I know that there has been much dispute over the geopolymer theory of Dr. Davidovits regarding the pouring of stone blocks used in the construction of Egyptian pyramids. It seems to me, however, that Davidovts' proposal that some of the AE stone vessels could have been crafted using a geopolymer technique is both culturally appropriate (i.e., an ingenious use of available materials) and credible.

Surely the mortars which they used alert us to the existence of a sophisticated knowledge in cement formulations during the OK period.
