Depression glass is glassware made in the period 1929–1939, often clear or colored translucent machine-made glassware that was distributed free, or at low cost, in the United States and Canada around the time of the Great Depression.
Common colors are clear (crystal), pink, pale blue, green, and amber.
Less common colors include yellow (canary), ultramarine, jadeite (opaque pale green), delphite (opaque pale blue), cobalt blue, red (ruby and royal ruby), black, amethyst, monax, and white (milk glass).
Popular and expensive patterns and pieces have been reproduced, and reproductions are still being made.
It was distributed through jewelry and department stores from the 1920s and continuing after the Great Depression through the 1950s, and was an alternative to fine china.
