Thanks very much.

>FAEW is very white, perhaps you go the off white.

On the packing slip it says 'extra white'. When I compared it with some Arches
(rough) that I had, it just wasn't as white...:(

Basically I'm scared of hot formaldehyde, plus, I can put any surplus jelly in
the fridge 'til next day if I need to.

I will.

>What is your pigment/gum/dichromate ratio?

5 ml. gum:6ml. Sat. Potted Dich.: large pea sized squirt of pigment (not very
scientific I know :( )

I had a big problem with getting an even coat that was rich in pigment but not
too thick. I devised a method (of sorts ) and it works well for me. Mix the stuff
as normal, then slap it on the paper with any old brush and spread it around.
Then the magic bit. I slightly damp a sponge roller and take the excess off agin
by rolling and applying a firm pressure on the roller. The excess soaks into the
sponge and the roller evens out the brush strokes. I then leave it for say, a
minute, then buff to a shine with a couple of hake brushes. It really works well
for me. Of course you more experienced gum printers can get a thin coat with only
a brush I know,but for beginners or people with stellar ineptitude scores like
me, it gets a result.

Thanks,
