a chat with Andrew Quitmeyer (the King of Silicon MIX!):

Andrew Quitmeyer > corn starch is nice, glycerin or acrylic paint packdown lighter for travelling with.
(ive heard the cornstarch works because it uses the like glycerin fat in the corn starch). Cover your hands with coconut oil and you can manipulate the silicone like play dough!

idiot.io > what about avocado oil? can’t stand coco smell..:]

Andrew Quitmeyer > yeah man try it! i bet it works! some oils will fuck with the silicone(not cure), and some will never leave and stay sticky or oily, so it does depend on the oil, but so far mineral and coconut work great!

Good luck and keep me posted how it goes! another nice thing about non-cornstarch mixes is that cornstarch can sometimes stick to the things you are molding in it, the cornstarch can become brittle, you can get pockets of over-dense cornstarch, and it can change the texture sometimes for fine details.a

I really want to find a cheap, portable way to do food-safe as well. Only things i can find “food safe” are smooth on silicones, and they are expensive and hard to travel with.

idiot.io > is there a way to get rid of the acetone inside the silicon burn it away or somthing? like after we make the mold?

idiot.io > you should make a mold making machine with your robotic arm in a pile of corn starch… thats the best cheap foodgrade so far..

Andrew Quitmeyer > it’s not acetone, it’s acetic acid (vinegar) which sort of fully evaporates after about 3 days so that’s why it makes your pops sour, but not necessarily toxic! BUT some types of caulk include slight bits of anti-fungal chemicals too, which can probably not be super great for humans

idiot.io > ok it does smell like vinegar in horrible waves..

idiot.io > it is possible to cook it in a oven for lil bit and get rid of all the trouble?

Andrew Quitmeyer > yeah low temp oven cooking is good for them!

idiot.io > much thanks the king of silicon mix!!
