Calcium Carbonate 0.8kg – Parting Powder for Metal Casting
This listing is for one (1) 0.8 kg Bag of
Calcium Carbonate manufactures by Omya Australia

So here they are.
I used talcum powder for a while but this works so much better. Even if I mix the green sand a bit wet it still make both halves of the mold and pattern release.
