Is Clear or Starphire better for cast glass?
Most people would think that the colorless Starphire glass would yield the most beautiful cast glass. However, we’ve found that some of the dramatic effects of the thermal forming are diminished by the lack of any color. The Vitro clear glass that we use has a hint of green that is created by a higher percentage of iron oxide in the silica recipe for the plate glass. This hint of green yields a more dramatic piece of cast glass. In the image below, you can see how the ridges in the first panel of glass (Starphire) don’t show up as well as the second piece of glass (Clear).
