摘要
A method for producing silica sand-based foundry shapes useful in forming metal castings and for reducing veining defects in sand-based foundry shapes by providing a foundry sand, adding an anti-veining composition that comprises bentonite to the foundry sand to form a mineral composition, then adding a foundry resin to the mineral composition to form a sand-based foundry composition and shaping the sand-based foundry composition to form a desired pattern.
