Plate made with white reticello e with border in light blue paste. The reticello, already used in the 16th century, is made, like the filigree,   with round rods with white internal thread turned in the opposite direction to each other and, therefore, crossed during hot working to form a network. This plate also has a small air bubble in each rectangle which is created by pricking the still hot mesh. For the precision that must be had in crossing the threads it is a very difficult and daring technique. Certificate of guarantee of work performed entirely by hand and in Murano by Maestro Ravanello.
