The Chavagnes gladiators cup, made in the mid-first century A.D., was found in eastern France, and it is now part of the Corning collection. It shows pairs of gladiators in combat, and some of their names are known from literary and epigraphic sources. This sports cup, blown in a mold with two vertical sections, would presumably have been modestly priced and intended for the mass market. This video shows mold blowing, the addition of handles, and cracking off.

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.
