When it comes to putting size on paper for Gum prints, have you found brushing it on, using a small paint roller or dipping the whole sheet in a tray of size to be the preferred method?
When I first tied gum printing several years ago, I would immerse the entire sheet in a tray of warm gelatin and then carefully drag the sheet over the edge of the tray to remove some of the excess, hang and dry. I believe this is the method in the "Gum Bichromate Book" which was my only guide at the time.

I also vividly remember having to endure the burning eyes while using large amounts of formalin - maybe thats why my hair is white?

I saw Christina's post "I have not yet tried Kerik Kouklis' handy method of adding 6 drops of formalin per 10ml hot gelatin at time of brushing it onto paper which would probably be the ticket."

So, have more experience people found brushing smaller amounts to be a better way?

After some time away from printing, now that I have my darkroom back again, I'm ready to start again.

thanks for the help!
