Which outcome results when bronze smelting lacked precise temperature control around 1200 BC?

💡 Explanation

When bronze smelting lacked temperature control, the inadequate control results in excess oxygen incorporation because a stable oxide layer is not effectively removed, leading to brittle bronze. Therefore metal embrittlement results, rather than fuel inefficiency, slag reduction, or crucible cracking, which depend on furnace design rather than metal purity.
