Opaline glass

The term "opaline" in current times refers to many forms of opaque and colored glass. In France the term opaline is used to refer to multiple types of glass and not specifically antique colored crystal or semi-crystal. The idea that the term opaline is strictly antique French crystal is incorrect. For instance when shopping in France you may see a piece of American slag glass for sale labeled opaline in reference to the color of glass and not the age, origin or content of the glass. Most all opaline glass is not branded or signed.
