Source for a small quantity of Nitre Bluing salts?

[Chuck Gedraitis Knives]

Anyone have a source where I can buy a small amount of nitre bluing salts? Brownell's sells it in 20lb pails and I don't need that much. Any help would be appreciated.
Thanks,
Chuck

Hi Chuck!

I doubt your going to find it in less than the #20 bucket......but if it helps any, I use the stuff, and it took the whole #20 bucket for my tank (18"LX6"DX4"W), once it started melting, I was trying to figure out where it was going.....thought the tank was leaking, but it just melts down to nothing.
