| Body-tinted glass |
It is a normal float-clear glass into whose melt colorants are added for tinting and solar-radiation absorption properties. This reduces heat penetration in buildings. Coloured glass is an important architectural element for the exterior appearance of façades. It is also used in interior decoration (doors, partitions, staircase panels, mirrors,...).
Production is the same as in float glass production. The only variation is the colorants mixed at the beginning with the standard raw materials. Different additives may produce differently coloured glasses. Some of the most-used colorants and colours they produce are listed below:
