Be careful, the glass is very hot in the microwave kiln reaching temperature like 1000 celsius degrees and over, so be careful. The difference in temperature, or variance, must fall with what we call the 10-10-5 rule. The first 10 applies to the 10 locations on the sheet where temperature must be known: the four corners and center of both sides. The next 10 refers to the fact that the temperature must not vary more than 10°F on any of the 10 sheet locations.Sand casting is suitable for both steel and iron valve castings.
