High Fired Glass

Fusing a high fired glass pendant at high temperature with colored frit powder to create an abstract design. The piece is taken up to a high temperature to create the color variations seen on the pendant.

High temperature causes color shifts and the colors to run. Care needs to be taken with this process to ensure the kiln does not overheat.

The glass should be monitored, as bubbles just below the surface will sometimes appear at high temperature.

This painted pendant has been colored using some of the techniques found on the glass powder painting page.

High fired items can be made in a variety of shapes and colors. System 96 products have been used for this project.

White glass has been used for the pendant but other colors can be used to deepen the powder colors. Clear or transparent colored glasses can also be used to create very original designs.

The paint techniques used can be modified to suit you tastes, the powder for this pendant was applied with cocktail sticks. Mixed powder can be applied from small squeeze bottles and swirled on the surface with a paint brush.
