Even though expensive, I like the five pound, heavy,heat sealed, zip lock bags. They allow me to store it without it absorbing moisture as I don't cast as often these days. The investment worked great! Nice bright silver castings using at least 50% fresh metal and flux with a neutral or reducing flame when casting.

Says it can be used with silver but all of my castings have came out black with this. That’s because this investment powder created sulpher dioxide and instantly tarnishes the silver.
