If you were going to cast your own dollies/armatures, what is the highest temperature that metal would need to resist in the mold-making process? Jeff |

if you use these low temp silicone moulds then about 90 deg.
i have vulcanised resin, plastic and metal parts in low temp silicone with no problems.
if using the black organic moulds then about twice that temp if i remember rightly.
can you vulcanise it yourself or are you looking to get someone else to do it?

I'm just looking to drop cast dollies for myself (to help keep all my proprtions in line, and save a bit of time). I assume you're using celcius, Shaun? So the armature for a sculpt in black organic molds would need to have a melt temp in excess of 180c to be viable? |

i have seen moulds made in black from whiote metal masters and as the melting point for what a lot of us use is higher than the rubber vulcanising point you should be ok.
the trouble with drop casting is getting it in all of the extremities.
good luck |
