Artificial orpiment, a new pigment in Rembrandt’s palette [PDF]
Heritage Science, 2017 This paper reports on how the application of macro X-ray fluorescence (MA-XRF) imaging, in combination with the re-examination of existing paint cross-sections, has led to the discovery of a new pigment in Rembrandt’s palette: artificial orpiment. In the

A SPECTROSCOPIC INVESTIGATION OF ORPIMENT (YELLOW ARSENIC) USED AS A DEPILATORY
Journal of Amasya University the Institute of Sciences and Technology, 2021 Orpiment in other name yellow arsenic, known as bath grass in public, is a sulfide mineral. Anciently, orpiment was evaluated as a pigment and dye in arts and industry for painting dolls and toys, and still is widely used as a depilatory.

Fast pH-Driven Solubilization Method of Realgar (As<sub>4</sub>S<sub>4</sub>) to Reduce the Toxicity of Arsenic [As(III)] for Medicinal Purposes. [PDF]
Adv Sci (Weinh)Arsenic trioxide transformed acute promyelocytic leukemia therapy and shows promise against HIV. A new method to solubilize the mineral realgar produces different arsenic species depleting the main arsenic target, nuclear PML protein, and retaining effects on leukemic and HIV reservoir cells, while minimizing off‐target damage.

Revisiting the Nature of Chemical Bonding in Chalcogenides to Explain and Design their Properties
Advanced Materials, Volume 35, Issue 20, May 18, 2023., 2023 Quantum chemical bonding descriptors enable a quantitative description of bonding in chalcogenides. These descriptors are employed as property predictors for optical and transport properties. Hence, they can be utilized to tailor thermoelectrics, photovoltaics, and phase‐change memories. Their unusual property portfolio is attributed to a novel bonding

Orpiment under compression: metavalent bonding at high pressure [PDF]
Physical Chemistry Chemical Physics, 2020 Orpiment (α-As 2 S 3 ) under compression reports a strong change in the coordination of As atoms at 25 GPa, which can be ascribed to an isostructural phase transition. These changes are consistent with the formation of metavalent bonds in orpiment.
