Passage:
During the early Levant Bronze Age, the transition from unalloyed copper to arsenical bronze marked a critical shift in regional metallurgy. Early smelting workshops relied on localized copper ores with variable arsenic impurity levels. Scholars initially hypothesized that early smiths deliberately added arsenic-rich minerals to enhance the metal's hardness. However, recent isotopic analyses of local slag heaps indicate that furnace temperatures were insufficient to volatilize arsenic from secondary mineral additives. Instead, the presence of arsenical copper in early artifacts corresponds directly to natural variations in the mineralogical composition of localized ore strata extracted across distinct mining phases.
Later in the period, the adoption of tin bronze necessitated long-distance trade networks, as usable tin deposits were entirely absent from the Levant. Unlike arsenical copper artifacts, which varied in composition according to local ore layers, tin bronze objects from this later phase display a highly uniform ratio of tin to copper across distant urban settlements. Archaeologists attribute this compositional standardization to the emergence of centralized municipal authorities that managed the procurement and distribution of imported tin. Consequently, while the composition of early arsenical copper was governed chiefly by regional geological variation, the consistent quality of later tin bronze depended on institutional mechanisms for managing external trade.
Based on the passage above, is the following statement True or False?
Statement: The contrast in compositional consistency between early arsenical copper artifacts and later tin bronze artifacts reflects a transition from metallurgical outcomes governed by localized geological variations to those regulated by centralized institutional distribution.
