Could you guys name some products that contain potassium nitrate, and that are available in normal food stores?
Nitrates are used to cure meat (a type of preservative,) even the "no nitrates added" organic shit uses celery juice as a natural source of nitrate.
If you're planning on getting any appreciable amount, grocery store products will not get you there. Your best bet is probably a garden or agricultural fertilizer that is mostly (>50% w/w) various nitrates, just pay attention to the other ingredients and understand purification. The Anarchist Cookbook says you can get meaningful amounts from water extraction of ordinary earth. Take that as you will keeping in mind the AC's general quality.
I wouldnt recomment potassim nitrate, unless you want to make tiny smokes or selfmade fireworks
if your into the real stuff you really should consider using ammonium nitrate or others. Its easyer to get (atleast in Europe) and safer to prozess.
Nope The Anarchist Cookbok isnt always a safe source for this kind of stuff.You really should macke backgrund-checks of the recepes before using. But i have to veryfy that fertilizer is a often good to extract nitrates and urea.
I heard they sell fucking fireworks in Toys-R-Us in France. Is it really that hard to find a pyro supplier in Europe?
Unless by "Europe" you mean Britain, in which case I totally understand.
