Kilogram Bismuth Metal 99.99% Pure

Melted easily with a blowtorch. Makes good crystals if you treat it just right. Warning: Do NOT melt it in pyrex on a stove. I did this at first and forgot how quickly the bismuth would expand as it starts cooling and solidifying. Molten bismuth got all over my stove. Fortunately it doesn't actually stick to the stove, so I was able to peel and chip it off. My recommendation is a small metal bowl sitting on top of some rock wool as insulation and using a blowtorch (the kind plumbers use).

Its exactly what it says it is. its metal. the manufacturers package that it came in was broken when it arrived. and it was exactly a kilogram.

Cool stuff! Fun to see the different colors and designs it makes. Packaging was really good, in a good heavy plastic so there were no punctures or tears in it. Actually weighed in at 2.4 pounds, so that was nice too. Different cooling rates will change the color and designs, fun to experiment with. And you can re-melt it over and over as many times as you like.

Came as advertised. It was broken up a bit, but it is fairly brittle, and to be expected. We plan on melting it to grow crystals (watch on YouTube) so it didn't really matter.

The bag it was packaged in was pierced and there were a lot of little pieces/fragments that got everywhere, but it wasn’t a big deal. It mostly came in 3 pieces, one big and two much smaller ones, and weighed 1019 grams without the bag. Melted fine at 520-530F with a decent amount of slag but nothing more than expected.

Good stuff. High purity. Low melting point makes bismuth a fun metal to experiment with at home with a few household items. No need for any special equipment if you have a few old pans around (and a camping stove or similar heating element for outdoor use). Growing some bismuth crystals is an easy activity that doesnt take much preperation or time. (Check out some of the youtube videos to get an idea of what to do)

If you love to collect rocks and metals like I do then you have to get some of this stuff! Not only can you melt this and make cool crystals but it just looks and feels cool when you hold it in it's raw refined form. This came from a large slab of melted refined bismuth so there are mold marks on it and it seems they used heavy industrial shears to snap off manageable pieces for sales. Very clean looking metal and seems very pure although I am in no means someone to verify it's purity. I'm keeping it in a sealed tuperware container on my display shelf for now. Very heavy dense and neat looking metal! Weight was spot on with a little over!

What can you say about 4 chunks of bismuth metal? Ordering was easy, delivery was quick, the material was as promised. The intended use is as a science demo to show properties of metals by growing bismuth crystals. This produce is perfect. Based on my experience with this vendor, I expect I will purchase more, as 4 pounds of this very dense metal may not be sufficient for the project.
