Description: Lead bisilicate frit
Oxide | Analysis | Formula | |
---|---|---|---|
PbO | 65.00% | 1.00 | |
SiO2 | 35.00% | 2.00 | |
Oxide Weight | 343.38 | ||
Formula Weight | 343.38 |
Their web page does not give the chemistry, but does indicate the presence of Al2O3 and KNaO. We assume these are in small amounts since they call this a lead bisilicate.
Materials |
Frit
Frits are made by melting mixes of raw materials, quenching the melt in water, grinding the pebbles into a powder. Frits have chemistries raw materials cannot. |

Leaded Frit
Frits can contain 1% or 80% PbO so this category can be misleading, check the chemistry to find out. |
Typecodes |
Frit
A frit is the powdered form a man-made glass. Frits are premelted, then ground to a glass. They have tightly controlled chemistries, they are available for glazes of all types. |
Frit Melting Range (C) | 980-1020C |
