Vlad,
In English it is "Collodion" and it is the actual substance, I believe made from egg whites, that the silver nitrates and other sensitizing chemicals are combined with so that they can be coated onto the plate. So it is a thick viscous liquid. Sometimes the plates coated with it are called "collodion plates". They are wet plates, I believe, and are used while still wet. Once the gelatin was used instead, then it could be dried and so they became dry plates.
The albumin paper was for printing from both kinds of plates and albumin was also from egg whites and was also replaced by gelatin, and then we have 'silver gelatin' prints up to modern times.
Regards, Bill
