Which consequence resulted from early cast iron cannon manufacture?

💡 Explanation

Impurities in early cast iron caused stress risers, thus thermal expansion from combustion increased risk of catastrophic failure via brittle fracture, because the tensile strength remained low. Therefore, cracking increased rather than internal ballistics improving.
