Glass that is curved or bent into a convex or concave shape is known as Bent Glass. The shape is achieved by gradually heating the glass till it is softened and then it is converted to the desirable shape. The curved glass can be toughened before it is cooled. The characteristics of Bent glass are –

  • Bent shape can be achieved in glass ranging in between 3mm to 19mm thickness.
  • They have to be handled very carefully as they are prone to breakage because of the curved shape.
  • Each piece of glass has to be tailor made.

The three commonly used bent glass are

Curved annealed glass – This glass is used for showcasing purpose in store fronts where safety glass is not a very major requirement or issue.

Curved laminated glass -In this bent glass an extra PVB layer is attached between two layers of glass. This makes the glass very strong. In case it cracks the glass pieces do not fall but are held together in place because of the PVB layer.

Curved tempered glass -The curved glass is tempered before being cooled. The tensile and compressive stresses  make the glass very strong. Once broken it shatters into extremely small pieces which have chances of falling and injurying people.
