Emulsion making is now being studied. Much material has been looked over; lots has been printed out; several reads of several parts have been done. Two sites are being explored and mined for data. One is The Light Farm, and the other is in APUG, Emulsion Making and Coating, the stickies.
It took a while to be able to even print out anything. I had to learn how to use several different computers, programs, and methods of printing to get hard copies. That was fun because I used to be a graphic artist and it came naturally.
There are other sources on the web, but they are not being used; there is so much on the two sites listed that I'll find what I need there. What I need is a selection of recipes and materials to the end of getting the most basic and simplistic way to make an emulsion. The idea is to be able to make emulsions in Middle School, where I used to teach art.
The study of how to make emulsion has begun now because preliminary work has been successful. Several beautiful plates in ULF (larger than 8x10 inches) have been made and many in the 4x5 inch format. Cameras, lenses, plate holders, tripods, and lenses have been collected, fixed, and I learned how to use them well enough to get good images. Put light meters in that list, too. A darkroom was constructed, stocked, and used. Finally, plates were coated. That took a while to get hold of.
Now I want to learn how to make my own emulsions. Before I buy new lab equipment I want to be able to make emulsion the primitive ways. I saw an article like that somewhere, I think it is on The Light Farm, about sea water ...
