my chemistry teacher was growing some kind of copper complex crystal in the lab. it was like his baby. it was there the entire 7 or 8 years I was there and big even at the start. it must have been almost a foot across
Very well done...I particularly appreciated the demonstration of the exotherm that occurs during crystallization....a nice display of the heat energy locked up in the supersaturated solution. I've done this hundreds of times (C0kement0s (see my elephant toothpaste), on contraptionists (my sons) account)
Are those hotpacks reusable? I wasn't sure I hadn't heard that they were but my partner says they are. Today he took a used one. I.e. totally crystallised and heated it up in a pan of water. Oddly enough he hasn't said anything about it since lol.
The glass don't break?

I didn't use a seed crystal and it worked anyway.

@1000jamesk sometimes works without a seed crystal but usually if you dont use one,the mixture gets contaminated with however you start it

Where to get this chemical ?
Sodium acetate
I wanna make it too :D
Heatpacks are great

Woops, strong base containing sodium I meant to type

just mix vinegar ( acetic acid) with sodium bicarbonate ( baking soda) and then heat the solution to saturated point.

Thank you. Yes I realise that they are now. I just thought the metallic disc was only good for use. Its good to learn.
