• Once your sure the silicone is hardened you can take the cup off using scissors and it should come apart quite easily, it will come away from the clay too then clean with IPA
• Spray the mould with petroleaze and then using a mixture of 1 part acetone and 2 parts baldiez brush on around 3 layers to the mould making sure there dry in between each layer
• You can now measure your silicone to pour into the mould, 50% A & 50% B then 90% C
• Mix them all together and add a small pea sized amount of colour and mix well
• Put your mould on a flat surface and pour in the silicone, use a ruler or spatula to scrape off the excess so it doesn't over spill
• Take some nepatha on a cotton bud and clean around the mould to get rid of excess silicone, this doesn't melt away the baldiez and acetone mixture
• Leave to dry, powder with baby powder once your sure its dry to take away stickiness
