We bought this product to do a crystal project and waited eagerly for it, but the FedEx tracking kept saying it was late, and then FedEx ended up back-dating the tracking by a week to say it had been delivered (when it had clearly been lost). After jumping through several hoops to file a claim with FedEx, they called to tell me I had to get refunded from the seller (RotoMetals) and then they'd refund them. "More hoops," I thought, but Rotometals refunded my claim instantly. I re-ordered the product, it arrived in a single day, and we've been having great fun with it ever since -- highly recommend both product and seller.

Good quality, but recommend purchasing one at a time. If shipped in bundle it can get messy and you may lose some of the material they do, add more than is advertised. I guess to make up for loss or waste. But if you order in big bundles, you might run into significant lost each order comes in individual plastic baggies like zip bags, they bundle up in 2, but the surfaces are too sharp and hard. They will poke holes in the bag and if shipped in a box that's one, you will experience some loss of material. sometime you win sometime you lose, I recommend ordering it in individual orders. And be careful, they will bundle this up even though you order it days apart, so I will order it and place another order every time one's been shipped to avoid having them put into big boxes when they're in envelopes, paper envelopes their heavy duty and it actually will stand the shipping when it's shipped in boxes. That's where The loss occurs. I do recommend this product. Just be aware. I wouldn't push my luck.

Amazing. This bismuth was so gd bismuthy that the pepto bismol got jealous and up and left my house. It was so pure that, upon opening it grew an orifice to shoot rainbows out of. Although amazed, I was subsequently covered in rainbows for the rest of the day. Jokes aside this bismuth arrived as advertised. No complaints. Bought it to grow crystals with the kids and worked just fine. Pro tip: buy at least ten pounds to grow bigger and better crystals

Bought twice, because one wasn’t enough to make nice sized crystals as other reviews have mentioned so definitely buy more. I had no issues with the beautiful colors bismuth crystals come out in until the second batch was added which made all the bismuth crystals come out silver. The crystals did form but I wanted them to be in the cool colors so I’m confused as to why mine didn’t after the second batch. I used all the same things as the first time so nothing changed on my end. This bismuth is great for the prize and creates beautiful colors I would just purchase a bigger amount at the same time so it’s from the same batch unless I just got an odd Batch which is why my crystals came out colorless.

This metal is pretty good for my casting experiment because I can melt it at home with an old pot I no longer use. It is also easy to break it into pieces and melt it again because it is very soft. I would like to try making some crystal later as well. I bought 6.6 pound for the 9” diameter ring I casted. If you want to make something big, 2.2 pound is definitely not enough.

Because the material gets rather warm, be sure to treat it like you would, say, a pot of boiling ramen noodles or such. Eye Glasses--any--are well-advised for the extraction phase at the end. Wear shoes, too, as you ought to with boiling water, etc.. Cooling appears to produce better results when gradual. We insulated our old, small pot with a loose wrap of foil and a lid. The surface crust must not get too thick or extraction of the crystals within is not possible. If it does get too thick, just start over. So far, results are excellent. See youtube for more info: Bismuth.
