Ancient Egypt stone machine faster Penetration rate ?! is based on an assumptions & ignorance
A functional analysis of the drilling of a granite sarcophagus lid from the Old Kingdom period
concentric lines were not always perfectly parallel & exhibited a slight amount of irregularity & aligned more closely near the bottom 4% narrow end & in a case devoid of lines,
Over a 24 cm length drill hole there was 1 cm. or 4% narrowing, 5.3 cm to 4.3 cm
test = constant 1000 RPM rotational speed of held intermittently at constant pressure
Granite is composed primarily of quartz (7), feldspar (6) with some mica (2-3).
Emery is a granular rock composed mainly of corundum
corundum is a crystalline compound of silicon and carbon—magnetite and spinel
abrasives tested =
beach sand , crushed quartz , & garnet =7, emery ,corundum , & silicon carbide =9 , diamond (10)
fixed abrasives or those in a watery slurry or a lubricant such as olive oil did produce concentric cutting lines; BUT loose, dry abrasives (except diamond) did not produce concentric lines
ancient Egyptians were aware of the value of water as an aid to drilling, the presence or absence of concentric lines is an indicator of the type of abrasive used , emery, & corundum used loose with water, olive oil or a viscous lubricant created a drill hole faster than when only water was used, & Only diamond produced concentric lines when used loose and dry. but Pliny the elder said emery or Noxium was available from Noxos.
rock softens & melts at 1200 c & air blasted coal burns at 1927C
