Stefan,
I never added cupric chloride and I always use fresh mix due to
safety reasons. I always have lighting fast etching and I always have
fumes and lot's of it. The fact that you have no fumes says that you
have a NEW PROCESS and I would try to duplicate it. You have
something so new that I checked your date if it is not an April Fool
joke. What you experience is not possible.
