Cased glass has been around for awhile. The term "case", when it comes to glass, means two layers of glass. Typically the inside layer is white glass while the out side color can be almost anything from green to red to amber. Within this category, you will find more styles like melon, Tam-O-Shanter, embossed. Those terms describe the shapes more than than the color or type of glass. Need help?
