Which outcome resulted from early failures to properly 'season' newly cast cannon barrels during the Ming Dynasty?

💡 Explanation

Cast iron cannons required a seasoning process involving controlled firing to stabilize the metal—without tempering, internal stresses caused brittle fracture during high-pressure firing, leading to catastrophic explosions because of stress relief exceeding material strength; therefore explosions happen and rather than bore wear happening more likely.
