Bismuth Mineral is , brittle, steel-gray metal with a pinkish tinge.
The most common bismuth minerals are bismuthinite and bismite, but most bismuth is recovered as a by-product from lead processing.
Bismuth is a moderately priced metal, costing more than copper, lead, and zinc, cost much less than gold or silver does.
Bismuth is used in a number of very different applications. Almost none of the uses is for pure metallic bismuth. The majority is consumed in bismuth alloys, and in pharmaceuticals and chemicals. The remainder is used in ceramics, paints, catalysts, and a variety of minor applications.
Industry uses bismuth in a variety of other applications. Bismuth is a catalyst in the production of acrylic fibers. Bismuth replaces lead in some ceramic glazes and paints, because bismuth is non-toxic.
How to make Bismuth Crystal.
Bismuth is one of the easiest and prettiest metal crystals that you can grow yourself. The crystals have a complex and fascinating geometric hopper form and are rainbow-colored from the oxide layer that quickly forms on them. Follow these step-by-step instructions to grow your own bismuth crystals.

Bismuth has a low melting point (271°C or 520°F), so it is easy to melt over high cooking heating. You are going to grow the crystals by melting the bismuth in a metal “dish” (which will have a higher melting point than the bismuth), separate the pure bismuth from its impurities, allow the bismuth to crystallize, and pour away the remaining liquid bismuth from the crystals before it freezes around the crystals. None of this is difficult, but it takes some practice to get the cooling time just right. Don’t worry—if your bismuth freezes you can remelt it and try again.
Step By Step Guide to making Bismuth Crystals.
Place the bismuth in one of your metal dishes and heat it over high heat until it melts. It’s a good idea to wear gloves that protects you from hot surfaces, since you are producing a molten metal, which is not going to do you any favors if it splashes onto your skin. You’ll see a skin on the surface of the bismuth, which is normal.
Preheat the other metal container. Carefully pour the melted bismuth into the heated clean container. You want to pour the clean bismuth out from under the gray skin, which contains impurities which would negatively affect your crystals. Watch the video (bottom of Post) for other ideas.
Set the clean bismuth in its new container on a heat-insulated surface (e.g., set the container back on the burner, but turn the power off). The cooling rate of the bismuth affects the size and structure of the resulting crystals, so you can play with this factor. Generally, slower cooling produces larger crystals. You do not want to cool the bismuth until it is solid!
When the bismuth has started to solidify, you want to pour the remaining liquid bismuth away from the solid crystals. This happens after about 30 seconds of cooling. You can tell it is about the right time to pour the liquid away from your crystals when the bismuth is set, but has just a little jiggle to it
Once the crystals have cooled, you can snap them out of the metal container. If you are not satisfied with the appearance of your crystals, remelt and cool the metal until it is just right.

I hope you enjoy this small bit of information on the mineral Bismuth. I have ordered my Bismuth, I am going to make some bismuth Crystals too.
Leave me a comment If you make crystal. leave some pictures.
Have a great day.
