Dugan Carnival Glass 'Big Basketweave' Marigold Swung Vase

Carnival glass, also known as iridescent glass, was produced from the early 1900s to the 1930s, with Dugan Glass Company being one of its most prolific manufacturers. This type of glass was made by applying a metallic salt solution to the surface of molten glass, which then created a shimmering, iridescent effect when fired. It was often given away as prizes at carnivals and fairs, hence its name, and was popular for its affordability and decorative appeal.
