has anyone had problems with white 000013 not melting properly at 1450? Just recently started having problems. It stays pointy at the corners.
From Michelle l. Black
Michelle, 000013 is the stiffest standard glass we make, and even at full fuse 000013 keeps a bit of its square edge. Possible solutions: try a longer soak at 1450 or cap it with clear (if that would work with your design).
