소방 관창(消防管槍) 유물의 보존과 재료학적 연구

초록

Fire-fighting culture heritage refer to tangible items and materials that contain storiesrelated to fire-fighting. Among the fire-fighting items, the nozzles, which play a large part inextinguishing fires, are of great conservation value because few of them are left as culture heritage. In this study, conservation treatment was performed while observing the surface and corrosion stateof two nozzle culture heritage used for fire-fighting. The processes were recorded by reflectancetransformation imaging technique. In addition, the material characteristics were examined throughobservation of surface microstructure and component analysis of a total of 3 samples, including 2of these relics and 1 of recently produced nozzle. As a result, it was confirmed that most of the ruston the nozzle surface was atacamite, and that nantokite remained partially. The base metal of the nozzlewas presumed to be red brass among the types of brass, considering that it contains Cu as the mainelement, 2 to 15% of Zn, 5% or less of Sn, and 8% or less of Pb as additional alloying elements. In addition, the crystal segregation did not disappear and the solid solution was generated as aheterogeneous dendrite, indicating that the brass casting used as a fire nozzle was rapidly cooled.
