Mastering Glazes Cone 6

From page 144 in Mastering Glazes.
Step 1 provides time for all remaining or residual water in glaze and clay to evaporate.
Step 3 approaches the final temperature more slowly and gives the glaze and body time to finalize their interaction with each other.
Step 5: Cooling more slow through the 1025 down to 800 range is important if you want multiple phases or crystal (and associated matte) effects to develop.

Step °C °F Hold Time
1 55°C/hr to 105C  99°F/hr to 221F  60min 2:58  
2 200°C/hr to 1080C  360°F/hr to 1976F  0 7:51  
3 85°C/hr to 1200C  153°F/hr to 2192F  15min 9:30  
4 275°C/hr to 1000C  495°F/hr to 1832F  0 10:14  
5 70°C/hr to 760C  126°F/hr to 1400F  0 13:40  
6 0°C/hr to 30C  0°F/hr to 86F    13:40  
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.
