The technique of the mosaic in glass cut enamel derives directly from the mosaics of Byzantine era, more precisely from the Byzantine era in mosaic.
Pieces of Murano glass enamel “tessere” are of quadrangular form, between 3 and 10 mm. and thick about 5 mm.
The tools used for cutting and shaping the pieces are “martellina” and “tagliolo” fixed to a wood log. The “tessere” are applied with tweezers.
The techniques we use to realize this type of mosaic are two: the indirect technique and the direct one.
In the first technique glass pieces, previously cut in various sizes, are glued to on a papery support represented by the photocopy in negative of the select subject for the execution of the mosaic.
Only in a second moment the mosaic is upset and applied, with a mixture of glue and cement, in a wood container.
To this point the mosaic is put in equal and then plastered among piece and piece. In the direct technique, instead, glass pieces, cut to measure with the martellina, are directly inserted in a wood cassina on a base of plaster.
