{"product_id":"jewelry-investment-plaster-lost-wax-93795","title":"Jewelry Investment Plaster | Lost Wax Casting Powder","description":"\u003cp\u003eLost-wax casting is one of metalworking’s oldest acts of transformation. For thousands of years, makers have shaped temporary forms in wax, surrounded them with heat-resistant material, burned the wax away, and poured molten metal into the space left behind. The tools have changed. The craft is still the same. \u003c\/p\u003e\n\u003cp\u003eModern jewelry investment powder is the refined version of that ancient mold material. Gypsum-bonded investment combines a plaster-based binder with refractory mineral components engineered to withstand burnout temperatures while expanding in a controlled way around fine detail. Mixed with water, it becomes a smooth slurry that flows around carved wax or castable patterns, hardens into a rigid flask, and preserves the negative space that becomes the final metal object.\u003c\/p\u003e\n\u003cp\u003eThis investment powder is intended for lost-wax jewelry casting molds, including rings, pendants, settings, charms, and other small metalwork. Accurate water ratios, thorough mixing, vacuuming, curing, and a controlled burnout schedule all contribute to clean detail and consistent surface quality.\u003c\/p\u003e\n\u003cp\u003eOffered in smaller bench-scale quantities for makers who do not need a full commercial bag.\u003c\/p\u003e\n\u003cp\u003eSelect Size at Checkout\u003c\/p\u003e\n\u003cp\u003e1 lb \/ 453 g\u003cbr\u003e\n2 lb \/ 907 g\u003c\/p\u003e\n\u003cp\u003eRepacked from bulk commercial supply\u003cbr\u003e\nFor the Modern Maker\u003c\/p\u003e\n\u003cp\u003eShips from the Pacific Northwest, USA\u003c\/p\u003e\n\u003cp\u003eEvery order supports Aetherium Innovations and our mission to develop tools and technologies that lower the barriers in the skilled art trades.\u003c\/p\u003e","brand":"Aetherium Innovations","offers":[{"title":"1lb (453gr)","offer_id":45874009243783,"sku":null,"price":26.0,"currency_code":"USD","in_stock":true},{"title":"2lb (907gr)","offer_id":45874009276551,"sku":null,"price":36.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0641\/7062\/3111\/files\/il_fullxfull.8583124971_32qy.jpg?v=1789615396","url":"https:\/\/aetheriuminnovations.com\/products\/jewelry-investment-plaster-lost-wax-93795","provider":"Aetherium Innovations","version":"1.0","type":"link"}
