Is you plate 110 degrees as well? If not the gelatin will try and set as
you are trying to make a smooth film.. As I remember I think Gelatin can go
to about 140 degrees before serious changes start to occur so you might
heat it up a little more, make sure your plate is up to temp and try it
again.
Actually if you have a hot plate ( read electric frying or cooking
skillet) with temp control you could pour a plate as you are now doing and
place it onto the temp controlled pan. This will make sure the temp is
correct and keep the emulsion fluid while you try to get the coat even..
When finished just remove it from the pan and let it cool.

A couple of hints here:
1. warm the emulsion in a water bath to about 110oF and it will 'flow'
around easier. By tilting the plate you should
be able to obtain a smooth and even coverage. With care you might allow
some to drip off a corner back into your
container.
2. Add a few drops of heavy whipping cream to your mixture. This makes for
a much smoother coating procedure. If
you think this is weird, it came from the Jobo newsletter a few years
back. If you wish, I can go to my archives
and try to resuscitate the directions .. but go for it. I'd say, from
memory, to try about 1/4 teaspoon for an 8x10
just to give you an idea.

Nothing as interesting as when is porn porn, the meaning of
postmodernism,weston's peppers and the value of contemplating women's
breasts. Just a mundane inquiry: I am trying to coat the metal plates
supplied by Rockaloid with Ag Plus emulsion. They recommend pouring a small
puddle onto the middle of the 4x5 plate and moaving the plate around so the
stuff is distributed, and using a finger to push it toward the corners if
necessary. Using a finger doesn't work at all for me-- and I am not getting
anything resemble even coating although the emulsion is liquified as per
instructions.I've tried a foam brush an d hake brush too, with very messy
results. I'm new to liquid emulsions -- are some better than AG Plus for
working on metal? or paper? All responses much appreciated.
Also -- could someone reind me about how one accesses the list's archives?
Thanks.
