Ok so there are a lot of different types of silicone. There is tin silicone and there is platinum silicone.
Platinum silicone is the super soft high grade silicone that we use for making our silicone babies, it comes in two parts - part A and part B.
Platinum silicone is very sensitive to certain products and if it comes into contact with these products it will inhibit the cure. The major products to avoid are - Sulphur (sulfur), Latex, and Tin silicone. There are other things that it will sometimes react to unexpectedly. So we need to be very careful we do NOT allow our uncured platinum silicone to come into contact with any of these items.
So as a rule of thumb...
- make sure the clay you are using does not contain sulphur.
- make sure the gloves you use do not contain latex.
- if you use sponges to paint with, make sure they do not contain latex.
- make sure the silicone you use to make your mould is also platinum silicone and NOT tin silicone.
If you are in any doubt as to whether a product can be used (eg some of the wedge sponges are labelled as latex-free but still contain something that inhibits the cure, and some nitrile gloves contain something that is problematic) so if it is the first time you have used a product, better to do a quick test. To do a test, paint some platinum silicone onto the product (eg a sponge or a glove) and leave to cure. If it cures ok, then go ahead and use the product. If it remains tacky or sticky, then don't use it. Simple as that.
I've been sculpting, moulding, pouring and finishing my own dolls for 7 or 8 years now, it's a fairly isolated life filled with clay, tools, and sticky stuff. I am going to be sharing things with you, tips and tricks for making babies as well as some inane ramblings just because that's who I am. Hope you enjoy.
