Regarding Joseph Barabe's talk, the copper content in the ink from the text example on 26r looks to be very low, and this is consistent with text on 78r - not the whole ink test, just copper. The amounts of copper jump substantially on the painting outline ink taken from 26r, which Joseph notes as "significant". The ink again goes back to very low amounts of copper on 70v taken from the drawing of a nymph. 

Might this be caused by the sample being contaminated by the green paint? There doesn't look to be any real boundary between paint and ink, so I would assume it would be a mix?
Joseph said regarding the green paint that he suspects part of the process to make the green paint was by treating copper. As you can see in the images its copper content is high.

 - Thank you for the talk everyone involved, it was interesting and enjoyed listening to everyone's input. 

Copper is shown "CU" in images.
