Experimenting with new mould making technique
So, I am attempting to make a ‘mother first’ or ‘pour technique’ mould for pewter casting.
I have made a wax sculpture of an 8 week old embryo – life size i.e. 1 1/2 inch long. This is going to be the centre of a sculpture about embryo development.
I want to cast it in Pewter, to then be able to cast a number and try out some different ideas for the sculpture.
I am using RTV101 silicon rubber from Tirantis that will take the heat of the molten pewter. And I’m using a new technique that I learnt at the foundry on my last visit. However, the embryo is a tricky shape with lots of undercuts, so I’m trying to do a mould with a rubber cap – I hope it will work.
