Now that some sheets of 4x5 glass have been secured they must be cleaned. The edges were ground round so that I would not get sliced any more. This step must not be neglected. The grinding was done in a bucket of water so dust was not a problem. However, removeal of old emulsion and grinding of edges does not clean the glass.
Instructions were sought:
The Light Farm has an article by Bill Winkler
Liquid Light has an instruction sheet
alternativephotography dot com has an article on Dry Plate Photography (googled)
The CD book: Dry Plate Photography, by towler 1865, chapter I, Preparing the Plates, 10 pages
They are all different. There is everything from using your finger tips and detergent to grinding and polishing the glass then using sulpheric acid!
Those four sources were all printed out. Now to read them and choose a method.
