How to Blow Glass: Making a Simple Cylinder (Cup or Vase)

How to use the wooden Blocks to make a Starter Bubble and make a 2-gather simple cylinder (cup, vase, etc) using a Foot Pedal Pneumatic Blowing System. (How-To-Build Video here:    • Foot-Pedal Pneumatic Glassblowing Sys...   — so you don't have to remove your mask to blow glass during Coronavirus times!)

This demo focuses on continuously thinning the neck-line and shoulder of the bubble using the Marver and the "Drop Heat". Once it's on the Punty we can Tweezer and Trim to thin even further. Also demonstrates the use of the Steam Stick, an old-school glassblowing tool that takes the place of a Soffietta or Puffer. The Steam Stick is kept wet and when inserted into the opening of hot glass the water turns to steam, pressurizing the glass. If the glass is soft enough it inflates to the appropriate shape to open.
