i have been using craft casting expoxy and its been doing fine. now i am starting to do a little more , sugestions on something that i can get in a little larger size , that would have a long shelf life.
most of the casting i have been doing has been coffee bean and crushed coal. i have been using some powder coat paint for die / color.
thanks
David

alumnite or silmar 41 from uscomposites
you'd need pressure for both i believe when using coffee beans

I'll second the Silmar 41, if for no other reason than that many other people
here are using it. When they give hints or advice, you can be pretty
sure you'll be comparing apples to apples.
And, it works well for what we're doing.

Pressure is not needed with PR for coffee beans. But be ready to fill in where the beans have bubbles or gaps.
