Hi all,
As a youngster I made a crystal garden, using chemicals which I could easily obtain at the local chemists (Copper Sulphate, Cobalt Chloride etc). These were dropped into a solution of waterglass.
I've now suggested to my eldest son that we make one of these - and have realised how hard these things are to come by these days! Can anybody suggest a supplier of these various chemicals, and the waterglass itself
- Unichem pharmacies don't tend to stock the same stuff that my local did 30 years ago!
Thanks
Gary
