Dunoon Making Process:
1. Making plaster moulds:
Plaster and water are mixed in a jug to a set ratio. The mix is pure into rubber cases and allowed to set.
2. Making slip:
Clay is mixed with water to form a suspension known as slip.
3. Filling the moulds with slip:
The slip is poured into moulds on the casting process. The moulds travel to the end of the casting belt in about five minutes.
4. Tipping the excess slip:
The excess slip is poured our and the mould allowed to drain.
5. Opening the moulds
The moulds are opened and the soft clay mug is taken out
6. Sponging the clay mug:
The dry clay mug is sponged by hand to remove any imperfections.
7. Handle casting:
The hands are cast in a similar manner to the mugs in a two-part mould.
8. Sticking the handle:
The handle is dabbed into the slip and applied to the mug body by hand. The excess slip from around the handle joint is wiped away with a sponge.
9. Placing & firing the clay mug:
The clay mugs are placed onto kiln cars which are wheeled into & out of the kiln.
10. Biscuit kiln:
