This is a USA pottery frit. Ferro now calls it Frit 3269-2.

Useful for partially fritted gloss tile glazes for cone 06-01. Balanced enough for use alone (if the application can tolerate its high thermal expansion). Like Frit 3110, the high expansion makes it suitable as a crackle glaze (with an addition of 10% kaolin).

Unlike Frit 3110, this has significant B2O3 and Al2O3 and almost no CaO.
