Slip Casting

Slip Casting is central to the majority of shapes we produce here at Aston Pottery. All of
our mugs, jugs and teapots are created using this technique of pouring liquid clay (slip) into plaster
moulds. Timing is crucial, the liquid in the mould dries from the outside in, the excess liquid
is tipped leaving a shape formed by the relief of the mould.


Jiggering and Jollying is the closest to traditional manufacturing techniques
we use at Aston Pottery. Both methods involve a combination of steel tool and
plaster mould working to form the internal and external profiles
of a shape. When Jiggering, the tool creates the outside of a shape, pressing the
clay against the mould that gives form to the inside whilst when Jollying
the roles of tool and mould is reversed.


In contrast to Jiggering and Jollying, Rollering is one of the most modern
manufacturing techniques we employ here. A large metal head is heated to 240 degrees and is
brought down onto the mould. The machine heats and rolls the clay over the
plaster mould forming the desired shape. We use this process for all
our plates and a number of our bowls.


Before their first trip into the kiln our pottery needs to have the rough edges removed,
for the slip cast ware, a seam is also left along the sides where the mould splits open.
The sponging of our products also primes our pottery for decoration as a rough surface greatly
improves the application of our colours.
