All mosaics are produced following the original techniques dating back to the 16th century, which exalt the natural colour of every stone. As in the 16th century, every piece is cut with a simple saw made of a tree branch bent in the form of a bow with an iron wire stretched from end to end and covered with water and emery powder; the pieces are then glued together with a mixture of virgin wax and colophony. The artists personally follow the whole creative process and all mosaics are entirely produced in the laboratory of the Masters Iacopo and Bruno Lastrucci, situated in Via de’ Macci 9 and annexed to the Galleria Musiva, selling Florentine mosaics of own production.
