Fired at 350F/hr to 1650F and held for 15 minutes. FZ16 has turned crystal clear and spread out across the runway (has low surface tension). Frit 3110 has so much surface tension that the flow can be lifted off the tester. Since 1600F Gerstley Borate has gone from unmelted to passing all the rest!
Fired at 350F/hr to 1600F and held for 15 minutes. Frit 3134 is still expanding. 3602 and FZ16 are off-ramp. F-75 is starting to flow. Gerstley Borate has suddenly shrunk. Frit 3110 is demonstrating its wide range, slowly softening more at each temperature.

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 |
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-524
A low fire base glaze, add 10% kaolin, adjust thermal expansion using other frits. |
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 3134
A frit with 23% B2O3. The most common of frits used in pottery in North America. Around the world, other companies make frits of equivalent chemistry. |
Materials |
Ferro Frit 3195
A commonly used boron frit, it is a balanced glaze all along at cone 06-02 (with the addition of 10-15% kaolin). Not fully glossy. |
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. |
