This is a fully aspirated, resistively heated commercially available, Glass Tempering Furnace used to evaluate typical “window” sized coated glass in a production environment. It is used to assure our coated glass products can be Tempered strengthened accordance with international standards requirements such as ASTM and EN. The process of tempering glass is simple in principle. The coated glass is heated uniformly to
a temperature above its softening point. The surfaces are then rapidly cooled causing them to form compressive stresses up to 25% of the thickness of the glass and then cooled to a temperature suitable for manual handling.
This procedure improves the lateral impact strength of glass and ensures that if it is broken, it minimizes the risk of personal injury by breaking into small Dice-Size pieces. The tempered glass is then visually inspected for defects, and then spectrophotometric properties are evaluated Quality
