Copper cleaning

[del]

Very nice tips ! I like the use of the high watt light. Never heard of this one.

Yeah those high wattage flood lamps work well , they can actually get the coin hot to the touch and speed up the drying and flaking of the crusty dirt.

You're clearly an expert. Look at that video. Scalpel on roman coins. I'm sure you'll like it

I would never consider myself an "expert" by any means just been cleaning these coins for more than 15 years now . I would never use a scalpel but some of the steel picks are very sharp and I do use them in the same way at times. I wish our copper cons held up as well as those old Roman bronze ones did . Thanks for the video .
