The discovery of an interface within the particle was entirely unexpected because ancient lake pigments are understood to be amorphous.24, 25 The LEAP tip closer to the particle's exterior is richer in carbon and methyl [‐CH3] with lead and oxido(oxo)iron as FeO2‐.

Results suggest that similarities with respect to time period and place of production may be developed among unprovenienced Faiyum mummy portraits to help localize workshops or artists, using analyses focused on lake pigments to characterize specifically metal‐based mordants. Figure 4B shows an image of the pigment particle following lift‐out of several TEM and APT samples. This service also requires a signature on delivery. The earliest known writing referring ancient mummy portraiture is a brief note in the elder Pliny’s Naturalis Historia, which dates to the first century CE.1, 2 The portraits from Roman Imperial Egypt, such as the example under discussion shown in Figure 1, Portrait of a Bearded Man, were intended to reflect not only the age, gender, and likeness of the individual, but the real or aspirational status of the subject of the portrait, both in his or her life on earth and anticipated rebirth in the next world.

Specifically, using a deft scalpel, an approximately 50 μm sample was carefully separated from the wax media and was then sandwiched between two glass slides, one having a convex recess to retain the particle.

A study published in 2013 in Nature Communications has shown their maternal lineage comes from a different, and possibly unexpected, source. Thus, the FIB, TEM, and APT methods were performed not only to characterize the microstructure and chemistry of the pigment, but to demonstrate the feasibility of using these relatively new techniques for what may best be described as effectively nondestructive due to the microscopic scale of damage left in the artifact.

Development dyeing is addressed in the Stockholm‐Leyden papyrus describing mordanting and dyeing fast purple: “if you wish the purple to be dark, add a little chalcanthus,” or chalkanthos, copper and iron sulfates.32 The presence of comparatively large lead carbonates in the outer layer suggests a period of digestion in an alkaline environment, such as that of the dye bath, where alkaline solution is used for dye extraction and stabilization.24, 25, Therefore, we propose that the purple pigment particle is actually recycled, or more appropriately, upcycled dye sludge, specifically the particulate residues remaining at the bottom of an ancient dye vat—solids recovered and repurposed to paint the mummy portrait, exemplifying resource maximization in Roman Egypt.
