What Is Carnival Glass?
Carnival glass is molded or pressed glass that features a distinctive iridescent surface treatment. Manufacturers created the colorful finish by applying metallic salts to hot glass before firing it.
The result was a dazzling rainbow sheen that reflected light in various colors, including purple, blue, gold, green, and red.
Originally produced as an affordable alternative to expensive art glass, carnival glass became popular during the early twentieth century. It was often given away as prizes at fairs, carnivals, and promotional events, which led to its modern name.

The History of Carnival Glass
Carnival glass first appeared in the United States around 1907. Glass manufacturers sought to create attractive decorative items that resembled luxury art glass but could be produced at lower costs.
Several companies quickly entered the market, producing hundreds of patterns and shapes.
As tastes changed during the 1920s, demand declined significantly. Production slowed, and many patterns disappeared entirely. Today, those discontinued patterns are among the most sought-after collectibles.
The revival of interest in carnival glass began in the 1950s and continues today among collectors worldwide.
