ALBANY, N.Y.—A modern-day glassblower believes he has unraveled the mysteries of Renaissance-era Venetian glassmaking, a trade whose secrets were so closely guarded that anyone who divulged them faced the prospect of death.

Today’s glassblowers work with methane-fired furnaces, electric-powered kilns, good lighting, and proper ventilation. The craftsmen of Murano, an island near Venice, didn’t have such technology, yet they still turned out museum-worthy pieces known for their artistry and beauty, using techniques that remained exclusive for centuries.

Through years of researching Venetian glass collections at American and European museums and comparing the artifacts with more contemporary glasswork from Venice, plus his own experimentation and many trips to Italy, William Gudenrath has created an online resource he believes explains Venetian glassmakers’ methods.

“The Techniques of Renaissance Venetian Glassworking”—which contains videos, photographs, and text — details how Gudenrath surmises glassworkers produced works of art with little more than wood-fired furnaces and metal blow pipes and tongs. The information was posted this week on the website of the Corning Museum of Glass in upstate New York, where Gudenrath is a resident adviser and teacher of Venetian techniques.

Yet they mastered the tricky art of glass decoration by continuously reheating and shaping the vessel after the decorations had been added.
