Set the kiln base on a flat surface and set a piece of kiln paper on the base.
Place a piece of Fuseworks microwave glass on the kiln paper.
Decorate the glass in a design you like. Arrange pieces of confetti or other bits of Fuseworks microwave glass onto the first piece of glass. Set them in a pile or arrange them in a design on the first piece of glass until you are pleased with the results.
Insert the kiln base in the microwave. Place the lid on the kiln base.
Set your microwave to three to four minutes for an 800-watt machine and two to three-and-a-half minutes for an 1100-watt to 1200-watt machine.
Remove the kiln from the microwave using heat-resistant gloves, and allow the glass to cool for 30 minutes. Remove the glass from the kiln.
