Been trying to find some nitric acid locally to make into a rust blue solution I need to restore old firearms.

I found a lab supply company in Brisbane who will supply it to me (after creating an account naturally), but then the sticker shock.

500ml of sulphuric acid, which I also need, is $24. Not so bad.

500ml of fuming Nitric acid... $483!!!

500mls!!!!

Ouch.

Anyone know somewhere in Brisbane I can get some nitirc acid (reagent grade or better) CHEAPER THAN THAT?
