The Fluxing Agents Of Muranese Glassmakers. Part 3. Saltpetre (In Italian)

Saltpetre entered the scenery of the Muranese glassmakers in the last decade of the Seicento and soon became an indispensable element for the production of Bohemian style crystal glass and most enamels and rods for bead making. In order to enable the Muranese glassmakers to face foreign competition, since 1739 the Venetian Republic allowed many glassmakers to obtain saltpetre at cost price.
