When the Egyptian alchemists developed glassmaking during the New Kingdom, it was to carry on the old religious tradition of making synthetic stones. - Joseph Davidovits

[I]n the... early stage of polymer chemistry the question was raised on the ability of Si to generate chains... analogous to the s. ... (1912) isolated the compound SiH₄, the chemical structure ...equivalent of (CH₄). ...F. S. Kipping published his results on the preparation of the ... group (also called siloxo) Si-O-Si ...from the condensation of two groups and formation of water ...The ...reaction yielded ...organic mineral polymers known as s. ...Very soon after this ...it became evident that the silicone bridge -Si-O-Si- had something in common with the ...structure of (Almeningen et. al., 1963).

Geopolymeric products range from advanced materials to simple, yet highly sophisticated cements. The geopolymeric cements are made with inorganic chemical reactions in which alumina and silica materials are integrated to form synthetic s, secondary rock-forming minerals.

They turned back to mud because mud bricks is also a replica of incarnation, in the materials that belong to the Khnum divinity.
