Glass tesseras specially created for composing ornamental mosaics, characterised by the formal thickness of two flat elements made of industrial glass, which are superimposed and joined through thermic fusion and coloured during the process of fusion (or joining) of the same, with eliminating all risk of the two plates separating or coming unglued, something that could occur in a simple glued sandwich structure and with physical superficial effects of brilliance and/or refractivity, giving a visual effect of depth that cannot be found in products using the preceding technique.
