It is common belief that Steuben’s Black glass is opaque. Most certainly it is for all intents and purposes; however, light will appear pinpointed as a potassium permanganate,i.e., violet-red. The common pressed glass known as black amethyst has the same characteristic.

It will be found in various decorative items and in limited luncheon set pieces such as sherbets, plates and goblets. It is, as is all Steuben, light in weight and very skillfully blown.
