Squat Jar with Lug Handles, 2950-2573 BC. A single tomb might contain hundreds of stone vessels replicating the shapes of pottery vessels used in everyday life. The most popular material for stone vessels was white or banded travertine (Egyptian alabaster), found close to the Nile, but prospectors and quarrymen often traveled far in search of the desired materials. The hard stone hornblende diorite, notable for its mottled texture, was quarried in the desert along the route to the Red Sea.
