Soot experiment IV - step IV... Slowly gravitating towards fully saturated colors...

For the fourth coat, I decided to go with fluid transparent washes to introduce some nuances...

Another coat will be required to get the darks and nuances I'm after...

Note: I'm developing two sets of techniques in parallel: 1) the use of black soot and/or brou de noix as a substitute for paint in the creation of  full-blown images 2) The optimal use of paint over underpaintings made with soot and/or brou de noix. Ultimately, I'd like to mix and match these techniques to create images that show characteristics associated with charcoal drawings, old photographs and contemporary art (drippings, splashes, textural effects, etc...).
