hello my fellow casters im just starting my foundry casting up again after a 17 year break when i used to cast lead soldiers now ive grown up im gonna try casting some engine bases but im haveing trouble with my sand it is ancient foundry sand i scuppered from a foundry being torn down the sand itself is black as coal verry coarse and doesent hold solid enough and a 90 year old geezer down the street tells me i need bentonite clay and can obtain this by grinding kitty litter is this true because i cant find it in any animal feed supplier and ive no hope of finding a pottery supplier round these parts and most civil engineers i know have never heared of the stuff
is it possible or am i just gonna ruin my 200kg foundry sand rescue
