Ever wanted to make your own bismuth crystals? Well you can by following these steps.
: As much fun and pretty as these crystals may be please be aware that this is metal. Melting metals will give off fumes; try to avoid breathing in those fumes for health reasons. For complete details on bismuth and its' properties please read the Material Safety Data Sheet (MSDS) found here: http://www.sciencelab.com/msds.php?msdsId=9927101
Metal Bismuth (99.999% pure bismuth is preferred. The cheapest place to acquire some is at Roto's Metals; they sell it by the pound: http://www.rotometals.com/Bismuth-s/4.htm)
2-3 Stainless Steel cups (stainless steel is preferred but aluminum cup will work too. They can be found at any store that sells kitchen accessories. For this example a muffin tin was cut up and used.)
Stove top or Hotplate (propane torch optional) (The hotplate can be found at almost any chemical store online.)
