  10. Rated 5 out of 5

    Robert Schirmer (verified owner) – June 19, 2021

    I’ve purchased P.P. from every retailer that offers it for sale online. This is by far the highest quality and its an extremely fine and free flowing “clump” free chemical, versus the typical chunky chemical in need of further processing that most other retailers are peddling. Fireworkscookbook doesn’t drag their feet in getting orders out the door. Don’t waste your time looking elsewhere, you’ll never find better product for any price and you’ll never find a more trustworthy place to purchase the majority of your firework related needs. Thanks again!

    Pretty good stuff high quality

  27. Rated 5 out of 5

    Emanuel Rivera (verified owner) – July 17, 2025

    I give it 10 stars because this chemical is finely ground. I’ve put others through a 100-mesh screen and they leave very small granules, but this one has very good quality. Even when you pass it through a 100-mesh screen, it goes through very well, like talc — very good.
