I want to make my own kno3 from gunpowder. I obtained gunpowder from a nearby shop. Can you tell how to extract kno3 from it?

Do you realize that KNO3 you can get in normal market shop with food.. ? At least here.. It's used to pickling meat..

I bought it not once. In Leroy Merlin also they sell it.


One way that comes to mind, although I have not tested it, is using water.

KNO3 is soluble in water, while carbon and sulfur, not.

I would try filter column (like below) and leave it alone for days or weeks and see what happens.

KNO3 is used as a fertiliser. You can buy it at a garden centre or in petshops as an aquarium fertiliser.
When I was a kid I used it to make smokebombs >:D
