I generally use a heavily grogged crank clay, especially for my garden sculptures. This
type of clay has the rough, natural feel that I am looking for. I hand
build all of my pieces by rolling a slab of clay and then building the
shape that I want. To get the surface design I use naturally found
tools such as stones, shells and twigs found on local fells and
beaches. I then use my fingers to add a unique fingerprint to my
pieces. The use of natural objects to make the surface design adds a
dimension not evident in other ceramics. Once
the form is created it has to stand for a week or so until the clay
goes 'leather hard'. When the clay is leather hard, the pieces
are 'biscuit fired' at 800oC,
which completely dries the clay and prepares the surface for glazing.
During the biscuit firing, the pieces can shrink by up to 10% in
volume. For surface colouring I use natural earth oxides, such as
rutile, iron and vanadium, and then a matt light-oatmeal glaze. Once
glazed I fire my work to 'stoneware' or 1280oC, which makes the clay completely non-porus and frost proof. Although
I appreciate the skill in producing neat and tidy pieces, I actually
like my ceramics left with a rough appearance due to my unconventional
approach to slab rolling, hand building and mark making. I choose not to produce thrown forms but if I did, I would end up altering them to make them appear dishevelled and aged! You will see that the results of my work is an edgy, raw, robust form combined with rustic natural elements.
