Finer than ordinary casting sand, it produces \u003cstrong\u003esharp, highly detailed castings\u003c\/strong\u003e in gold, silver, copper-based alloys, pewter, and more—with minimal cleanup. Because the process is cold-molding, you can use patterns made from wood, wax, epoxy, plastics, or metal. The clay can be \u003cstrong\u003ereused\u003c\/strong\u003e after casting, and, as with all sand casting, it excels on parts without pronounced undercuts.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eExceptional detail:\u003c\/strong\u003e Fine grain captures crisp lines and textures.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLess finishing:\u003c\/strong\u003e Clean casts reduce filing and polishing time.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReusable medium:\u003c\/strong\u003e Clay can be reclaimed and used again after casting.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible patterns:\u003c\/strong\u003e Compatible with wood, wax, epoxy, plastics, and metal masters.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTypical Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eJewelry components in gold, silver, and copper alloys\u003c\/li\u003e\n\u003cli\u003eButtons, badges, small hardware, and decorative elements\u003c\/li\u003e\n\u003cli\u003ePewter items and low-melt prototypes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eBasic Process\u003c\/h3\u003e\u003col\u003e\n\u003cli\u003eFill and compact clay into one half of the aluminum ring frame; strike off excess.\u003c\/li\u003e\n\u003cli\u003ePress your pattern halfway into the clay; dust the surface with talcum powder.\u003c\/li\u003e\n\u003cli\u003eInstall the second half of the ring, fill with clay, and compact.\u003c\/li\u003e\n\u003cli\u003eOpen the frame and remove the pattern; cut a \u003cstrong\u003esprue (pouring channel)\u003c\/strong\u003e and \u003cstrong\u003events\u003c\/strong\u003e.\u003c\/li\u003e\n\u003cli\u003eClose the mold and pour molten metal.\u003c\/li\u003e\n\u003c\/ol\u003e\u003ch3\u003eWhat's Included\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003ePart #\u003c\/th\u003e\n\u003cth\u003eItem\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e122.942\u003c\/td\u003e\n\u003ctd\u003eDelft 60 mm Two-Part Aluminum Mold Frame (ring frame)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e122.946\u003c\/td\u003e\n\u003ctd\u003eDelft Clay, 4.4 lb (2 kg) bag\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eNotes\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eBest for designs without deep undercuts, as with any sand-casting process.\u003c\/li\u003e\n\u003cli\u003eDry, oil-free patterns release best; use talc for clean separation.\u003c\/li\u003e\n\u003cli\u003eAlways follow proper foundry safety: eye and hand protection, ventilation, and appropriate casting temperatures.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Otto Frei","offers":[{"title":"Default Title","offer_id":43536296313046,"sku":"122.940","price":95.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/delft-clay-casting-kit-otto-frei.jpg?v=1719959169","url":"https:\/\/www.ottofrei.com\/products\/delft-clay-casting-kit-60mm","provider":"Otto Frei","version":"1.0","type":"link"}
