Screening in DA is always inspiring for me...
That's just me. I think you could scale up with the graphite wash.
There are a couple of ways to do graphite wash. There are solid sticks and tins that you apply like water-soluble colored pencils or pans of watercolor. I've been using powdered graphite mixed in water. In this piece I used a foam brush.
It does not take much graphite in a small amount of water to make the wash.
It would need a little experimentation to get the molecular distribution in a continuous field to correspond to the desired membrane transparency.
The support seems to make a significant difference in how the wash behaves. This piece is on rough, heavy watercolor paper. The paper absorbed the water quickly and left a nice, thin layer of graphite. It was easy to build up layers. On other paper, the water sits on top longer. On primed mixed-media board the water doesn't absorb much at all. The advantage of this is that allows time to move the graphite around with a brush or tilt the board to make it run/drip. The graphite layer is fragile especially in heavier applications so I've been using a workable spray-fix as I build up layers.
Uh-oh . . . I've done it again -- you asked me the time and I ended up trying to explain how to make a watch.
Hope this help.
Hi Ken, thank you for all the details of your novel tool. I will try to get the material in a Berlin art storehouse who have nearly everything... and to start experimentaion using your „manual“.
Why I asked for the size: I visited several of the private Art Galleries in Berlin (estimation: more than 100). As most of them are hanging large paintings (>1 qm) I asked for the reason. Some of them told me that they pay not for the effort but mainly for the size of a painting. Nevertheless it will be easier to sell smaller ones -> price !!!
To be honest, I am painting for myself and not for cash. However, in the meantime I have problems to store the many pieces, and consequently I switched to smaller size and to paper instead of canvas. Nevertheless, it would be fine to take away as much as possible...
All the best, Helmut
Got a few new colored pencils recently (Caran d'Ache Pablo, not enough difference from other colored pencils to justify the higher cost, in my opinion. I reserve the right to change that opinion pending more use.).
I was doing shading samples -- runs of dark to light -- and it occurred to me that it was similar to a musician practicing scales.
