Which mechanism increases when crucibles experience rapid cooling cycles in ancient copper smelting?

💡 Explanation

Thermal shock and spalling increases because rapid cooling creates differential thermal stresses exceeding material strength, therefore causing fracture, rather than improved chemical reaction rates which happen at higher temperatures.
