Rockin' Around the Christmas Tree

I've been plagued with silver bath issues for the last few weeks. I think I've found the issues. I was using too much acetic acid to re-acidify my baths after heavy maintenance consisiting of sunning, filtering, neutralizing, and a boil down.. After rehydrating/re-silvering back to the same volume, you then have to make sure the PH is around 4 to 5. I've been using acetic acid, but do no think it is strong enough to get me where it needs to be, I've been putting too much in and it was contaminating the bath. So I took the plunge and dumped half a batch of silver and added in freshly mixed silver and it worked flawlessly for the first two plates...Will try a few more and take some pics of some new toys..

Looking good Andrew .... Glad to see you fixed your Ag bath issue ...
 
Andy, FYI in seven years of doing wet plate the only thing I've ever done to my silver bath is sun, filter and replenish. I always check the pH but have never needed to add acid.
 
thanks Kerik.... I realize I was probably causing myself the problems by over complicating the process... that said, I was doing the boil downs to remove the alcohol/solvent smells from the silver bath and to get around developer flow issues. I had read that neutralizing and sunning prior to the boiling step would also remove more free iodides.. By necessity, re-acidifying the bath is needed to bring it back to normal... I will not be doing the neutralizing anymore until I absolutely have to.
