Annealed Glass

Annealed Glass


Annealed glass is glass produced without internal stresses imparted by heat treatment, i.e., rapid cooling, or by toughening or heat strengthening. Glass becomes annealed if it is heated above a transition point then allowed to cool slowly, without the application of a carefully controlled airflow (quenching.) Glass is treated with heat in order to change its properties by the annealing process. Annealed glass is the most common glass used in windows. It is also known as a standard sheet of float glass. Annealing is actually a process of slowly cooling glass to relieve internal stresses after it is formed. The shaped glass is annealed to relieve the stresses caused by bending. Glass, which has not been annealed, is liable to crack or shatter when subjected to a relatively small temperature change or mechanical shock. Annealing glass is critical to its longevity. If glass is not annealed, it will retain many of the thermal stresses caused by quenching and significantly decrease in strength.

Annealed Glass can be used anywhere that safety codes are not an issue, like is the case in showcases, display cases, china cabinets, windows and wall units. We can bend any thickness from 1/16 of an inch to one inch. Any of the glass listed under Glass Types for Fabrication can be used. Also, we can bend annealed glass to any radius or custom shaped imaginable.
