This method was termed by Stocks 1993 as the Twist-Reverse-Twist Drilling TRTD method. The experiment in vessel making starts with the shaping of a block of limestone with copper chisels and adzes, flint chisels, punches, scrapers, and rubbers made of sandstone. The rough shaping of the vase took about 6.5 hours.
Rural Egypt is undergoing a process of socio-economic transformation which has made a great number of rural agricultural workers redundant. These seek work in non-agricultural occupations in villages and fast-growing cities. The limestone industry is a major source of non-agricultural income in the villages of the east Nile in Middle Egypt.
Limestone quarries. Limestone is often produced using opencast mining methods through a multiple bench system, although excavated quarries can also be found via underground mining. Typical operations include drilling and blasting, both designed with a specific fragmentation curve in accordance with the final product to be achieved.
Hammamat,Eastern Dessert. Gold mining started with alluvia l workings in Egypt and was followed by shallow underground vein mining in Nubia about 1300 BCE, during the New Kingdom period. The methods of working included fire setting to weaken rocks by thermal schock, a method described by Diodordus Siculus in his Bibliotheca historia written about 60 BCE.
