Technical Post - Sculpting & Preparation

This week we have begun to sculpt our clay shapes so we can then make our silicone moulds. I found the clay quite difficult to work with at first but once it starts to warm up it's quite simple

You will need:

Clay

Hairdryer

Sculpt tools

Spatulas

Plastic Square

Plastic cups

Fixer spray

IPA

Gel 25 Silicone – A,B & C

Digital Scales

Wooden spatulas

• Cut a square of plastic out to carve your mould onto, make it as big as you would like as long as it’s big enough for the shape you create
• Blow a warm hairdryer onto the clay to make it easier to cut some off and start moulding your shape on the plastic
• Make sure your edges go flatter towards the edge, this is so the mould isn’t too think and will make it easier when stick the silicone piece onto the skin
• It’s best to get the clay as smooth as possible so the silicone is smooth too, use a spatula or your fingers to do this
• Once your happy with it clean it with some IPA to get rid of any dirt or bits of hair that might be on there and spray with fixer spray
• Then cut the bottom off a plastic cup and glue gun it onto the square around the clay, this will stop any silicone from coming out from under the cup when you pour it in
• You need to measure out 75 grams of part A and 75 grams of part B on your scales into separate cups, it's important you do not contaminate the tubs so use different spatulas and gloves for this reason as it can stop the product from working
• Make sure they weigh exactly the same and then mix them together thoroughly, you can then pour the mixture into your cup covering the clay
