“…and to the New Kingdom (c. 1550-1070 B.C.) in Egypt show the use of polychrome effects within the same objects by using gold alloys with different colours [1][2][3][4] and sometimes native aurian silver [5]. A variety of gold colours could be obtained by adding Ag and Cu contents to gold from various sources.…”

“…With the development of metallurgy in 2nd millennium B.C., the beating of pure metal into ultrathin leaves, less than 200 nm thick, was developed and extensively used for “gilding” temple walls, precious furniture, and sculptures . Leaves of gold, silver, and copper having high purity were carefully laminated over the base stones, metals, and wood, for example, Tutankhamun's middle coffin as shown in Figure a. This coating process is ubiquitously seen in artifacts having various sizes and materials .…”

Gilding is the ancient process of coating intricate artifacts with precious metals. Fascinating Egyptian and Chinese sculptures, coated with <200 nm thin metal films by this process, have resisted corrosion, wear, and other environmental degradations for thousands of years. Here, 150 nm thin palladium leaves are enriched by doped with a single layer of graphene. Commercially available Pd leaves are uniquely suited for graphene synthesis by a highly dynamic chemical vapor deposition process. The Pd leaves made by high strain rate beating are stable at high synthesis temperature, resisting solid-state dewetting owing to their extremely low grain triple junctions density (0.017 µm −1 ). Mathematical models of growth kinetics guide the development of extremely rapid synthesis conditions, resulting in the formation of high-quality graphene on Pd in less than a minute, owing to the graphene grains growing twice as fast as copper-catalyzed growth. The graphene monolayer on the leaf increases the effective surface modulus by 59% to 236 GPa. Uniaxial strain testing with Raman spectroscopy reveals the excellent crystallinity of graphene by probing the stress-induced phonon shifts. This new material could open exciting opportunities in utilizing highquality 2D materials to coat large structures.

“…With the exception of studies by Schorsch [1] and Lucas [2], the main analytical researches carried out until recently concerned the collections of the Metropolitan Museum of New York: jewellery from the burial of Wah [3], jewellery from the burial of the foreign wives of Thutmose III [4], and a large set of aurian silver objects from the Ashmolean Museum of Oxford [5]. As a result, neither the goldsmithing practices in Ancient Egypt -alloys and manufacturing technologies -nor the origin of the gold was understood.…”

Abstract. 3D representations were made of a small Egyptian scarab with a gold band by a number of methods, based on photogrammetry and photometric stereo. They were evaluated for colour fidelity and spatial detail, in the context of a study of toolmarks and manufacturing techniques of jewellery in ancient Egypt. It was found that although a 3D laser scanner gave the best geometric accuracy, the camera-based methods of photogrammetry and photometric stereo gave better representation of fine detail and colour on the object surface.Keywords: Digital heritage, image acquisition, 3D imaging, visualisation, gold. Introduction and research scopeLittle is known about Egyptian jewellery dated to the Bronze Age and the practices of the goldsmith. With the exception of studies by Schorsch [1] and Lucas [2], the main analytical researches carried out until recently concerned the collections of the Metropolitan Museum of New York: jewellery from the burial of Wah [3], jewellery from the burial of the foreign wives of Thutmose III [4], and a large set of aurian silver objects from the Ashmolean Museum of Oxford [5]. As a result, neither the goldsmithing practices in Ancient Egypt -alloys and manufacturing technologies -nor the origin of the gold was understood. In 2009 however, two multi-disciplinary studies of the Ancient Egypt collections of the National Museums Scotland [6,7] shed more light on this jewellery and raised new questions on a very particular period of Egyptian history, the 2nd Intermediate Period (1650( -1550. This led to multi-disciplinary studies of other collections, including the British Museum [8], which applied elemental analysis to determine the composition of alloys, the origin of the gold and the evolution of practices for joining and decorating the objects.The CNRS PICS project 5995 entitled Study of Bronze Age Egyptian Gold Jewellery has involved exchanges between several French and UK institutions. The focus is on the origin of gold and composition of the alloys used for forming, soldering, and decorating, in order to provide new evidence on the technologies used in the Egyptian Accepted manuscript of paper.
