|177. Tubular drill hole|
Tubular drill hole in an unfinished bead found from the bead pot (173) at Harappa. This unfinished bead with a tubular drilled hole suggests that bead workshops were still producing ornaments at Harappa during the Late Harappan Period, circa 1700 BC. The color of the carnelian suggests that it is not from Gujarat and the modified technology of tubular drilling indicates that the "Ernestite" stone drills of the Harappan Period were no longer reaching the site. The raw material used to make these drills has not been located.
