I quite often make subassemblies and parts by soldering brass. I have several chemicals that very effectively blacken the brass: the best is Birchwood Casey but Blacken-It works too. But neither of these works very effectively on (standard) lead-based solder. Any suggestions for another chemical or am I stuck painting them? TIA Norm

Brownell's used to carry a solder-black for sweated joints, don't know if they still do. Be aware that any of these compounds doesn't leave a very durable finish. Flat black lacquer works well for me for camera stuff.

The last time I picked up a bottle of gun blueing, it indicated that it was for "steel" only. That's why I have the B-C Brass Black.

I didn't see any in the catalogs I have. Just ordinary "steel" and "brass" specific stuff. Norm
I'll check out the local craft stores which do carry some stained glass supplies.
Thanks Norm
