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.
