PRODUCT INFO
As green sand is used to cast metal the bentonite clay touching the molten metal loses binding strength. If a refresh is not performed the green sand will begin losing noticable strength.
Simply adding a little new bentonite will refresh the sand and help maintain the strength.
Our bentonite is 300 mesh western bentonite
