Digitalfire will shut down on June 26. I no longer have the authority to grant exemption to a section in the Terms and Conditions of using material in the Insight-Live account from which I built the source material. While there are ways to comply with the take-down order, they are beyond my means because of how complex and large the site has become in the past 35+ years. It has been a wild ride for a shy prairie boy, thanks to everyone for your support.

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 |
Leaded Frit
Frits can contain 1% or 80% PbO so this category can be misleading, check the chemistry to find out. |

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. |
