Certainly would be consistent with the claimed 40,000 stone vessels at the Step pyramid since the majority are made of travertine (limestone) followed by metasiltstone and limestone breccia...... the rest made of other rocks in which Aswan granite is down the list just ahead of dolomite, marble, serpentine, aragonite, and quartz (Lauer 1976), and the vast majority of those are small jars and such (El-Khouli (1978).
