Crystals crystals crystal

Like crystals? Here’s a bunch of them. We made these crystals for our video on the chemistry of crystals and we thought you might like to see them on their own. We grew crystals from potassium aluminium sulfate (KAl(SO4)2, (KAl(SO4)2/potassium chromium sulfate mix, and sucrose (sugar). The methods used were evaporation, slow cooling and diffusion of ethanol in water. See the video for more details.

the close-ups of the crystals are so crisp🤩

And crruuunchy!
Stunning! I have seen some home grown single crystals., Not only a small seed is needed, but putting it in a very small and narrow hole within the crystalliser is crucial. By introducing a vortex into the solution you would end up with the best looking crystals! It's amazing that they grow following their lattice structure, allowing us to see in human dimensions the atomic bonding behaviour. Crystals were a crucial step in hinting us about atoms in the 1700's when people would break them and get blown away by the fact they would always get cut/broken at the same angle! Best regards, love your videos :)
So cool!! Beautiful crystals

Thank you!
I'd love to see more content on growing crystals. Would it be possible to grow quartz crystals at home?

I'm afraid not. Silica (quartz) is extremely insoluble, which is why it makes up most kinds of sand. (The Sahara is basically a landscape of tiny quartz crystals). If you have the patience, you can grow the sulphate crystals that we grew, but you'll need to varnish them afterwards or they'll dry out and crack.
