Joe,
It is ammonium dichromate and I am using an 1160. OK on the questions, you
and I are in the same boat, lets keep up the discussion. If this gets
tiresome for the list we can take it offline.
I've done a second print with the burnt siena gauche and a second coat of
lamp black gauche, I dont think I was supposed to use gauche for the second
coat or the first for that matter for a multi coat print but it was a large
improvement over the first print.
You know I've been a sworn piezo user (and still am) but I really missed
hand making prints, I've had a thoroughly enjoyable day.
