Am I the only one who takes pleasure in breaking a copper pipe in half at -40 celcius?
Either way, German Dark is produced by integrating unburned carbons into a thin, easily heat-softened layer of aluminum foil in an inert atmosphere where the carbons aren't completely burned.
I am not sure if one could create a device with two pieces of enclosed sheet metal and put a layer of tin foil with two pieces of paper in between them, putting them over a very hot fire for a while, but that'd be an interesting experiment to undertake nonetheless.
I have made lampblacked aluminum before that can be practically lit with a match but it is still nowhere near the quality of authentic dark aluminum.
The one problem is preventing aluminum oxide from forming.

The funny thing was, the very first time I made it, it was an accident. I was removing some aluminum foil from a tin I had made charcoal in and it caught on fire as I put it on a spot with a few hot burning coals. I quickly blew it out.
Sanding it down a little, I decided to mix (from what I can remember) something like sodium nitrate and sulphur with a bit of it.
It burned very quickly for sanded aluminum!

the Mg makes a great glitter effect and sometimes even Crackles a bit too.
Thanks

hi so should i stick a bit of ali foil in with wood when makeing charcoal and you get carbonised(ish) ail?No, I actually directly burned lampblack into soft aluminum in an inert atmosphere.

I guess if it's of no loss to you, you could try.
That's how I see it anyway.
