Mercury Glass or Silvered Glass
This web page describes “mercury glass,” or “silvered glass,” as it was sometimes called—a double-walled glass with a coating of silver coloring on the inside. In the 19th century, this product was a cheaper substitute for real silver. In the early days of its production, mercury or mercury products were used to create the silver colored inner coating. However, mercury proved unsuitable for this purpose, and very little silvered glass actually contains mercury; in most pieces silver nitrate was used for the coloring. This web page provides a picture of an example of mercury or silvered glass and indicates the manufacturer markings that can be found upon English and U.S. specimens.
