Do you have a step by step method for using Gloy.
Jack
It's in the Silverprint Manual.
But here goes.
1.Treat the Gloy as if it were gum arabic but you will not be able to
develop 'automatically'. But then I have never seen the point of doing
that anyway.
2. Use saturated ammonium dichromate 50/50 with the Gloy.
3. Use Winsor & Newton Water-colours from the tube.
4. Method.
a mix strong watercolour, where you need little pigment to get a lot of
colour, on a plate to get colour you want.
b mix in the gum ( this will give you the tonal range as on the page)
c mix in dichromate
d coat paper with hake brush or water-colour lacquer brush
e dry in dark
f expose, between sheets of quarter inch float glass or whichever method
you prefer. for highlights for about eight minutes at 18 " from a HPR 125
MV UV lamp.
g develop in water with hake brush or water jet.
h dry and repeat a to g but with more pigment for the middle tones and an
exposure of about two minutes.
i repeat a to h with more pigment for the shadow detail but with an
exposure of about 1 m 45 s
j leach wash in a dribble of water with the print face down and weighted
with pennies until the dichromate is washed away to restore the colour you
first thought of. Use bisulphite to clear if you wish but then you have to
wash out the bisulphite. And anyway it makes me cough all over the place.
If you use Fabriano 5 or Bockingford you should be able to complete these
processes without sizing the paper first. When I size for other papers or
between coats I use hot 2 or 3 % deionised ossein which I also use for
sizing paper for platinum (!%). The size is dried in hot air from a fan
heater before the next coat is applied. I do this if I want absolute
consistency if I am working on commission. Using paper sized first with
tanned or hardened gelatine is also fine. .
Banks of fluorescent tubes at six inches will give shorter exposures but
the results, I feel, tend to lack something in subtlety .After all the HPR
lamp is designed for the purpose.
In my experience my method gives more subtle and richer results with far
greater control and consistency and less effort than the methods included
in the standard manuals.
There is a chapter on this method in the Silverprint Manual and the new
manual John Barnier is editing. It will also be covered in my own new
manual 'Alternative Processes: A Clear Explanation' or some such title.
That will include more detailed explanations of the whys and wherefors than
this very short explanation.
Hope this helps.
