Potassium Nitrate Technical Grade KNO3 4LBs 4 LBs (Milled)

Perfect for making antique muzzle loading propellant. I've used it making a couple batches and it works very well for the price.

Very fine powder and is packaged well and sent out quickly it’s well worth it’s cost!

Good quality but I doubt it’s 99.99% pure. Haven’t found one that actually is to be fair. Great for making antique muzzleloader propellant.

You get one 2 lb Bag NOT 4 lbs as advertised in the listing. It does mention 2 lbs way down the ad! Just so You know! Some is very Dry other bags in multiple orders is hard clumpy. Sieve it and Dry it it well before making Antique Ml propellant. Other than that it is good stuff as is for purity! Mill it Right you’ll own Swiss!

Delivery is fast. I got exactly what I wanted. Very happy.

This is pure potassium nitrate. Works great for the pyrotechnics that I use it for and for this price is also a steal. I diy with my kids making sugar rockets, gunpowder, and numerous other projects they get off of TKOR on YouTube. So we go through plenty of this very quickly. Will make this my primary supplier from now on.

Very high purity and lab grade. I would say 99 percent purity and is very useful for my project. Fast shipping. Would buy next time.

I purchased this product for one purpose and that was to make nitric acid. As it turned out the strength of the nitrogen was not even strong enough to make red fumes when mixed with sulfuric acid. (Very strong acid) very disappointing to say the least. However the product i recieved was in fact clean and neat as expected from a lab, though useless for the intended purpose.
