"Marriage of metals" is a technique where you solder pieces of metal together to make a sheet, and then use that sheet to create something else. If you're good at sawing and measuring, you can make intricate puzzle pieces with the different colors of metals. Or, you can do what I did many years ago, and just work with straight lines. You can click on this photo for a bigger version, the metals in question are sterling silver and brass. Truth be told, I did a pretty bad job on this. It's very important to keep all the pieces flat, which I didn't do very well. And I also used too much solder. Waaaaaay too much.

Blobs of solder can be sanded off, but gaps can't be fixed as easily. I guess I could try to re-flow the solder, but I fear the more I fuss with this, the more problems I'll create. And in one or two spots, an extra bit of solder (shudder) might be needed — and that's where the age of this sheet comes in. I'm sure I was smart enough to use Hard solder when I first made this, but I have no idea which "brand" of solder I used. Since it's likely that every refinery creates a slightly different mix for solder, I'd really be taking a big chance that the old and new solders would flow at slightly different temperatures, which would make an even bigger mess of the sheet.
Not to worry, since it's relatively easy to sand a small piece of the sheet so it's flat and pretty. Here's a ring I made a few weeks ago.
I plan to make more of these rings, but unfortunately, numbers 2 and 3 didn't work out so well.

I'm not exactly sure what happened. I used Easy solder to attach the ring shank to the shapes cut from my big marriage of metals sheet, so you wouldn't think that the Hard joins would melt — at least, not on
both numbers 2 and 3, since I didn't solder them both at the same time. That's some pretty bad luck. Plus, ring number 1 worked very easily. The only thing I can think of is that I rested the shapes on a regular old fire brick for numbers 2 and 3. I don't remember what I used for number 1, but it's possible (and possibly even likely) that I used a solderite board. Although I don't know for sure, the heat properties are probably different.
So I'll use a solderite board for ring number 4. If that doesn't work, I suppose I'll have to re-think everything.
Any ideas?
