Given by the properties of neutrons to penetrate and to visualize macroscopic samples, the study of cultural heritage objects is nowadays a commonly used option next to X-ray investigations. In particular, their higher transmission through thick layers of heavy metals and the high sensitivity for small amounts of hydrogenous materials enabled the study of historical artifacts with respect to...
Cold neutrons are slow‑moving neutrons with relatively low kinetic energy. They are produced by passing higher‑energy (“thermal”) neutrons through a cold moderator—typically liquid hydrogen or liquid deuterium cooled to cryogenic temperatures. Because they move more slowly, cold neutrons have longer wavelengths, which is highly advantageous for the use of various neutron‑optical components...
Neutrons have attracted considerable attention in cultural heritage due to their distinctive features. This study showcases the utility of neutron-based analytical techniques for the non-destructive internal examination of historical metallic artefacts. Two objects (dating from the 17th to 20th century) from Guangdong Museum—a sealed gilt‑copper Buddhist statue and a standard weight—were...
To accurately analyze the internal structure and craftsmanship characteristics of unearthed cultural relics, high-precision CT imaging detection and 3D data processing were carried out on four ring-pommel Daos samples of the Western Han Dynasty unearthed in Yangzhou, China. Through detection and identification, three of the four ring-pommel Daos had surviving scabbards, and one was an...
The history of technology of ancient civilizations is mainly the history of their metallurgical capabilities. In fact, metal tools, weapons and art objects were produced using the most advanced knowledge developed by the different civilization, since metalworking requires a wide amount of technical skill and empirical knowledge of complex thermal and mechanical phenomena. Ancient metal...
