Which outcome followed early use of bellows-driven blast furnaces in ancient China to exceed ~1150°C?

💡 Explanation

Creation of cast iron resulted because sufficient temperatures were reached to melt iron fully; the absorption of carbon via carburization allowed for lower melting points therefore promoting liquification rather than retained wrought strength.
