Magnesium Ribbon High Purity Lab Chemicals 1 Rolls 99.95% 25 g approx 70 ft (Original Version)

As described. Value. Works for my experiments.

Would recommend

Definitely High Quality Magnesium Ribbon. A little thicker than most. So if you are having problems igniting it, keep in mind that you are attempting to ignite METAL. So it's not just going to flare up with a flick of your Bic. You can probably get it lit with your lighter or matches ( note the plural "Matches"), but it's going to take a while. If you are doing demonstrations or are outside with any wind, I highly suggest using a propane torch. Caught right on in under 3 seconds with my propane torch. No torch? Buy one they're handy. My second suggestion for an igniter is to use firework sparklers, preferably gold colored ( the hottest burning). And be careful! Magnesium burns at about 4000 ( Four Thousand) degrees Fahrenheit, 2200 Celsius. Do not extinguish with water or CO2, it does even worse things. Smothering with sand is the standard procedure and that's just to keep the fire from spreading.

It's fine but you "must" sand off the oxidation or it will not continue to burn but is as expected once you sand it off.

Picked this up for an element collection I've started. The magnesium is actually magnesium (shocker) and does burn with a bright flame. A quick tip to light it more easily is to cut it with (junk) scissors so that there is a narrow point at one end. This makes for a smaller thermal mass to heat up and you can reliably light a strip with a Bic lighter.Something folks should be aware of is that the "roll" is not a continuous roll but rather a collection of strips around a foot long. I doubt this will be a problem for most folks doing amateur chemistry demos (like burning strips), but something to be aware of if you are expecting longer lengths.

I use this every Halloween. Students love when I burn the magnesium and it glows white brightly. Just be sure you have a metal tray underneath, tongs to hold the piece of magnesium, and a fire extinguisher nearby. Cut it into smaller strips for safer management. One roll lasts me a long long time since I don’t need much for each demo.

I ordered this 3 weeks ago and it's been in transit for two weeks. We have magnesium on this planet last time I checked. As for the folks not happy with extinguished magnesium ribbon that is touching stone or brick or metal, you have to understand the fact that magnesium has very little molecular density of mass. (less than an oz. of weight stretches over 70ft.) Any heat sink material such as stone, steel or concrete will suck the heat energy necessary for combustion right out of this stuff. You can only use it to ignite other light weight substances that require a quick introduction to high temperature. Underwater welding rods are thick and ribbon is not. If you want magnesium that burns furiously, you want the powdered form. I will re-visit my star rating after delivery and experimentation.

also great for science class
