Making Calcium Metal

Having made some serious progress on our series of molten salt electrolysis experiments (successfully isolating aluminium, sodium, and lithium in other videos), we make an attempt at a particularly tricky metal to extract - calcium.

You can find the other videos in this series here:

In the video, I also refer to the following video by Cody'sLab, in which he extracts calcium metal from bones:
