Abstract
Coloured glasses absorb light, either broadly or sharply, in the ultraviolet, visible or in the near-infrared region of the spectrum so that the different colours are displayed. The colouring glasses should contain at least one of the colouring ions to perform their functions such as Fe, Ni, Co, V, Ce, etc. incorporated in the base glass. These types of coloured glass have been used in distinctive applications according to their transmission and absorption characteristics, for example, as optical filters such as neutral density filters, blue filters, and sunglasses (Weyl 1959).
