The innovative system of control by weights and measures distributed by Umayyad and Abbasid authorities also included heavier weights, produced at the same official glass workshops as coin weights and vessel stamps. These heavier weights usually took the form of large glass disks or heavy glass rings, made by folding thick bars of viscous glass. Glass rings could be suspended from a string. Due to the thick, hot, viscous material of these larger objects, the inscription of the stamp is rarely clearly legible. This one names the calip al-Mutawakkil ‘ala Allah (r. 847–61) and has the weight of a ratl.
