All the pottery and sculpture
I produce is high fired and lead
free stoneware and porcelain. My
kiln is fired to 2400 degrees
with propane, and the firing
takes a full day.
 Each
piece is fired twice. The first
firing is in an electric kiln,
to dry out the water out of the
clay and to harden it for
glazing. This is the bisque
firing.
Glazes are finely ground
minerals that when heated melt
and form a glass on the surface
of bisque fired pottery. Each
glaze has different minerals for
variety in surface texture and
color. Glazes look much
different before and after the
firing. At this high temperature
the clay becomes vitreous and
will hold water, even without
glaze. Glaze adds another hard
permanent layer of decoration
and strength.
