photo Glassblowing


Glass that has melted in a high-temperature furnace is applied to the tip of a stainless steel pipe called a blowpipe. Then the craftsman blows into the pipe and causes the glass to inflate like a balloon, creating various forms. The glass is placed in an annealing furnace, which cools the piece.
In the most common style, free-blowing, air blown into the pipe forms different shapes based on how the pipe is moved or blown. In mold-blowing, glass is blown into a wood or metal mold, and large amounts of the same form can be created. The shape or thickness of glass creates beautiful variations in transparency and light refraction. Combinations of clear and colored glass produce charming results as well.


  1. 1.A blowpipe is dipped into molten glass to remove a blob of it from a furnace.
  2. 2.The blob of glass is inflated into a large shape through blowing into the pipe.
  3. 3.Diamond shears are used to rotate and expand the shape.
  4. 4.A pair of tongs are used to put finishing touches on the glass. Then it is slowly cooled in an annealing furnace.
