Depression glass is clear or colored translucent glassware that was distributed free, or at low cost, in the United States and Canada around the time of the Great Depression. 

Most of this glassware was made in the central and mid-west United States, where access to raw materials and power made manufacturing inexpensive in the first half of the twentieth century. More than twenty manufacturers made more than 100 patterns, and entire dinner sets were made in some patterns. Common colors are clear (crystal), pink, pale blue, green, and amber. Less common colors include yellow (canary), ultra marine, jadeite (opaque pale green), delphite (opaque pale blue), cobalt blue, red (ruby & royal ruby), black, amethyst, monax, and white (milk glass).

Depression glass has been very collectible since the 1960s. Rare pieces may sell for several hundred dollars.
