Point one .. why slop on the west wall block.??
The plastering was initially done along the gable joint above
The lower wall/ ledge slop would have occurred on either side of the joint. (messy job) (gravity)
The plasterer worked left to right along the joint.
therefore more residue on the cartouche block . (Think like spreading margarine).
the plasterer cleaned up the cartouche block maybe with a wet rag effectively coating most of it and some of the west gable block with thin plaster.
Same wet rag treatment on the wall blocks. It was a clean up job rather than an intentional paint job.
Point two.. Why did the plasterer not simply miss a patch in the region of the yellow.??
The yellow patch is prime virgin Giza limestone yellow as opposed to the brown yellow as seen on all the other blocks and just about everywhere else in Giza.
Anyway it does not make any difference to the series of events. the cartouche had to come after the plaster wash.. Unless of course someone can fathom a way of applying paint underneath a preceding coat.
Maybe I introduced some confusion here . apologies.
When I say "wash" I mean the spreading of pigment using mostly water.. as in a "water colour wash".
For the reasons mentioned. (virgin yellow) I suspect that the Khufu cartouche painter first wiped the very thin whitewashed surface with a damp rag before painting the cartouche. Thus revealing the yellow. A gypsum mineral based whitewash will be very easily removed by the over zealous use of a wet rag.
I feel that for various reasons, within this chamber, we have an amalgam of original masons marks. original drips and planar marks, various re-touched marks and one very questionable Khufu cartouche.
If the wall was whitewashed after construction then the cartouche was painted after construction, In situ, Obviously this has all kinds of ramifications concerning orientation etc. Not my field , I do paint, and I'm very good at it.
Apart from the Slop evidence I can think of no good reason for painting one surface of one block white before construction.
I feel sure that the cartouche was painted from top to bottom . I will not negotiate on that point.
Can I suggest you go through all the Dowell photos paying close attention to paint layers, flaking and chipping, Especially close ups of the cartouche block extremities.
The Dowell photos are good, do not be deflected into arguments about photo authenticity.
