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.

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)

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.

Although the weight (1 kilogram ) was accurate, the metal had no detectable diamagnetic properties. When ferrous or Neodymium magnets were suspended right next to and contacting the metal there was no movement, attraction, or repulsion between the magnets and the metal. It also lacked the "pinkish" tinge to the bright silvery color described by most and seen in photos. Was probably just a contaminated segment of the vein being mined or a contamination introduced during the ingot melt and pouring. Either way, I suggest you verify with the seller the purity of the Bizmuth before you buy. or some

The metal itself seems fine so far, but my issue is with the comically bad packaging. The "BPA-free packaging" that is supposed to prevent oxidation? Not so much. Their "packaging" is a lightweight resealable plastic bag that is at least 45% clear plastic tape. Unsurprisingly, it completely split open and disgorged its contents into the Amazon bag. Which also ended up with more holes in it than Swiss cheese. I have no idea how much of the actual metal was lost, but I'm guessing any piece smaller than a mm (that isn't stuck to the tape's adhesive) is entirely gone. I would skip this listing and find another-- one who actually knows how to package their goods.
