Enjoy home experiments? Or just captivated by crystals? Take a look at NightHawkInLight's YouTube video, showing you how to use cheap bismuth ingots - bought easily online - to make stunning bismuth crystals. Bismuth has a very low melting point, 271.5 °C (520.7 °F), which means it’s possible to melt and mould at home using only a kitchen stove, pan and safety equipment.
Once heated to the correct temperature and the ingots have melted completely, remove the metal from the stove and allow it to cool - this is where the magic happens as during cooling, the oxides and contaminants within the bismuth rise to the top where they can be scraped off, leaving the bismuth crystals to form underneath.
Safety equipment, is of course, recommended for all stages of making your own crystals.
