Which risk increases when an astrolabe is produced via lost-wax casting?

💡 Explanation

In lost-wax casting, metal **shrinkage** occurs during cooling; small uniform contractions are tolerable, but nonuniform cooling could affect angular accuracy rather than other considerations, because this mechanism distorts the astrolabe's geometry; therefore, measurement errors increase rather than issues like metal fatigue or creep, which would be more tied to operational stress.
