Alternate Names: 2PbO.3SiO2
This term refers to frits having 1 molar part of lead and 1.5 of silica.
Melts at a slightly lower temperature than lead bisilicate frits which are 1 part lead to 2 of silica.
|Materials||Lead Bisilicate Frit|
Materials that source Na2O, K2O, Li2O, CaO, MgO and other fluxes but are not feldspars or frits. Remember that materials can be flux sources but also perform many other roles. For example, talc is a flux in high temperature glazes, but a matting agent in low temperatures ones. It can also be a flux, a filler and an expansion increaser in bodies.
|Frit Softening Point||860-1040C M|
