Goofus glass is an American term forpressed glass that was decorated with unfired enamel paint in the early 20th century by several prominent glass factories. It contrasts withenamelled glass, where the enamel is fired, making the paint far more durable. Because it was mass produced and relatively cheap, it was given as premiums with purchases and awarded as prizes at fairs. It was the firstcarnival glass, preceding the iridized product known today as carnival glass.
Articles produced included plates, bowls, vases, oil lamps, dresser sets, salt and pepper shakers and candle holders. Common colors were red, green and gold, the latter the most common.
Major producers includedIndiana Glass Company, Dugan Diamond Company and H. Northwood. These companies produced pieces that consisted of lines of pressed glass known asintaglio and paintedopalescent glass.
The term "goofus" now refers more to the technique of using unfired enamel paints on a piece of glass rather than to the glass itself. The term generally excludesmilk glass and painted jewelry, items produced after the 1930s, and items produced outside the US.
