How to get KNO3

[Qaher]

yes I got it fom soil!
I brought the following:
1- KNO3 rich soil (you can better use goats .... but...)
2- Charcoal filter (home made)
3- Normal sieve (the one used for flour)
4- large cooking pan
5- Ethanol 96%

here's how it works,I filled the sieve with the soil and , and put it over the cooking pan and the filter was placed between the pan and the sieve.
I Pour slowly (with that thing which is used to water home plants) boiling water through the soil and the filter (I used 1 liter of water for each kg of soil) the water dissolved KNO3 while passing through the soil.
I boiled the filtrate gathered in the pan to half its original size, and poured same amount of alcohol and let it to stand.
nice white crystals of KNO3 were formed :)
the sad part is I used 20 kg of soil to get 1 kg of KNO3!!

excuse my english this is my first post

You should know that your first post should not be a new topic! It's in the rules. But at least it's a contribution rather than a question. :) Thanks.

Pretty much useless information and your first topic was a thread :mad:

So now you'll get banned.
