Except that I *don't* drain it - that's the best part of CuCl is that it's air regenerated, there's NO waste at all. The copper in solution came from other boards I'd etched (you start with an HCl/H2O2 etchant and slowly convert it). _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
