Rainbow Metal Sea Shell! Making Crystals and Metal Casting With Bismuth!

Published 2023-05-27
In this one, we take some of my favorite material on the planet and play around: Bismuth! We first make some amazing hopper crystals, before moving on to some lost wax casting of sea shells. Due to the very low melting point of bismuth, it is a heavy metal that can be smelted on a stove top! I hope you all enjoy and I'll have another one out soon!

Want to make your own Bismuth creations? Here is a link to where I get mine from!:

    I love bismuth! It is so beautiful and it's crystal structure is so unique and beautiful! It is a uniquely different metal and as you said, one that everybody should play with at some time! Lol! I whole heartedly agree! Thanks Theo, and I hope you are feeling better now. Food poisoning is not fun and will leave you drained and devoid of energy! So I hope you are feeling well soon!

    Thank you so much for persevering in spite of not feeling 100%! I hope you’re back to full health soon. Take care!
  • this is so freakin cool in several categories ! extremely beautiful !
  • I absolutely love bismuth. I bought a couple crystals from you a couple of years ago. This would be so fun to work with. I so love the work you do.
  • If I knew more about chemistry I would understand this more. But this was just so fun to watch. Interesting and beautiful
  • Ooo, they lok like alien cities. And the shells are absolutely georgious👍💕🇫🇮
  • Bismuth is so cool on so many levels & really enjoyed all your trials and searches for good creations. I've often wanted to take a compressor/vacuum used for resin treatment (and also air conditioning lines) with a heat source rigged up.. Just curious as to what the Crystals would look like with the absence of oxygen. The down side would be you couldn't touch or mess with it inside. Great episode Theo

    dude this wa exceptionally insightful.Although pouring the bismuth into a fresh plaster mold wasnt a great idea due to the moisture in the mold, i think it is extremely helpful for new metal casters to see what happens, the bubbly popy stuff is way more dangerous when its hotter metal pours like bronze, this helps avoid accidents. thanks man , keep making cool stuff!

    Hey thanks for the Tips ! You're a legend . I tried Casting with Bismuth for the first time yesterday in an enclosed heated CNC engraved Graphite mould I have previously used for Brass. I had the Idea slow cooling would produce Rainbow annealing but perhaps it wasn't slow enough. I'll certainly try just torch heating it . Yes as you realised Its good to Bake your moulds to reduce trapped water when using plaster or clay moulds ..🙂.the spitting can be bad !
