Evidence
"Of particular note is the sophisticated application of azurite in the Prophet biography, in which we encountered three hues of blue... a shade of blue where a yellow or green glaze was placed on top, applied to create shadow and give volume to the letter."
Remarks
Extensive detachment from the support was observed, likely due to larger grain sizes which provide less surface area for contact with the binding medium (p. 8).
