Platinum or Platinum Alloy scrap bar - 2.6 grams The bar is approximately 37 mm long (slightly longer if flattened), 12 mm , and 0.5 mm The rod is not stamped but I suspected from its weight and finish that it might be platinum or a platinum alloy The bar weighs 2.623 grams Suspending the bar in distilled water yielded a weight of 0.136 grams for the displaced water, indicating a specific gravity for the bar of 19.29 I weighed the platinum bar on a DigiWeigh DW-BX, 600 gram scale which the manufacturer represents to be accurate within 1/10 of a gram For example, my scale may show a weight of 3.0 grams for a given sample 56mm long, 8mm diamter 1.6ml available
