If I try a lost wax style setup with Sodium Silicate sand and I can’t heat it to melt out the pattern maybe I could make the pattern from urethane foam and dissolve it out with a solvent. If I used Acetone and soaked the mold in it that would make for an exciting pour. I could just pour the aluminum into the mold and let the foam melt out. I think Toyota makes cylinder heads this way. Saw a You Tube on that.
