Subject: CuCl

From: Naveed Alam <naveedguy2@...>
Date: 2005-03-02

I bought a copper board. The shop-keeper also gave
CuCl but that is in the solid form. Can anyone tell me
about the proportions of water and this solid used to
prepare solution for etching. Can I also use some
other chemical to improve the etching process or make
it faster. It's black in colour. Is it OK?
