"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.
