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
