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

Would recommend

Burns very steady with extreme brightness. Due to its thickness it is difficult to light using a typical lighter, but piece of cake with a propane blow torch. The ribbon hold its circular shape and resist shaping. It can become brittle and break when bent into tight curves. Anyway it is great fun for the money!

Exactly what I needed. However it takes a bit longer to light probably because of thickness. I was able to fix this issue by putting the piece in vinegar before trying to burn it (it will make it thinner). Which is fun because that creates hydrogen gas so you can do it in a closed container and then light off the gas when you're done.

The ribbon is, indeed, made out of magnesium. It is not 99.95% pure, that's for sure, but it's high enough purity to light off okay. It was already disappointingly oxidized upon arrival, but still lights. Would not recommend for any chemical experiments, but if you've bought it like me because you like lighting off magnesium strips and watching the pretty light it functions.

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 burns hot when you need it to and is a great value

I’ve used magnesium ribbon to like thermite for welding for 20 years or more. This ribbon is hard to get lit and stay lit once its going. To dangerous to use for igniting thermite since it’s necessary to stay very close to make sure it stays going. It give of a light blue/pink color when it is burning at times not the normal bright white. I’d say it’s slightly contaminated with another metal, Aluminum, cobalt or copper(1) oxide all burn blue, several metal burn pink also. I was surprised since the store was highly rated. Maybe just bad luck IDK I will try them again,

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.
