lampwork beads Kiln Annealed
By annealing the glass beads, they are guaranteed hard as rocks, durable enough for everyday wear with long lasting heirloom quality. When a glass bead is finished, the hot bead (while still on the mandrel), is placed in a kiln heated at 960°F. The annealing process releases the stress from the glass and slowly cools the beads down to room temperature. Cooling the glass beads too quickly will cause them to crack.
