What is Silver Clay?

Silver clay was invented in Japan. The silver is reclaimed from the film and medical industries where it is sometimes a waste product. This industrial waste is reprocessed by a complex system. The silver is extracted out of the waste material and is ground into a fine powder then mixed with organic binders and water. This resulting clay-like material can be shaped, moulded and sculpted into your chosen designs. It progresses through a drying and refining process. When it is kiln, torch or gas hob fired, the binders burn away leaving 99.9% pure silver ready to be hallmarked. Please note that if you want to sell any jewellery that you make using silver clay, then in the UK you are legally required to add your hallmark to any item weighing 7.78gm or more. Further information is available in the Hallmarking page.
