Description
A milky white, translucent Glass. Opal, or opalescent, glass was first made in the mid-1800s but not patented until 1880 by Louis Tiffany. Tiffany and J. La Farge prepared large sheets of opal glass for use in windows. Opal glass is made white by the addition of Calcium phosphate (bone ash) and opalescent by the addition of fluorides (Fluorspar, Cryolite, or Lepidolite) and/or Arsenic. Opal glass was used for light shades, table tops, and cosmetic jars.
