## Overview

ESKS® 5lb Potassium Nitrate is a high-purity (99%+) reagent-grade powder, water soluble and packaged in a resealable zipper bag to maintain freshness. Widely used in pyrotechnics, black powder production, hydroponics, and stump removal, this versatile oxidizer is trusted by professionals for consistent performance and secure shipping.

## Description

5lb Potassium Nitrate Milled The most extensively employed oxidizer in pyrotechnics. It used for a wide variety of applications, the most important of which is in the manufacture of black powder. Potassium nitrate is a white powder or long needle-like crystals before being milled to a fine powder. *Packaging may vary from pictured, but guaranteed to be high barrier to ensure freshness and longevity.

Review: Quality KNO3 - They started double bagging it due to complaints of leaks. I've ordered twice now and haven't lost a single granule. Much better shipping process. Quality oxidizer. Popular for sugar rockets. Granules large like sugar. Needs to be ground to a confectionery sugar consistency for r-candy mixes. I transfer it into a 4 quart container using a metal 1" funnel. You can also find the funnel on desertcart. SDS stickers really help in labeling all of your chemicals. This KNO3 doesn't have to be water boiled as it's already 99% pure but it is possible to refine it to a higher purity if you want a little extra impulse. This is my go to supplier for sugar and BP rocket KNO3.
Review: Works great - Works great for nitrating paper for blackpowder.
