This
technique ensures that there is no need to hollow out afterwards.
Air and water can get trapped during firing if the clay is thicker
than an inch, resulting in cracks or sometimes exploding pots.
Firing
Sculptures are fired to 1240 C in an electric kiln. The detail is
highlighted with a metal oxide that is brushed on, and then sponged
off. Glaze stains are used as colourants, both during the making,
and during glazing. Brendan uses as little glaze as possible, and
will often seal the surface with wax, after firing, rather than
risk loosing the detail by applying a glaze.
