Homebrew PCBs

Last night I added 1 litre of HCl (30.5%) to 2 litres of distilled
water to make 12 litres of 10% etchant (to start off with) in my
plastic Coleman cooler tank. To this I added 1.8 kg of clean copper
wire I had washed in dish detergent and hot water.

Twelve hours later, the copper covered with the acid solution looks
unchanged. About half the wire, which is pieces about 12" long bent
into different shapes, (so the copper is a large jumble), sticks out
of the solution. Most of this is covered by a pink coloured, hazy
looking film.

I don't know what to expect, but so far this is what I have noted.
