The oldest examples of glass discovered in the tombs of Egypt and Assyria are in the form of beads, scarabs, amulets, etc. for personal decoration, while glass objects such as bottles, cups and vases came at a later date.In Egypt, the first glass we know of, as a component of faience ware, dates from as far back as the Neolithic Badarian culture at the turn of the 5th and 4th millennia BC. Glass is produced from a mixture of silica-sand, lime and soda, colored with the copper ore malachite and fused at a high temperature.

Efficiency: Once users have learned the design, how quickly can they perform tasks?
