Potassium Nitrate 1 lb

It's KNO2. There appears to be some contamination in one of the bags I got, but VERY minimal. A few dozen grains of some sort of black and brown granules were mixed in, and I found 2 tiny pieces of what looked like cardboard. The other bag looks perfectly fine, though (haven't opened it yet). For my purposes, and most people's purposes, it's a non issue.

Works great

It was good quality. Oldest of 9 i always do a rocket build with each sibling to get them interested in space , as its gotten more of a dnagerlus world harder to do so, but it was a fun weekend it worked as advertised and he loved the rocket!

This powder had quite a few black specks of something in it. At first I thought they were dead bugs. I’m not entirely sure what they were but I had to sift them out before using in my science project. If you’re concerned about purity at least in my experience there was excessive debris in the bag. It appears to have worked fine in the experiment once sifted.

I used this product that goes in a recipe to make fertilizer for my plants. Mostly indoor plants. With my other ingredients it make plants greener and healthier looking. I had used saltpeter but could not find it anymore. It was potassium nitrate which I looked up on Amazon and found what I needed.

Works well, and came as described, would buy again no doubt.

Used it fir for aches and pain.

I used the chemical for fertilizer and made my own fertilizer compound and made the garden really grow. We used it for a science project. Easy to manipulate and measure and weigh. Worked perfectly in all instances. Tommy Arnn
