By the term "glass fusion" means the construction of a new glass plate that will serve to produce the objects and jewelry. This is done in an assembling process, with which they are put together pieces of glass and other materials (gold leaf, silver leaf, murrine cane zanfirico): the various elements, if processed at very high temperatures, blend in irreversible. The product, after being assembled, is baked in ovens at high temperature (from 700 to 850 degrees), and thereafter, at the end of the cooking cycle, is cooled very slowly in order to obtain a product qualitatively optimal : the latter passage allows, in physical terms, to reach again the molecular stability that the product possessed before cooking.
