Make Bismuth Crystals

Bismuth crystals. They are majestic and beautiful looking structures, and since bismuth melts at 520°F, it can even be made at home — if you have stainless steel pot you don’t mind sacrificing for science.

All you need for this is a stove, a stainless steel pot, and a stainless steel spatula. Take a look at the video below to see how we did it.

Lab notes:

  • Stainless steel is easy to clean up as the bismuth scrapes off easily.
    • Bismuth is non-toxic, so you can reuse the cleaned implements without fear.
  • Cooling the bismuth slowly will create bigger crystals (and give you more time to pull them out).
  • Bismuth can be melted a few times over if you want more trials.
  • Patience is key!
