Which outcome resulted from the historical transition to lost-wax “cast” bronze cannons?

💡 Explanation

Lower temperatures and more uniform bronze alloy within cannons were obtained due to the lost-wax casting method, which refined the bronze casting process; this decreased the rate of crack propagation under thermal stress because the material became more homogenous; therefore, the integrity improved with this mechanism, rather than being reduced because it created micro-voids.
