Alaska is where I started making my own rust bluing solution, because it cost so much to get items shipped to AK.

The Niedner formula” is basically Aqua Regia, a mixture of Hydrochloric and Nitric acids. Aqua Regia is used by the gold miners/mining industry as it will dissolve gold. Check with companies that supply the gold industry, there was a company in Anchorage that had all that stuff, when I was there,  Hydrochloric, and Nitric acid was easier to find in AK than the lower 48.


Thanks for the tip.  I'll look for some nitric acid next time I'm in Anchorage. Things aren't as simple as they used to be. This is a bit off-topic but when I was a kid the hobby shops had small bottles of various chemicals for sale.  I was able to concoct a few interesting compounds, some of which would even launch a simple rocket.  Probably a good thing we hid behind a tree during liftoff!
