"FSHP3" Firing Schedule

Shimbo Crystal Holding Pattern 3

From page 139 in Crystal Glazes book 2.

Step °C °F Hold Time
1 100°C/hr to 250C  180°F/hr to 482F    2:32  
2 250°C/hr to 500C  450°F/hr to 932F    3:32  
3 500°C/hr to 1221C  900°F/hr to 2229F    4:58  
4 999°C/hr to 1075C  1798°F/hr to 1967F  15min 5:22  
5 100°C/hr to 1100C  180°F/hr to 2012F  15min 5:52  
6 100°C/hr to 1075C  180°F/hr to 1967F  15min 6:22  
7 100°C/hr to 1050C  180°F/hr to 1922F  15min 6:52  
10 100°C/hr to 1075C  180°F/hr to 1967F  15min 7:22  
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.

Bory 1

These Bory 1 crystals (colored with nickel, iron and cobalt) fired using the FSHP3 schedule. Rather than going to a temperature as fast as possible, the kiln climbs (whether going up or down) at a rate of 100° per hour.
