While developing plates it was more difficult to spread the developer over the plates.
Of course you can solve it by adding a little alcohol to your developer but on a certain point that won't help anymore
So it was time to start maintenance of my silver bath.
I didn't had any other problems so I decided just to boil the solution back to a volume of about 90%. As a matter of fact, just heating up the Silver Nitrate is even more than enough. You only need to get rid of the Alcohol and Ether which came in with the Collodion.
Alcohol already boils at 79 degrees Celcius and Ether already at 35 degrees Celsius.
make sure you boil the silver solution in a stainless steel pot and in a very well ventilated room or outside.
After doing this I add the needed volume demineralised water and the bath CAN turn VERY cloudy.
Don't worry about that. It's absolutely normal and has nothing to do with maybe a bad quality of Demi water.
Just shake the bottle and leave it that way for a few hours it will clear and you will see a lot of dirt at the bottom of the bottle.
After that I sunned the bath under a face tanner. filtered it twice, checked gravity, added the needed silver nitrate and it was ready for use again.
Result : a perfectly clear and good working silver bath again.
So it takes a few hours but the result is worth it.
There is NO need to iodise your Silber nitrate again. It's ready for use
NOTE: I have been working with the "same" silver nitrate bath from the start in 2009. I NEVER added anything except silver nitrate and water. So No acid, no Clay no NOTHING.
If you treat your Silver nitrate with care you can work with it for many years!
This is absolutely normal
