Learning to "block" a gather of molten glass

Devin Bannister, glass blowing instructor, shows Meghana how to properly shape her gather of molten glass using a cherry wood block.  This is one of several methods of shaping glass and has been used by glass blowers around the world for centuries.  The technique requires practice to be used effectively.

Applying Color

Devin is showing Meghana one technique for applying color to her bubble.  The glass blower can simply sprinkle some colored "frit" on the glass blowing table (called a marver) and roll the hot glass over it.  

Glass blowers must purchase colored glass from suppliers to add color to glass.  It comes in many forms --from powders to pebble-sized pieces to solid one inch rods--depending on the application by the glass artist.  Metal oxides are the primary ingredient in colored glass.

Reheating the Piece in the Glory Hole

Ram is learning how to reheat his glass art piece in the reheat furnace called a "glory hole".  Glory holes run only during production and are generally powered by natural gas or propane.  It can reach temperatures of 2300 degrees.  It is a delicate balance reheating a piece in that it must be softened enough to be further worked or refined but not so much that previous work is not compromised.
