GC106 Base for Crystalline Glazes

This base can give extremely brilliant colors; I’ve had particular success with red copper oxide. I’ve also noticed that cobalt is far less likely to felt up when used with this glaze, even when a large amount of colorant is used. Mixtures incorporating ilmenite and/or rutile work very well with this recipe, giving very large, quickly growing crystals. The crystals do not show the variation in shape one sees with the Ferro 3110 based glazes.

Step °C °F Hold Time
1 100°C/hr to 200C  180°F/hr to 392F  0 2:02  
2 250°C/hr to 500C  450°F/hr to 932F  0 3:14  
3 500°C/hr to 1275C  900°F/hr to 2327F  0 4:47  
4 9999°C/hr to 1130C  17998°F/hr to 2066F  15min 5:03  
5 30°C/hr to 1075C  54°F/hr to 1967F  0 6:53  
Start temperature assumed: 25°C or 75°F
"Fahrenheit degrees" is not the same as "degrees Fahrenheit". A 100° reading on a Fahrenheit thermometer is equal to a 37° reading on a Celcius thermometer. But "100 Fahrenheit degrees of temperature change" is equivalent "55 Celsius degrees of change". That is an important distinction to understand the above temperature conversions.

With a little iridescence from post-fire raku. The green is a true emerald green and very brilliant. Crystals do form very fast, however, and I have seen them attain an entire centimeter in diameter in as little as fifteen minutes
