"FSCGB1" Firing Schedule

Shimbo Crystal Holding Pattern 2

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 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 1260C  900°F/hr to 2300F  0 4:45  
4 999°C/hr to 1075C  1798°F/hr to 1967F  90min 6:26  
5 999°C/hr to 1100C  1798°F/hr to 2012F  15min 6:43  
6 999°C/hr to 1075C  1798°F/hr to 1967F  60min 7:44  
7 999°C/hr to 1050C  1798°F/hr to 1922F  15min 8:01  
8 999°C/hr to 1075C  1798°F/hr to 1967F  60min 9:02  
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.
