Which consequence resulted when highly-ornamented medieval astrolabes experienced excessive handling and polishing?

💡 Explanation

Excessive polishing of astrolabes caused material removal, causing markings becoming obscured due to abrasive wear; therefore declination readings were lost, rather than expansion or damage, because these depend on different conditions (temperature gradient and stress beyond limit).
