Here is a useful and VERY low toxicity metal alloy composed of Indium and Bismuth exclusively, with no lead, cadmium, tin, antimony, zinc or mercury, and it melts at 70.9°C and liquefies completely at temperatures above 165°F/75°C. This very low melting point means it can be easily melted in a pot of boiling water or else with a very small and low wattage soldering iron and be used to seal plastic, glass or metal items that have a lip to mold over and bind with much more strength than waxes, plastics or adhesives. This seal can then be rewetted or broken again simply by using a pot of boiling water or else a very low wattage soldering tool. This alloy lends itself to a wide range of experimentation by the Material Sciences Engineer for specialized applications and usage.  This auction is for 20 GRAMS IN A SINGLE ROUND INGOT. There is no restriction on transportation or use of this material since both Indium and Bismuth are environmentally safe elements. The amazing thing is that Bismuth alone melts at over 520°F and Indium at over 311°F. This sampling was made using very high purity components and fractionally solidified over 30X yielding an extremely high purity of 5N - 99.999% Indium-Bismuth Eutectic Alloy. Acceptable forms of payment are: PAYPAL or PERSONAL or COMPANY CHECKS or MONEY ORDERS.  Shipping to the 50 states is $6.95 and $8.95 to Canada and $18.00 to U.K. and Europe and Australia (which includes Registered Mail). This item may NOT be combined with any other auction concurrently running for reduced shipment costs so please be so advised.  You MUST HAVE AT LEAST 10 POSITIVE FEEDBACKS to bid on this auction unless you contact me prior to your placing a bid with YOUR NAME and ADDRESS and PHONE NUMBER.
