There were more pictures to post, but you are limited to 3 uploads so...
Mark has asked me to add this:
1. This method should not be confused with the wet collodion method. You might do that by not seeing the missing photos. I'll post them in a subsequent set. They show noodle washing, chilling the plate and etc.
2. The hand technique as illustrated was used not only by amateurs for coating gelatin emulsions, but also in dry plate factories until the availability of coating machines. An 1884 account of the operation at the Cramer Dry Plate Works in St. Louis was described as "eight busy men, with pitchers of emulsion on one side, a pile of glass on the other and in front of them, a peculiar leveling stand." *
