Technical Information

Glass is a unique material that presents many possibilities to designers and engineers, as well as to artists. Many of the unique possibilities that come with this material often are coupled with a large set of limitations. Part of truly being able to control this material, for both artists and engineers, is to understand, the often complex processes involved in the heating, forming, and cooling of this material.

Physical Properties Involved in Lampworking

Gravity and Surface Tension
Physical properties involved in the forming of molten glass.
Proper Spinning Technique
Necessary to evenly distribute the effects of gravity on the piece.
Heat Base
An even distribution of heat. Heat base allows for symmetrical blowing and forming. If glass is allowed to cool slightly before forming, the heat will start to even out, allowing for more balanced forms.
