Notes

This is a USA pottery frit, Ferro now calls it Frit CC-274-2. This is very similar to Fusion frit 524 except that it does not have the 2% BaO.

As of 2008 Ferro only provides an approximate analysis, but the one here is historical (from previous sources).

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.
Materials	Fusion Frit F-524 A low fire base glaze, add 10% kaolin, adjust thermal expansion using other frits.
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.
Typecodes	Available from Laguna Clays
