Which early consequence resulted during crucible bronze production if Mesopotamian furnace temperatures fluctuated significantly?

💡 Explanation

Improper temperature control during bronze melting caused *constitutional supercooling* in the alloy, therefore tin concentrated in the last liquid to solidify, rather than achieving homogeneous composition after cooling because of imperfect heat flow, and inducing segregation.
