Amazingly fast crystal growth

Here’s a sneak peak of the demonstration that we will be using to start off the workshop. It gives a brilliant insight into how crystals grow in an ordered fashion. What we see here is mirabilite (Na2SO4.10H2O) crystallising amazingly fast due to the amount of salt that had been dissolved into the solution beforehand. The reaction is quite stable, and only begins when a seed crystal is added to the solution which acts as a site for the crystal to begin growing on.

I can promise that the video hasn’t been sped up!
