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.
Typecodes	Leaded Frit Frits can contain 1% or 80% PbO so this category can be misleading, check the chemistry to find out.
