c8.27

Alabaster, limestone, quartzite, slate, and jasper are among the other stones which were used to make weights; but chert predominates and was always used for the cubical type. The stone was first roughly flaked into cubes, then rubbed down smooth upon an abrasive, and finally polished. No weight has been found with a number or any mark upon it, with the exception of one barrel-shaped specimen which bears two pittings, but these may only have been made to rectify its weight. Pebble weights are also known, but they are very rare.
