Definitions

  • Various fluxes such as B 0 and P 0 may be present but, preferably, in amounts less than about 5% by weight each.
  • PbO while desirably absent, may be included in amounts up to about 3% by weight.
  • various coloring agents e.g., C0 0 Cr O V 0 CuO, and NiO, may be present in very small amounts to impart a neutral shade to the glass.
  • conventional fining agents such as AS203 and Sb O may be added, where desired.
