily, Carnival Glass is pressed glass that has had an iridescent coating applied. Remember, if it isn't iridized, it isn't Carnival.
Pressed glass? This is glass that has been formed by being pressed into a mold while in a hot molten form. As it cools, it takes on the shape and detail of the mold. Once removed from the mold, and while still relatively hot, it is sprayed with metallic salts in liquid form which gives it the "oil-on-water" multicolor appearance.
Carnival Glass was first produced by Fenton in 1907 and continues to be made today. There were 5 or 6 major makers of it originally, but Fenton is the only one of the original group still in business.
