In this video, a crimp-edge molding tool sandwiches the glass between a solid form on the inside and metal jaws on the outside to create a quatrefoil shape. This technique would be the last step in the making of a quatrefoil goblet.

The Venetian glass industry enjoyed a golden age during the Renaissance. By the early 1500s, the wonders of Venetian glass were well known throughout western Europe. Not well known, however, was how these objects were made. Until now. The result of 30+ years of research by William Gudenrath, The Techniques of Renaissance Venetian Glassworking – http://renvenetian.cmog.org – presents 35 complete reconstructions of Venetian glassmaking techniques through detailed 360˚ photography and high-definition video.
