Annealing is the gradual cooling of the glass down to room temperature. Especially for smaller, simpler objects, annealing may be incidental to the process of manufacture, but in larger or more complex products it commonly demands a special process of annealing in a temperature-controlled kiln known as a lehr. The annealing of glass is a very important process.

Each piece will be placed in the annealing oven for a slow cooling process. Our annealing furnaces run on a computer program and the length of time for pieces the size we tend to make is about 16 hours. Annealing a basic piece requires from five to eight hours, while larger more complicated works often remain in the oven for several days; glass too quickly cooled breaks or has weaknesses.
