I'm surprised how quickly young kids pick up on the name. It's like a second language to them. Must be the texting they all do.

This is a type of engraving and/or forming of a copper alloy. Have you tried anything like this? I have been wanting to try casting the copper discs, they are traditionally cast in water. Pouring molten copper into a water bath sounds scary but I've seen it done and it works. It makes the copper very small grained and it engraves almost like gold. I don't plan on doing the engraving, I'm making the disc for a friend of mine.

Could you imagine doing something like this with a CNC?

It would have to be old pennies, pre 1982. Some of the alloys for this have a small amount of Silver or Gold in them. I'll try some with a little Tin first and see how it goes, I doubt if I ever try gold since it's gone through the roof. Although I do have several sheets of gold leaf, I don't think it's enough for the alloy. The gold/copper alloy is supposed to turn a jet black with oxidation. I think the silver is more of a brown color.

Well, I found out yesterday that I can't melt copper in my electric furnace. Probably isn't a good idea to melt brass in it. I got the copper up to 1800F and the elements broke. When I checked it and the whole element crumbled to little pieces. I'll rewire it and then keep it below 1250F for aluminum and pewter.
I'll have to get the propane furnace out and finish this melt.
I started a melt with 90% copper, 10% tin, and a small amount of copper/phos rod to alleviate gas issues. I had the water bath all set up, too. Maybe next week.

Sorry to hear you electric furnace broke, I always thought that the temps needed to melt metal was left to gas.

there are several videos worth watching about this art and his methods.

I've been following his stuff for a few months, he has a pretty large gallery of things he's done. That is some beautiful engravings. I don't think I have the patience or that my neck could handle bending over the bench.

Wow, that should keep me busy for a while, Need to take the laptop to the "Throne Room". I had started setting up an engraving table to cut some printing plates...Not For Dollar bills! Still may try that some time, but I need a mill of some kind to make perfectly flat blanks. I've got too many hobbies.

I may be away for a while, we are going into Move mode. Sold our house and need to find a place...soon. I had just decided to settle in for winter, now I've got to get out before winter sets in. I'll let you know where we end up. Hopefully Chattanooga area, a little warmer and some good fishing.
Everyone be safe, I'll be around.
