Which evidence can confirm that a metal object was polished after casting?
Answer and explanation
Correct answer: Partly removed casting seams and fine abrasion marks on the surface
The governing principle is that finishing processes leave marks directly on the artefact. Grinding and polishing can partly remove casting seams and produce fine, oriented abrasion marks on the surface; together these are direct evidence for post-casting finishing, so option A is correct. Weight does not prove polishing, while ore and furnace bricks show metalworking activity at a place, not finishing of this particular object.
