Do glass beads need annealing? Whilst a round or stubby cylinder bead is less likely to crack than any other shape and you can wear these beads without much fear of them cracking, other bead shapes require annealing. Glass is a fragile product and annealing takes away some of the fragility.
Why must glass be annealed? The process of annealing glass relieves internal stresses, which could otherwise leave it susceptible to cracking or shattering in response to minor mechanical or thermal shock. This makes annealing a vital step in the production of strong, stable, and heat-resistant glass.
How do you anneal glass beads in a kiln? Beads are annealed by placing them in a kiln (or annealing oven) usually heated to between 900-1100°F and slowly running them through a controlled cooling cycle.
How do you cool glass beads? Glass is sensitive to breakage as it cools through the annealing range. This is approximately 950°F/510°C through 700°F/371°C. The larger the piece, the slower it must cool. To safely cool flame-worked glass beads, anneal them in your kiln using the bead door.
