Custom Wood Turn Molds

The Way Wood Works

When the hot glass touches the wet wood, it forms a cushion of steam inside the mold.  The glass rides on the steam, producing a smooth finish.  Vents provide a release for the excess steam and greater control of the form.

 

Punty Set Up vs. Hot Popping/Cold Working

The Two Main Ways to Skin a Cat

This is usually the first question we ask about the design of a mold. 

Punty

This set up assumes the piece will be transferred to the punty and opened to its final shape with jacks.  The open end is reduced in the throat for good back pressure.  Excellent for stretching lip wraps thin. 

Hot Popping/Cold Working

This set up is for open ends that need more precision, such as lamp shades with fitters or glassware with a ground lip.  It's also good for controlling the thickness of the edge.

The bottom of the form has a concavity, such as the punt of a wine bottle.  Care must be taken that the form can be released once blown.
