The ideal petrobond casting sand alternative, capturing sub-millimeter detail green sand cannot.\u003c\/li\u003e\n\u003cli\u003eOPEN AND USE — NO MIXING, NO MEASURING, NO WATER | Pre-mixed at the factory and shipped ready to pack. Knead by hand for 1–2 minutes to loosen shipping compaction, then ram into your flask and cast. Skip the messy water-mixing green sand requires.\u003c\/li\u003e\n\u003cli\u003eSUPERIOR CASTING CLAY ALTERNATIVE \u0026amp; SAND FOR CASTING JEWELRY | Outperforms delft clay for ring shanks, pendants, signets, and small silver casting work.

When dry, add a few drops of synthetic non-detergent 2-cycle oil and re-knead. Sealed shelf life: 12 months.\u003c\/li\u003e\n\u003cli\u003eVERSATILE SAND FOR MAKING MOLDS WITH ANY PATTERN | Works with metal, wood, plaster, resin, and 3D-printed patterns.
