Sap Moderator Australia 16804 Posts	Posted 11/08/2023 5:35 pm "Tarnish" is the formation of silver sulfide. Whether a silver coin turns black or not depends on the environment in which it was stored: if there's lots of sulfur in the air, it will turn black. Sulfur can come from various sources: air pollution, certain types of cardboard, most types of rubber, and fumes from cooking with eggs garlic or onions, are some common examples. Put a silver coin in a sealed box with a source of sulfur, and the coin will turn black in just a few weeks. Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis Report this Post to the Staff
