Home nitre salts bluing

[upinsmoke69]

Here are places to get Kno3. Ammonium nitrate (salts). Try instant coldpacks but check ingredients before buying. Stump remover could be 90%. I have seen bags of it in grocery stores for curing food. Their is a method to get it from dirt also.

Kno3 is potassium nitrate not ammonium nitrate. Amazon is a good place to get it.
