Homebrew PCBs

Hi,
In your photos of the process you say that Cupric Chloride is available
at hardware stores.
What do you ask for?
Thanks for the info,
Dan

GOOD question!  I have ONLY seen it in H.S. chemistry class!  Someone TELL 
us!

Actually he didn't say that. He said Muriatic Acid is available in
hardware stores. It is used for cleaning brickwork, and I think in
swimming pools and maybe hot tubs for balancing PH.

Don't forget to check the links on the Homebrew PCBs home page.
There are many sources of such chemicals there.

And if you find something that isn't there, please add it in the
appropriate area.

Getting confused in here. Is it Cupric Chloride or Copper Chloride. I  
am not a chemist but the guy at the hardware store laughted a lot when 
I said cupric instead of copper chloride. 
This is waht I found:
