Despite the cooler overnight temperatures, the resin I poured yesterday did kick over night. I was using Smooth-Cast 326 without tint, so the casts made under pressure are completely transparent. It's a neat effect, but for the next round of casts I will be adding material. The original parts I molded were metal, and so I am looking forward to cold casting my replicas with aluminum powder from Smooth-On.
I'll be posting photos of the finished casts later this weekend.
