Which technological consequence resulted from the limited availability of high-purity copper during the Bronze Age?

💡 Explanation

When high-purity copper was scarce, alloying practices changed as metalworkers compensated for impurities via optimized proportion of constituents which shifted metallurgy towards higher tin content to improve hardness and castability. Therefore increased tin content results, rather than iron tools, trade decrease, or advanced casting, which require distinct resource availability and societal shifts.
