Charlotte D. ★★★★★

I’ve been battling tiny bubbles in my metal castings for months, but a light dusting of this talc before pouring really settled the mold flow and cut the pinholes way down. The jar is small but it goes a long way—just a pinch on the pattern makes the epoxy putty release cleanly without sticking. Def

John I. ★★★★★

This tiny jar completely solved my epoxy putty sticking to the mold surface. I tap just a little powder into the cavity and the detail fills perfectly without any trapped air. Mold durability also seems improved after the first few pours.

Grace ★★★★★

Switching from baby powder to this talc was a game-changer for my silicone molds. The 2 oz jar lasts through multiple pours, and the way it helps the metal flow into those tiny details is impressive.
