Shimbo Crystal Holding Pattern 3

These Bory 1 crystals (colored with nickel, iron and cobalt) were grown with the same target temperatures as those in the holding pattern 2, but rather than going to a temperature as fast as possible, the kiln was instructed to get to each temperature (whether going up or down) at a rate of 100° per hour.

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 1260C  900°F/hr to 2300F    5:03  
4 999°C/hr to 1075C  1798°F/hr to 1967F  15min 5:29  
5 100°C/hr to 1100C  180°F/hr to 2012F  15min 5:59  
6 100°C/hr to 1075C  180°F/hr to 1967F  15min 6:29  
7 100°C/hr to 1050C  180°F/hr to 1922F  15min 6:59  
10 100°C/hr to 1075C  180°F/hr to 1967F  15min 7:29  
Start temperature assumed: 25°C or 75°F
100°F is 37°C, but 100 fahrenheit degrees is 55 celsius degrees, that is an important distinction to understand the above temperature conversions.
