The Annealer

The annealer is a kiln where the glass is put when it is finished.  The annealer is brought to heat and slowly cools down, generally overnight, so that the glass does not crack.  When hot glass is cooled at room temperature, it stresses and cracks from the shock.  Glass needs to "anneal" slowly.  An annealer can be programmed to run different cycles. (i.e. A very large or thick piece of glass will take longer to cool, and may need a longer annealing cycle.)
