Recipe Details
Ingredients
Natural cinnabar
Preparation Steps
The red pigment is natural cinnabar (HgS). Trace elements identified by XRF (nickel, copper, zinc, silver, gold, thallium, and chromium) suggest a natural origin, possibly from the mines of Almaden in Spain (p. 10). Reflectance spectra show an absorption edge nearing 550 nm and inflection points at 596 nm (p. 10).

Evidence
"XRF main signals correspond to mercury (Hg) keys, while Raman spectra show the cinnabar HgS characteristic feature at 344 cm-1"
Remarks
The pigment is used for vocalizations and decorations. The similarity between spectra on both manuscripts indicates the same source (p. 10).
