Bronze Casting

Abstract ATLANTIC 13B Alloy is a silicon bronze casting alloy offering excellent castability and corrosion resistance, good machinability and medium-high strength. It is an all-purpose alloy that is suitable for gears, valve parts and marine fittings. It is especially useful in stress-corrosion environments for thin-walled parts. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness and fatigue. It also includes information on corrosion resistance as well as casting, heat treating, machining, and joining. Filing Code: Cu-307. Producer or source: Atlantic Casting and Engineering Corporation.

Casting Production

The formation of the early bronze-casting production in Baraba and the appearance of products of the Seima-Turbino type were completed within the 3rd — early 2nd mil. BC — during the existence of the Krotovo Cul-ture. Plenty of work has been devoted to its characterization; the presence of bronze-casting on the sites has been noted, but special studies of this type of sources are extremely few. The purpose of this paper is to present the characteristics of the production areas associated with the processing of non-ferrous metals, based on mate-rials of the Vengerovo-2 settlement of the Krotovo Culture. Production sites were studied in six dwellings of the settlement. The uniformity of the workshops has been revealed in terms of site planning and principles of organi-zation of the production, although differences in scale have been noted. The use of two types of the forges has been recorded. In all these workshops and in other sites of the culture, a multifunctional sub-rectangular hearth buried in the ground with the walls and floor lined with fragments of ceramics or clay coating was found (with di-mensions of 1.65×0.87–2.3×0.9×0.21–0.52 m). The second type of the forges is less common — a small round or oval pit (0.4–0.5 m in diameter) with the bottom and walls lined with baked clay or fragments. The smelting was carried out with forced air supply. The casting of the metal was taking place next to the forge. Crushed bones were used as fuel. The production complex demonstrates extensive external economic and commercial ties. This is manifested by penetration of significant volumes of non-ferrous metal into the ore-barren areas of the Central Baraba, as well as by the presence of imported foundry equipment (molds made of marl and talc). The simultaneous presence inside the casters’ dwellings of bones of taiga-zone animals and those living in the southern, steppe regions indicates significant length of the supply routes. The specific features and unification of the production of the manufacturing equipment, nature of the work carried out, volume of heats, and a large number of similar-type forms suggest specialization of the village in the bronze casting production.

Bronze Casting

Almost half a century has elapsed since the first area excavation of a prehistoric site in north-east Thailand at Non Nok Tha (Bayard & Solheim 2010) (Figure 1). A long and still unresolved debate has ensued, centred on the chronology of the establishment of rice farming and bronze casting, that has dovetailed with further controversies on the pace and nature of social change. Results obtained during the past 20 years of fieldwork focused on the upper Mun Valley of north-east Thailand, together with a new series of AMS radiocarbon determinations from key sites, have thrown into sharp relief contrasting interpretations of two issues: one centres on the timing and origin of the Neolithic settlement; the other on the date and impact of copper-base metallurgy. A consensus through debate would bring us to a tipping point that would see Southeast Asian prehistory turn to more interesting issues of cultural change.
