[Loris Medici]

Thanks much Rajul. It seems you have worked pretty hard, formula is complex.

- What is the purpose of UV'ing? (I don't see anything in the ground that
will crosslink with UV. Could be my ignorance perhaps?)
- I understand that you "roll" the tube in the first pass then "push" back.
I may try this coating method; sounds promising for my needs...
- Did you notice any adverse effect to the cyanotype? (Such as: weak dmax
and sensitivity...)

Thanks much again!

Regards,
Loris.

...

Ground mix:
  			20g Stevenson's Acrylic gesso
			50 ml water
			 25 ml gum arabic (I use Senefelder's)
			 50 ml Gamblin PVA size
			 15 g sieved Sand Flour ( I sieve it through fine
nylon mesh)

...

Coating of the mix is done with ~1" diameter plastic tubes that are 11"
long. I pour about 10 ml. of the mix along one edge of the plate and roll it
back with the tube to the closer edge, then gently push it to the opposite
end till a thin, even layer is obtained. This is dried with a hot hair
dryer, allowed to air dry overnight, then UV'd for 2'.
