The "ice cube" from You are not allowed to view links. Register or Login to view. is blue vitriol.
Or Cu SO4 5H2O-- blue colour.
And the yellow heart is the sulfur, contained into it. In Alchemical theory vitriols are understood as combination of metallic
principle ( copper blue) with sulfurous principle (yellow).
In an era before standardized chemical names the blue colour had been a clear identifier. Just as green vitriol meant iron sulphate , or white vitriol - zink sulphate.
Also it is due to note, that in the medieval pharmacy after purification (elimination of toxicity) the blue vitriol was highly used in skin, eye, brain etc. diseases.
Given that folio 102v resides in the pharmaceutical section of VM, the identification that this cube is blue vitriol rests on strong circumstantial evidence.

Which analysis are you referring to? Not the McCrone report?
The evidence for late coloring is the folio number on page f42r. According to Rene and another person who looked at that number with a microscope, the green paint is sitting on top of the ink of the number. And it seems to be established that the folio numbers were written after the bifolios were bound (in the wrong order), a century of more after the text and drawings were made.
All the best, --stolfi

Register or Login to view.The Mc Crone analysis was a prove that the pigments are authentic to 15 century, this refutes the claim that they are 20 century edition and also the person painting them might have not been ignorant of their meaning.
Quote:Crucially the paint transferring of facing pages proves the colors were applied while the manuscript was bound.
