Hazel Atlas produced glass tableware in the 1920s, 1930s and 40s, most commonly in the typical Depression era transparent glass colors of light green,  clear (crystal), pink  and yellow (actually a light yellow leaning toward yellow-amber or topaz).  Their green Depression era glass contains uranium, so pieces will glow under a black light.  Some patterns were also made in cobalt blue and, in a few cases, amethyst.  Most of the items in these pattern glass sets were not marked,  but are fairly well known and recognized by collectors who specialize in studying tableware patterns of that era.
