this is perfect for extracting gold really good quality

This is good stuff - for stump killer...and it makes a good smoke screen. By itself, it is not flammable when mixed with some sugar and it will burn very hot and make lots of smoke which helps keep the mosquitos away..

Helped kickstart my compost! Very helpful for sandy coastal soil

Not powdered. Very tiny BB’s. Will require purification for some uses, crystalizes nicely with only some minor oily coating on top of the water afterwards. Works great right out of the bag to get rid of stumps.

Great product

Exactly what I needed. Product performed as expected.

After a year, there's been no significant breakdown of the stumps. I cut out a cross-section with my chainsaw, and the holes that were filled with this product haven't spread sideways into the wood at all. But they're locust stumps, and locust wood is harder than oak, and famous for its resistance to rot. So maybe on a softer tree (pine, maple, poplar, oak) this might have worked better. What I really want to write about is my screwup. I wasn't as careful as I needed to be in handling this, and apparently got some on me, which I apparently ingested. Google says, "Ingesting potassium nitrate can cause significant gastrointestinal irritation. Common digestive issues include nausea, vomiting, abdominal cramps, and diarrhea." Regretfully, I can attest to the truthfulness of this statement. So wear rubber gloves, and wash carefully after using this product, and you should be okay.
