Hello - I am trying to make a transparent mould from a very detailed piece of silicone so that I can ultimately cast with my alumilite amazing clear. I am struggling to get a capable material. I thought about casting a mould with either plaster of paris or mold putty - but I am concerned re air pockets, added textures and with the negative being so flexible I'm not sure I'll get an even/level mould - nor am I sure that I'll be able to turn out the alumilite from either of these even if I manage this far? Is there a liquid mold putty available that will accomodate the above?
I should point out that this is a flat lay mould with detail on 1 side only.
One of the Plat series or Trans 40 would work for what you want. Just be aware that the Plat is a platinum silicone so it is a little "funny" about what it cures around so read what can inhibit curing for it. I haven't used the Trans 40 yet but I expect it would work the same as the Plat on the inhibiting the curing.
