Bulb III

A quick plate from today as I was in the Studio picking up a few things.

The Ernemann 5×7 holder is looking a little worse for wear of late. The metal septum has been slowly eaten through by the Silver Nitrate. Corrosion around the edges is producing some worrying effects to my plates. There are lots of silver islands? that I just cant seem to get rid of. The silver bath has been sunned and filtered, the pH and SG are both correct. So I can assume its the holder and its holes thats causing the issues. When I get chance I’ll post up some images of the corrosive qualities of AgNO3.

Here you go…
