A word to the wise
If you try to buy the ingredients stateside, you will get the NSA knocking on your door. They can be used to make home explosives...
BTW, guys. Can you use the vinegar to clean pitted or stained blades? If so, how would you go about it ? I have had mixed reactions to this possibility in the past, I'd like to hear yours. Likewise with the RS etchant.

Polish and immerse in BOILING water to heat the metal--this is important as the heat is need to make the process work. DON'T USE A FLAME AS IT WILL MELT THE SOLDER AND THE BARREL JOINTS WILL FALL APART. Apply solution with a CLEAN cloth EVENLY. Wash in fresh water and dry. Polish in between applications with fine steel wool. Repeat the process. Once you get the colour you want immerse again in BOILING water to cure and stop the action. (Browning and blueing are both an artificial "rusting" process)
You can buy browning paste but I have not found that it is suitable except for VERY MINOR touchup.
The mixture I used is :
64 GRAINS Mercuric Chloride
32 GRAINS Sodium Nitrate
64 GRAINS Potassium Chlorate
64 GRAINS Spirits of Nitre (4%)
32 GRAINS Potassium Nitrate
Distilled water to 1/2 Pint
You will have to find a manufacturing chemist to make up your solution, or someone who has access to the chemicals. They are a bit thin on the ground these days as most chemists just sell pills!!
Good luck and let us know how you get on.
