ANNEALED GLASS

Is glass without internal stresses caused by heat treatment (i.e. by 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 being quenched. Annealed glass breaks into large, jagged shards that can cause serious injury, and thus annealed glass is considered a hazard in architectural applications. Building codes in many parts of the world restrict the use of annealed glass in areas where there is a high risk of breakage and injury, for example in bathrooms, in door panels, fire exits and at low heights in schools or domestic houses.
