L/F Bluing Salts

[gerard]

Does anyone know where to buy Caustic Bluing Salts here in Canada?
I'm not looking for any large amounts just enough to do some pistol parts.
If theres anyone that can help it would be grearty apreciated. Or if you know a link to the manufacture you could send it to my email address achilds@eastlink.ca
Thanks Gerard

Sodium hydroxide and potassium nitrate at your local chemical supplier. You will most likely have to buy it by the bag 20kg I think.
