I have bought a bottle of liquid emulsion from Foma, and I am going to give it a try.
(And later I hope to use it for Bromoil)

Any advice how to store the paper for drying after I have coated it with the emulsion?

And how long will it take before it dries?
(Know it depends on the temperature etc. But as “starting point” as we say here on APUG :-)
