Summarize the following:
When the kiln is firing, it will be extremely hot, so avoid touching it directly. Use the following casting schedule on your kiln to fuse the glass:  Turn the temperature to 250 °F (121 °C) for 10 minutes. Raise the temperature to around 1,465 °F (796 °C) and leave it on that temperature for 10 minutes. Turn the heat down to 950 °F (510 °C) and leave the kiln at that temperature for 1 hour. Decrease the temperature to 850 °F (454 °C) and wait for 15 minutes. Turn the heat to 100 °F (38 °C). Leave the kiln closed and wait a day before you open it. Don't touch the mold or reach into the kiln until the outside is cool to the touch. The time it takes the kiln to cool will vary. Measure the temperature of the kiln an hour after it fired. This difference between the temperature it fired at and the temperature an hour later is the cooling rate per hour for the kiln. For example, if your kiln fired at 1,500 °F (820 °C) and an hour later the temperature is 1,250 °F (677 °C), the cooling rate is 250 °F (121 °C) per hour. Put gloves on when removing the glass from the kiln as it still might be quite warm. Place the glass on a steady work surface. Use a diamond pad or a grinding stone to make it smooth and get rid of any blemishes. Rub uneven or imperfect areas of the glass with the diamond pad or grinding stone to smooth out the imperfections. Hold the mold gently as you rub it with the diamond pad or grinding stone. Kilns are programmed to turn off after they're finished firing. If you want to, you can force the kiln to turn off by using the on/off switch on the kiln. When you're finished with the kiln, plug it out to cut off the electrical supply reaching it.

Summary:
Fire your kiln to fuse the glass. Let the kiln fully cool down. Take your mold out of the kiln and refine it. Unplug the kiln when you're finished using it.
