Not sure - something to do with molten aluminium and too much water content not being a good mix - - best place would be to check the H&S data that your LA supplies. We find it much easier because you don't have to worry about mixing and getting the consistencey just right.

Thanks for the comment but there is no warer in the sand. It is oiled sand. Using water in sand in schools hasn't been the norm for a while because of the safey implications and getting the correct water /sand content.

i would appreciate if someone posted the composition of green sand, or even better, a way to make your own at home.
ich wäre dankbar wenn jemand die zusammensetzung des sandes verrät, oder noch besser, wie man den selbst zuhause machen kann

The sand we use is called petrabond sand and is oiled sand. It is available in 25Kg bags from suppliers in the UK for about £25
