Oil Paint
Hi,
just read your document on FAQ's etc, in regard to sinking in of the umbers, apparently because of their clay content (PBr7 from natural iron oxide ore).
(1) I have just noted that W & N make a similar colour, synthetic iron oxide PR101 (transparent brown oxide) which has, apparently, micronised pigment particles which I doubt would contain any organic substances such as the problematic clay referred to above? If I use the latter should I then avoid the sinking in associated with PBr7? (all other things being equal);
(2) If I use an oil-based primed canvas such as lead white (instead of an acrylic gessoed one) would this stop the sinking in, even if I use PBr7?
Many thanks in advance
