Bottle slumping clay mould

To make an successful slumped bottle, you have to make a mould to hold the bottle so it will keep its shape.

Equipment:

• Rolling pin
• Water pot 
• Mat 
• Knife and Fork 
• Clay that is a plastic consistency 

1. Cover the glass bottle in paper towels and use masking tape to keep them stuck to the bottle, this means that the glass bottle wont stick to the clay.
2. Take the clay slab, and flatten it out. Keep turning the slab over as you flatten it out roll it out till it is about 1cm thick.
3. Trim the edges with the knife so you have a long flat oval shape. With the scraps of clay roll 2 fat sausage shapes, stick them to the bottle so it doesn't roll.
4. Drape the clay slab over the bottle and shape around it.
5. Make 4 cross hatching marks on the slab, roll up 4 more balls from the scrap clay and cross hatch them. Add the slip (water) and stick them onto mould.
6. Leave the mould for a couple off days to go bone dry.
7. Put the bottle and the mould into the kiln at 1100 degrees.
