Ceradel Frit C 1251

Alternate Names: C1251 Fritte, C 1251 Fritte, Ceradel Frit 1251

Description: Lead monosilicate frit, Monosilicate de plomb

Oxide	Analysis	Formula
SiO2	21.21%	1.00
PbO	78.79%	1.00
Oxide Weight		283.28
Formula Weight		283.28

Notes

This analysis is guessed, the manufacturer calls it a lead monosilicate and provides the approximate chemistry of (SiO₂ - 15-40%, PbO 60-100%). However, since the lead monosilicate analysis is theoretically 1:1 lead:silica that is what we have assigned here.

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.
Materials	Ceradel Frit C 1249
Materials	Lead Bisilicate Frit A standard frit of 1 molar part of PbO and 2 of SiO2. It is considered stable and non-leachable.
Materials	Lead Monosilicate Frit A standard frit of 1 molar part of PbO and 1 of SiO2. It melts lower than a lead bisilicate.
Typecodes	Leaded Frit Frits can contain 1% or 80% PbO so this category can be misleading, check the chemistry to find out.
