Subject: [Homebrew_PCBs] Oxygen regeneration of CuCl2
From: Mark Lerman <mlerman@...>

If I add 3% H2O2 to regenerate my etchant, I'm adding a lot of
water to the mix, so I'm wondering if there's any advantage or
disadvantage in bubbling oxygen rather than air through CuCl2 etching
solution? Or does the air itself regenerate the solutionadequately in
addition to agitating it?
