Description: Leaded boron low alumina frit
We have another analysis that does not include the ZrO2 (other item percentages adjusted accordingly).
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.
Ferro Frit 3417
Pemco Frit Pb-63
Fusion Frit FL-51
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.
