The extra strength makes it the ideal choice for designs taking a lot of wear and tear, fingerprint jewellery, as well as rings, cuffs, and delicate thin open-ended designs.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWHAT DOES 950 STAND FOR? \u003c\/strong\u003e\u003cbr\u003e950 is the purity of the silver after firing; 95% silver and 5% copper. The ACS950 will be hallmarked as Sterling silver in the UK. \u003cem\u003eIn the UK, silver up to 958 purity is hallmarked as Sterling silver (925). Silver purity over 958 is considered Britannia silver (958), and over 990 is hallmarked as Fine silver (999).\u003c\/em\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSHRINKAGE\u003c\/strong\u003e\u003cbr\u003eThe ACS950 shrinks about 10-13%, so slightly more than the regular Art Clay Silver (which shrinks about 8-10%).
