Geopolymer technology for casting artificial stone lost and rediscovered four times

Geopolymer technology for casting artificial stone lost and rediscovered four times. Marcel Foti's 'Natron Theory: proposes ancient cultures knew how to cast artificial geopolymer stone According to Foti, this geopolymer technology has been lost and rediscovered at least 4-5 times in human history The four versions of geopolymer evolution: 1st version are megalithic stones from early Stone Age; Egyptian pyramid blocks represent the 4th version

Marcell Foti's Natron Theory: ancient cultures cast artificial geopolymer stone—a tech lost & rediscovered multiple times. Egyptian pyramid blocks represent one late stage of this technology; megalithic stones from early periods may represent earlier versions. Pyramids were cast, not carved.
