The workshop was all about pulp painting. I'm not talking about just squirting overbeaten pulp from a ketchup bottle onto a freshly pulled sheet of paper (although we did that). She talked about the chemistry of it all (and made it interesting). She demonstrated how to color the pulp with pigments and retention aid so that the pulp was really highly saturated. We then each had to try to match a paint chip so that not only was the color correct but it didn't bleed either (sounds easy, it's not). Then big fun: using stencils, paint brushes, titanium white, dental syringes, spoons, cups, ketchup bottles, spray misters and other tools, we experimented. Into the press and then voila, finished masterpieces. Ok, I'm getting carried away. No masterpieces maybe, but all good tries anyway.
Here are sample colors. I mixed the orange. You can see how the bottom left blob is bleeding so more retention aid was added until the bleeding stopped.
