<p>The component consists of a transparent substrate (10) with at least one surface (11, 12) partly or wholly coated with opaque, translucent or transparent coloured or clear deposits (25, 26, 29, 30), and differs in that the substrate is made from a material resistant to a temperature of over 500 degrees C, such as quartz, spinel, corundum, sapphire or mineral glass, and the deposits are of enamel. The deposits are located in recesses in one or both of the substrate's main surfaces which allow their thickness to be varied to produce different tints or a hologram.</p> |
