← HistoryWhich outcome followed inefficient blast furnace setup during early cast iron production within the Han Dynasty?
A)Increased carbon concentration
B)Consistent silicon distribution
C)Reduced crystalline grain size
D)Formation of white cast iron✓

Formation of white cast iron arises when rapid cooling follows casting because cementite is favored over graphite precipitation, therefore hard, brittle white cast-irons develop rather than more workable grey irons, resulting in inferior tools.
