Bismuth is a heavy metal and in the periodic table of chemical elements is located next to the Lead. Bismuth is a shiny and very brittle metal. I bought bismuth in these sticks which are very easy to break if you slightly hit them with a hammer.
The breaking point shows that bismuth rod has a very clear crystal structure. Now I will melt it to show you one interesting property of bismuth.Bismuth’s melting point is 271 degrees Celsius, so it can even be melted on a hot plate. And unlike lead, bismuth is not toxic.
Bismuth’s surprising property is that it starts to form beautiful crystals during solidification.
The size and shape of the crystals will be dependent on the solidification rate, as well as the presence of impurities.
