Polytek TinThix Liquid Thickening Agent (.25lb)

I’ve never made a mold before but I was gathering all the supplies I think I needed. This turned out perfectly. Easy to use. Instead of making a mess pouring things, I use a syringe to extract everything. For my small piece, I only needed a drop or two to add into my mixed silicone and viola! Thickened it up like vasaline which was exactly what I was going for. I def recommend.

Works well when making mold but cost a lot for little bottle.
