Carrying out the second phase of the project took more than 7 years engaging the new members of Reza Ziaei’s Workshop.

ehrouz Mohammadi, “Daf and its feasts in Ghaderieh’s Tekyeh” mentions that the outer thickness of arch where studs are located, [is] between one to one and a half centimeters (Mohammadi, 2001: 12).
