Space and time constraints usually limit me to coating 12-20 plates at a sitting. For this reason, I only wash the amount of stock emulsion that can be used within 24 hrs, melt what I can coat at one sitting, and keep plates refrigerated if I'm not going to be shooting them within a day or two. I'm in the habit of adding an anti-foggant (TAI) to every batch to lessen any "after ripening" during storage.

Comes the happy day when I can enlarge my lab area, and not have the distraction "regular work", I'll be able to scale-up the process.
