How English slipware was made
Many dishes were formed by laying a slab of clay over a convex mould. Once the clay had dried sufficiently to hold its shape, the dish could be removed from the mould and decorated with slip - clay mixed with water to form a liquid that could be poured, brushed or trailed across the surface.
Potters developed a rich vocabulary of slip decoration. Techniques included slip trailing, marbling, sgraffito - in which a design is scratched or incised through a layer of slip - and combing.
Combed slipware is particularly distinctive. Contrasting slips, often in cream and shades of brown, were applied to the surface of the vessel. While still fluid, a pointed implement or comb was drawn through them, pulling the colours together to create rhythmic lines, waves and feathered patterns. The process was relatively straightforward, but small variations in the movement of the potter’s hand ensured that every finished piece was different.
Some dishes were given an additional decorative flourish in the form of a crimped or “pie-crust” rim, lending even an everyday household object a pleasing sense of finish.
Staffordshire and beyond
Slipware is closely associated with Staffordshire, one of the great centres of English pottery production, but it was by no means confined to a single region. Related wares were produced in different parts of Britain, with potters, techniques and decorative ideas travelling between established pottery-making communities.
Local materials were fundamental to their character. The clay body could be sourced relatively close to the pottery, and the warm reds and earthy browns visible on surviving examples are an important part of their visual appeal.
On many dishes, the decorated face is glazed while the reverse remains comparatively plain, revealing the colour and texture of the earthenware body beneath.
