IF there is, you will very likely get lot's of experience with thermite and it's hotter sibling thermate. I know I and many other Marines did in Fallujah, Iraq during '04-'05 - The most fun city to be in during that time as a Marine. We used thermate often to render useless the countless weapons we obtained off of the enemy. Even if you don't get any combat experience, you'll get some practice with it but that's not as fun. Don't stare directly at the thermate, it's like staring into the sun. **Q: Could you tell me if this is the same as red ochre?** A: Yes, most people would refer to red iron oxide as red ochre **Q: Will this work on hydrangeas to turn blue?** A: Red iron oxide will not work. To turn hydrangeas blue you will need a soil acidifier (some people use iron sulfate, sulfur, aluminum sulfate, or others). The pH of your soil will have to be lower than 5.5 for them to turn blue. **Q: Can this be used for oilskin ?** A: I used it to dye muslin and silk. It did not produce as intense a color as I had hoped. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great, non-toxic, non-fading coloring *by K***R on 22 July 2025* ### ⭐⭐⭐⭐⭐ Useful material *by J***C on 2 May 2018* ### ⭐⭐⭐ More red than orange *by B***E on 23 May 2019* ## Frequently Bought Together - Red Iron Oxide - Fe2O3 - Natural - 5 Pounds - 2 Pack Magnesium Ribbon High Purity Lab Chemicals 2 Rolls 99.95% 25 g Approx 70 ft Awesome Industries - 6 LBS #120 Aluminum Oxide - Fine Sand Blasting Abrasive Media for Blasting Cabinet or Blasting Guns (6 pounds-120 Grit) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/51649555-red-iron-oxide-fe2o3-natural-5-pounds](https://www.desertcart.co.uk/products/51649555-red-iron-oxide-fe2o3-natural-5-pounds) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-30*
