"FSCGCL" Firing Schedule

Shimbo Crystal Celestite Schedule

No kiln will be able to achieve one or more of these rates of climb or drop. And, all but very small or thin-walled ware would crack. Fara’s intention is that the degree to which it is possible will determine how well crystals will grow.

Step °C °F Hold Time
1 100°C/hr to 250C  180°F/hr to 482F  0 2:32  
2 250°C/hr to 350C  450°F/hr to 662F  0 2:56  
3 500°C/hr to 1265C  900°F/hr to 2309F  0 4:46  
4 9999°C/hr to 1130C  17998°F/hr to 2066F  10min 4:56  
5 35°C/hr to 1050C  63°F/hr to 1922F  10min 7:24  
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.
