Bismuth is non-toxic and has a number of very interesting properties. For best results I recommend using at least 4 or 5 pounds of bismuth for the surface crystallization method demonstrated in the video. The deeper the pool of bismuth is in the pan the better, because the crystals will have extra room to grow before they touch the bottom. The more you use the more impressive your results will be.
Some of you that are familiar with other forms of crystal formation may be thinking I gave bad advice when I state in the video that you can move the crystals as they grow. Usual crystal growth requires a very still solution with no movement, and a very slow cool down period. I did quite a lot of experimenting with this method and found that bismuth does not behave quite the same way. Once the crystals have begun forming it does not seem to matter if they are moved so long as they remain submerged. Further structured growth happens regardless of disturbance once there is a point to nucleate from.
You may also notice that I was not wearing gloves for a portion of the video, that was foolish of me. I was wearing eye protection the entire time. Leather gloves (not synthetic!) and lab goggles should always be worn in case of splashes or spills.
If you would like to skip the process of making your own crystals, you can buy them already made here (another affiliate link): [ Ссылка ]
