DIY Microwave Kiln | Fuse Glass in Your Microwave : 32
If the silicon carbide ring has cracked, most likely the plaster was too strong or you did not press the grit tightly together. You want the plaster to crule around the silicon carbide ring. If it''s too strong, the silicon carbide will stick to it too good and when the plaster cracks the carbide will also crack.
