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.

Materials	Frit Frits are made by melting mixes of raw materials, quenching the melt in water, grinding the pebbles into a powder. Frits have chemistries raw materials cannot.

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.
