'Titanic' immediately came to mind Roger - steamship and iceberg all-in-one. Mesmerizingly intricate shapes and light.

Superb.

Thanks for your thoughts, All.
Actually, I was surprised to see the crystals there this morning.
The solution was saturated &, I think, evaporation (of some of the water) overnight change the state of the solution from concentrated to saturated.
Leaving the solution no choice but to form crystals at the bottom of the pot.
Thanks for looking,
Roger.

The more I look, the more there is to see!

Fascinating. What size is the clump? I'm guessing at 2 or 3 millimeters?

Wonderful! And nostalgic. It's the sort of thing that first got me interested in chemistry (many, many years ago...).

Thermal and density gradients, convection and solubility varying with temperature probably had a role in it. One of my children once grew a 'huge' (2+ inch long) crystal of copper sulphate by suspending a tiny crystal in a jar of solution and leaving it on a window ledge. After a while, the crystal started to shrink and small crystals grow on the bottom of the jar, just like yours. It could all be explained by convection currents, differential solubility, density gradients etc. More importantly, the main crystal was quickly removed and varnished while it was still big enough to be impressive. I think she still has it.The solution was saturated &, I think, evaporation (of some of the water) overnight change the state of the solution from concentrated to saturated.

A fascinating subject and beautifully presented. Well done you.
