Streaming live on Facebook, tune in for a glassblowing demonstration! We'll be blowing glass live at 6pm demonstrating the difficult Venetian Encalmo/Incalmo technique of joining two glass bubbles of different colors together.

This is an impressively tricky technique , as glass colors require different temperatures to work without damage. In order to make an Encalmo piece, glassblowers must work two separate bubbles of glass and then join them together. In order to join the separate parts, glassblowers open the end of each bubble and join them in the flame. The joining is particularly difficult because the lips of both bubbles must be identical sizes to be joined correctly. Teamwork, communication and respect are essential for success.
