Is solid CO2 considered a hazardous substance in the

it in just about any medium-sized city in the US, usually sold by
"ice companies". Can one buy acetone in the UK, or is that also on
the proscribed list?
Your "friendly neighbourhood hardware store" won't sell it to you, and
neither will the chemists.... but that's what eBay is for :)
You can get everything you need to kickstart a cupric chloride etch tank
from ebay -- that's basically concrete cleaner
(hydrochloric acid),
high-strength hyrdogen peroxide, and a lump or two of scrap
copper.
Dry ice... that's a little harder.
