Re: VMs: Researching the VMs at Beinecke

Hi Nick,

Unfortunately, I am not knowledgeable enough to identify these colors at this time. The contamination (sawdust?) in the bright colors was unexpected. The colors used by scribe-2 (the apprentice?) seemed to be the purest/cleanest. BTW, not of the colors struck me as being water colors or crayon colors; however, again, I am reallhy not qualified to judge paint color and chemical makeup.

The colors of scribe 1, 2, and 3 (or A, B, C) all each different. The text color of scribes 1 and 2 is brown and for 3 it is black. The blue used by scribe-1 shows considerable texture and I was impressed by its sparkle when lighted under magnifying glass. This suggested to me that there is gum arabic (?) used in the paint.

Are you sure this isn't simply ultramarine blue (ground lapis lazuli) or azurite?

You can (of course) tell these apart by Raman spectroscopy:-

Ultramarine comes from a land far from the sea (why of course it does) - but did you know that the land in question was Afghanistan? :-)
