Free Former Mold Set #10
Free Former Mold Set #10 Makes the bottom piece of a double glass lamp. There are 2 different sizes of the center hub and they can be used with any combination of the spokes. Use the shorter wider hub with all 4 spokes, with a 9"x 9" piece of 2 layer glass, and you'll get the a similar base to the blue and white one shown here. This format gives a more uniform shape and allows a space for the cord to pass through.
These are used with the following schedule in my skutt kiln. 250/hr to 1230 and hold 20 minutes, You would need to adjust time and schedules based on thickness of glass, size of glass, and your kiln.
