Typecodes	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.

Lead bisilicate is extremely resistant to leaching by dilute acids, including gastric juices, which reduces its toxicity and offers the maximum safety of any of the lead products. Available in either granulated or ground form.
