Description: Low expansion high CaO balanced boron source
This is a USA pottery frit, Ferro now calls it Frit CC263-2. It is available in small quantities at lagunaclay.com. They call it an "alkaline, alkaline earth alumina borosilicate" and say it is "a well-balanced composition without barium. Typically used as an all-fritted glossy glaze in the general range Orton cone 04-4." This is likely a major constituent in their low fire glazes.
Was formerly #CC268.
Ferro only publishes an approximate analysis as of 2008, however this one was historical (from previous sources).
It is balanced cone 02-1 clear glaze.
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.
