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.

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.
