How Much is Your Scrap Nickel Worth?
The Scrap Nickel Melt Value Calculator, shown below, can figure the total nickelvalue of scrap nickel items, measured by the weight unit of your choice. The nickelvalue is figured based on the total amount of actual nickel content, not includingany other metals used if the nickel is an alloy. The scrap nickel calculator will only showwhat the nickel is worth (intrinsic value), and not any collectible value of yournickel items.
Abrasives and polishing
For an abrasive to remove material from a metal surface, the abrasive must be harder than the surface (Samuels 2003). Silver sulfide, the main component of tarnish on silver, is only slightly softer than silver metal; there is no abrasive with just the right hardness to remove the tarnish but not the metal. Calcium carbonate (CaCO3), only slightly harder than either silver or silver sulfide, is considered to be a gentle abrasive, but it is still hard enough to scratch the silver surface (Wharton et al. 1990).
Acrylic is about as hard as silver and silver tarnish, making it a convenient material to use for testing a polish.
