The Archive preserves and exposes materials and instruments for making mosaics. There are some samples of modern mosaic tiles, made in glass paste or natural stone, like marble.

The Archive exhibits also ancient tiles from paleochristian and byzantine mosaics, that have been used by conservators since the second post-war period for chromatic comparisons. At the end, are exposed traditional cutting tools, donated by Orsoni Smalti Veneziani.

The contemporary mosaic can be composed of multiform materials, enamels, marbles, pebbles and then wood, iron, ceramic, and also extravagant materials, like sugar cubes. The traditional one, instead, is made with natural cutting materials, like stones, or artificial materials like glass and cotto.
