Homebrew PCBs

Hello,

I've been experimenting with toner transfer for a while now, and I'm 
starting to see acceptable results. This group has been a great help 
in my endevors.

I read some posts in the archives about recycling (revitalizing might 
be a better word) Feric Chloride etchant.

As I read the instructions, using two iron nails as electrodes, run 
about 1 amp through the solution. (more details would have been 
helpfull)

I tried this and my results were less than stellar. The negative 
terminal collected particulate copper (kinda looked like a sponge, 
but just dust, wiped off easily) and the negative terminal did erode 
some (about 1 hour). In the end my etchant looked like brown mud. 
Then I tried etching with it and it seemed slower than before I did 
it.

Perhaps sombody could advise?

Thanks,
Denny
