Production of arsenical bronze using speiss on the Elephantine Island (Aswan, Egypt) during the Middle Kingdom (Middle Bronze Age) (c.2000–1650 BCE)

open access: yesArchaeometry, EarlyView.
Abstract This paper presents the first direct evidence of the slags produced during the cementation alloying process of Cu with speiss inside ceramic crucibles, thus representing Cu alloying with As in Middle Kingdom Egypt. The settlement deposits from the Middle Bronze Age were excavated on Elephantine Island, within modern Aswan.

Archaeometric Characterization of Submerged Sasanian Stucco From Ghaleh Guri, Western Iran

open access: yesArchaeometry, EarlyView.
ABSTRACT The Ghaleh Guri archaeological site, a late Sasanian site with a building complex dated to 591–628 ce, lies along an ancient road linking the western Zagros to Mesopotamia. Its architectural remains, adorned with stucco, faced annual river floods yet remained stable for centuries.

Pechini synthesis and microstructure of nickel-doped copper chromites

open access: yesMaterials Research, 2005
Spinel-type solid solutions were synthesized by the Pechini method and calcined between 500 and 900 °C for 4 hours and at 900 °C for 8 hours to produce ceramic pigments.

Medicine for the Material World

open access: yesArchaeometry, EarlyView.
ABSTRACT It is clear that many of the inorganic materials of antiquity have been used both as medicines for human ills and also as agents in technological processes. This paper speculates that there might have been a stronger link between these two functions in the past, based on the concept of “active agents”—materials that are efficacious at curing ...

New outlooks on ceramic pigments.

open access: yes, 2003
The recent advances concerning the processing and the physico-chemical properties of ceramic pigments are reviewed, focusing on innovative technologies and crystalline structures no formerly proposed for colouring ceramic wares. In particular, new insights into the colouring mechanisms are outlined as well as the design, characterization and use of new

Evaluation of physical, chemical, and color‐matching properties of monochromatic resin composites: An in vitro study

open access: yesEuropean Journal of Oral Sciences, EarlyView.
Abstract The objectives of this study are to evaluate, in vitro, the microhardness, sorption, solubility, color stability, and color‐matching ability of monochromatic resin composites: Palfique Omnichroma / Tokuyama (Mono1) and Vittra APS Unique / FGM (Mono2) compared with the conventional resin composite: Filtek Z250 XT / Solventum (Conv).
