MADE IN USA. This is the best quality Potassium Iodide you will find. Excellent as a Lab Reagent or for any analytical purposes. Intended for lab or scientific use only. NOT intended for food, supplement, or drug use. There are no instructions with this material as Potassium Iodide has many different uses across multiple industries. Bottle will be about half full due to heavy nature of material. Picture may not reflect new GHS labeling. This item is NOT for resale! Review: The real deal... - I have used this product for some time and it works excellently. Great for everything from pesky dermatological conditions to reversing cancers, this stuff works. This is what you use to take gram level doses of iodine, just like iodine pioneer doctors Albert Szent-Georgi, the Nobel laureate that isolated Vitamin C, and D.C. Jarvis, who popularized iodine in the 1960s. Both took daily gram level doses of iodine, and both lived to be 94. 1/4 teaspoon of these crystals equals one gram of iodine. I put mine in coffee, cappuccino to be exact. Use this during the winter and you will not get a cold or flu. Harry Hoxsey, who ran alternative clinics and successfully treated thousands of cancer cases in the mid 20th century, used a formula containing 70 percent potassium iodide to treat his patients. This article is instructive in the use of potassium iodide. [...] These crystals are an essential part of any alternative healer's medicine chest. Review: Excellent quality but large crystal size - I'm a middle school science teacher and like to make Iodide solution as a reagent for elephant toothpaste. The chemicals are excellent quality but come in coarse crystalline size (1mm+ crystal size). If you need to dissolve small quantities of these Potassium Iodide crystals I would recommend getting a mortar and pestle to smash them smaller. You can also place the crystals in a freezer ziploc bag and smash them from the outside but do expect to get holes in the bag and powder everywhere. ## Features - Source - Made in the USA - Packaging - Packaging May Vary - Package weight of the Product: 1.59 Ounces - Package Dimensions: 2 inch L x 2 inch W x 3 inch H ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B008D8161I | | Best Sellers Rank | #16,406 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #9 in Inorganic Reagents | | Brand | ChemCenter | | Brand Name | ChemCenter | | Container Type | Bottle | | Customer Reviews | 4.5 out of 5 stars 506 Reviews | | Item Weight | 5 ounces | | Manufacturer | RND Center Inc. | | Model Number | 43237-2 | | Molecular Weight | 166 | | Molecular weight | 166 | | Package Information | Bottle | | Part Number | 43237-2 | | UPC | 691054867642 | | Unit Count | 3.5 Ounce | ## Product Details - **Brand:** ChemCenter - **Item Weight:** 5 ounces - **Molecular weight:** 166 - **Package Information:** Bottle - **Unit Count:** 3.5 Ounce ## Images ![Potassium Iodide, High Purity Crystals/Granules,100 Grams (3.5 oz.) - Image 1](https://m.media-amazon.com/images/I/61gL+Ww8EYL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: All instructions for elephant toothpaste use liquid solution. would i use the crystals the same way? or do i need to turn the crystals into a liquid?** A: Fill a 500 ml vial containing 15 grams potassium iodide with water. Cap and shake until all the potassium iodide is dissolved (This should now be a saturated solution of KI made with 15 grams of KI and water.) Set aside. **Q: I am looking for 'iodine crystals' to make lugol's. Which one of your products do I use?** A: You need "Potassium Iodide" and "Prilled Iodine Crystals" to make Lugol's. I don't see any Prilled Iodine on amazon right now (there is one listing but it is sold out). Search ebay for Prilled Iodine. **Q: I am looking for sodium iodide to make elephants toothpaste, will potassium iodide work the same?** A: I actually bought this a few months back for a science project myself involving elephant toothpaste. This does work, however when combined with 3% Hydrogen Peroxide, it is a terribly slow reaction. Combined with 35% Hydrogen Peroxide though was the best combination my partner and I saw. It expanded about 5x its size in under 2 seconds. **Q: What are its uses and at what volume?** A: I used it in a science class for an exothermic reaction,as well as time delaying reactions and accelerating reactions. 100g makes a largish reaction. ## Customer Reviews ### ⭐⭐⭐⭐⭐ The real deal... *by M***R on May 31, 2013* I have used this product for some time and it works excellently.
