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.

Good quality and no clumps in the bag. Highly recommend if you need some Potassium Nitrate for any reason. Good for stump removal and at an economical price.

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.

Appears pure and finely milled.A nice chemical.

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.

I use this product in a similar manner to Spectracide stump remover. If applied as suggested, the results are quick and dramatic. It probably took less than two weeks, post application, until the stump cracked into many fine splits between the bore holes. YMMV, but my experience has been positive thus far.

Good quality KNO3 with a great price and fast shipping.....

Very pure product. Great for any types of experiments.
