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.

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.
