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. Insight-live.com is not affected by this.
Fired at 350F/hr to 1750F and held for 15 minutes. Frit 3110 has taken off. And F75, 3195 and 3134 (the latter two having big differences in surface tension).
| Materials |
Ferro Frit 3110
High sodium, high thermal expansion low boron frit. A super-feldspar in clay bodies. Melts a very low temperatures. |
| Materials |
Ferro Frit 3124
A commonly available calcium borosilicate frit. |
| Materials |
Ferro Frit 3249
A magnesia borosilicate frit. Very low thermal expansion and melting point. Invaluable in pottery to increase the MgO in glazes and thereby prevent crazing. |

| Materials |
Fusion Frit F-75
High sodium, high thermal expansion low boron frit. An equivalent of Ferro Frit 3110. |
| Materials |
Fusion Frit FZ-16
The champion in our frit melt-off competitition. This frit showcases the amazing fluxing power of boron and zinc working together. It is 15.5% ZnO. |
| Materials |
Fusion Frit F-38
High strontium low alumina borosilicate flux. |
| Materials |
Fusion Frit F-69
A magnesia borosilicate frit having very low thermal expansion and melting point. Commonly used as a substitute for Ferro frit 3249. |
| Materials |
Ferro Frit 3602
A lead bisilicate frit with 2.5% alumina oxide. |
| Materials |
Fusion Frit F-524
A low fire base glaze, add 10% kaolin, adjust thermal expansion using other frits. |
