"Kilncarving" is a term coined at Bullseye to describe
a simple kilnforming process that achieves a bas relief,
textured, or sculpted look in glass. The process involves
cutting a pattern or design in ceramic fiber paper, then
stacking glass on top of the pattern and firing the piece in
a kiln. During firing, the underside of the glass conforms to
the ceramic fiber paper pattern, assuming its contours and
Kilncarving is a good beginning technique. In trying
it, you can learn how glass reacts with heat at various
temperatures, and you can achieve some beautiful shapes
and patterns with only minimal glass cutting and fusing.
The two primary materials used in this process are glass
and ceramic fiber paper. The primary tool - besides a
kiln - is an X-Acto knife. In this TipSheet, we provide some
basic information about the materials, tools, and steps
involved in kilncarving glass.
