Description: Low lead calcium silicate 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.
Hommel Frit 344
Pemco Frit Pb-349
General Frit GF-18
Frits can contain 1% or 80% PbO so this category can be misleading, check the chemistry to find out.
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.
