I use a fairly old ceramic kiln with high, medium and low controls and a digital programmer that allows me to only set the final required temperature and whether to soak or not. I keep meticulous records of how long it takes to reach certain temperatures, 930 deg centigrade for a melt. Number each firing and use a new page for each firing, recording what happens whether the result is OK or excellent or total disaster.
I take it you are using glass with the same COE, all Bullseye Fusible or Spectrum Fusible for example.Sometimes you can use Spectrum Waterglass if you do the compatibility testing first.
I like to keep things simple so I know it takes about 4 hours for my kiln to heat up to 930deg cent. I soak for 2 hours at that temperature to give enough time for the glass to completely melt and run out of the pot. Then if i can't be bothered to flash vent, I just turn off the kiln and allow it to cool naturally. I try not to open the kiln door till the temperature is about 45 deg cent.
