1700F Frit Melt-Off: Who is the winner? Not the lead bisilicate!

Melted balls of 15 frits on a ceramic tile

These were 10g balls melted using our GBMF test. We fired at a temperature far lower than typical bisque, notice how many of them are already melting well! Frit 3602 is lead bisilicate. But it got "smoked" by the Fusion FZ-16 high-zinc, high-boron zero-alumina! Maybe you always thought lead was the best melter. That it produced the most transparent, crystal-clear glass. But that is not what we see here. That being said, notice the lead is not crazing but the FZ-16 is crazing badly, that is a problem for many applications using this frit, it relies on a high percentage of KNaO. Notice something else: Each frit has a distinctive melt fingerprint that makes it recognizable in tests like this. Want to get some of this frit for pottery? You can't, Fusion Ceramics doesn't want to handle retail sales of smaller quantities.


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 Pemco Frit P-3E12
Materials Hommel Frit 432
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.
