鑄造用滑石

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

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.

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.
