Dug a few pennies and half pennies off the beach on the weekend that were totally trashed by dreaded green fluff.
I know there’s a fairly rough way of killing it (at the expense of the coins appearance) by heating them in the oven.
Well, I was at work, was curious, and didn’t have an oven.
I do, however, have a kiln. I’ll stick them in there and just pull them out once they’ve hit the 200° mark.
Long story short, I got distracted, forgot about them and went home.
Came in this morning, saw the kiln had completed the cycle and after a bit of trepidation I opened the door…
Ladies and Gentlemen, I present to you - buggered bronzes
You too can do this to your collection by heating gently to 1088°C for two hours.
Well, it killed the fungus!!!
