In this demonstration experiment, we show how we can make a beautiful single crystal of bismuth. To do this, we use a special metal rod and immerse it in a molten bismuth bath at about 280°C. When the bath cools, the liquid bismuth solidifies in the colder areas, but also on the metal rod, which is colder due to heat conduction. The trick now is to wait for the right moment to pull out as large a crystal as possible from the liquid melt. At the end of the demonstration experiment, you will learn which crystal production methods we use and why these methods are important for us.
