Notes
This is a USA pottery frit, Ferro now calls it Frit 5301-2.
Formerly Frit 4101. This was probably originally a porcelain enamel frit since it has a very high thermal expansion and a lot of fluorine (they need formulations that melt at very low temperatures).
The high expansion makes it useful in crackle glazes at 06 or to counter shivering in other glazes.

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. |
