Dr. Who Sonic Screwdriver Pendant in Sterling Silver or Antique Bronze
For all the fans of Dr. Who in my life, I made a small sonic screwdriver pendant available in sterling silver or antique bronze! It is based on the 11th Dr's. The pendant is 1 1/2 inch long and 1/4 inch wide. Thank the Dalek that threatened to exterminate me in order for me to make it!!!
Sterling silver is an alloy of silver containing 92.5% by weight of silver and 7.5% by weight of copper. The sterling silver standard has a minimum millesimal fineness of 925.
Bronze is an alloy that consists of a mixture of approximately 90% copper and 10% tin. Producing bronze is a less toxic process than producing brass as brass is a combination of copper and zinc, and the manufacturing process often produces zinc oxide which is toxic.
Because bronze contains copper, it can turn your skin green whether you have an allergy or not. Bronze and copper turn your skin green because when the copper reacts with your sweat and the acids from your skin, it produces copper chloride. Copper chloride is a green substance that then rubs off on your skin. If you are prone to sweating, your bronze jewelry will definitely turn your skin green. This chemical reaction can also be prevented by painting any part of the jewelry that comes in contact with your skin with clear nail polish or clear acrylic enamel.
