The Capitolare degli Specchieri of 1764
In 1762 the Senate of the Serenissima Republic decided to re-order the laws regulating glass-making corporations, namely the one from Murano and the three others that had spramg from it:
Specchieri, Margariteri, Perleri. The Art Inquisitor's duty was to define the principles by which materials were to be categorized and draw up regolations, after holding in-depth consultations with the heads of each corporation.
The Capitolare degli Specchieri, a capitulary text for mirror makers, was presented on January 3, 1764. It particularly discussedv the tests one had to overcome to become a Master, as said trails had become too flexible and permissive over time. Mirrors were obtained by smoothing down the thickest, most regular and homogeneous sheets available and Muranese glassmakers could only sell to the Mirror makers of Venice.
Yet, it was necessary to establish clear laws regarding less perfect sheets that could be used to make less refined mirrors for foreign nations.
It also became essential to regulate the activities of workers from Friuli who started making mirrors illegally. Finally, it also proved necessary to draw up laws regulating the sector dedicated to providing assistance for sick or indigent corporation partners.
