[Guido Ceuppens]

I use 1 part casein/paint + 1 part saturated Pot Dichromate. I use
acrylic colors as well as powdered pigments in a "heavy" mix and do
not bother about transparency of the colors, I like (at least at this
moment) very colorful and saturated images, development is sometimes
carefully but most of the time very vigorously with brush or even
sponges.

> What an easy formula, Guido. I see it is about a 14% solution. Do you combine that equally with dichromate? Are you still using acrylic colors in the mix or powdered pigments?
