Notes
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.

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. |
