From Clay to Creation: The Slip Casting Process

Have you ever wondered how a beautiful ceramic piece comes to life? Behind every finished piece is a process that takes creativity, patience and a little bit of magic.

Hannah and Jean at Ballymorris Pottery have recently been busy slip casting. A peek behind the scenes at the pottery, shows the fascinating process of slip casting using their very own unique designs, some of which started life as hand-sculpted creations.

Every design starts somewhere

Before a piece can be cast, there's the original design. Some of the pottery's creations begin as carefully sculpted models, each one shaped by hand and carrying its own little personality. These original designs are then used to create plaster moulds, allowing the pottery to reproduce the pieces while retaining all those lovely details.

The art of slip casting

This is where things get interesting!

Liquid clay, known as casting slip, is poured into specially made plaster moulds. The plaster gradually absorbs moisture from the clay, allowing a layer of clay to build up against the inside of the mould.

Once the clay has reached the desired thickness, the excess slip is poured away and the mould is left to rest.

It might look like a fairly straightforward process, but there's a real skill involved in knowing when the clay is ready and how to handle each stage.

The big reveal

One of our favourite parts was returning the following day to see the moulds being opened.

Carefully separating the plaster sections reveals the newly formed clay pieces, still delicate at this stage and needing a gentle touch. It's such a lovely moment – seeing a design emerge from its mould, with all those little details finally taking shape.

From the original sculpture to the first reveal, it's fascinating to see how much thought and craftsmanship goes into each creation.

And this is only the beginning! The pieces still have drying, finishing and firing ahead of them before they're ready for their next chapter.

There's something rather special about seeing the making process up close. It gives you a whole new appreciation for the creativity and hands-on work behind every ceramic piece.
