“There is no way of distinguishing a synthetic zeolite from a natural one.”

“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 {{w|zeolite}}s, secondary rock-forming minerals.”

“I am a research scientist specializing in low-temperature mineral synthesis. In 1972 I founded the private research company CORDI (Coordination and Development of Innovation), and, in 1979, the Geopolymer Institute, both in France. At the Geopolymer Institute a new branch of chemistry that I named {{w|geopolymer}}ization. I currently have more than twenty-five international patents for geopolymeric products and processes. My products are made... by large manufacturers. The products have many diverse applications.”

“[T]he pyramid blocks are not natural stone; the blocks are actually exceptionally high-quality {{w|limestone}} concrete—synthetic stone—cast directly in place. The blocks consist of... ninety to ninety-five percent limestone rubble and five to ten percent cement. ...imitations of natural limestone, made in the age-old tradition of alchemical stonemaking. No stone cutting or heavy hauling was ever required...”

“[T]he priests of {{w|Khnum}} had long been adept at the art of making extraordinary cements. Cement found in... the Great Pyramid... is still in good condition. This ancient mortar is far superior to cements used in construction today. The modern {{w|portland cement}} used to repair ancient Egyptian monuments has cracked and degraded...”

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

“All available stones... possessed sacred, eternal qualities. ...[A]ll living things perish ...the imposing rocks and cliffs stood eternally. ...[S]tone was symbolic of the eternal realm. ...[S]tone materials were devoted exclusively to religious monuments and sacred funerary paraphernalia. ...intended to survive for eternity.”

“The ancient Egyptians are well known for using minerals such as chrysocolla and {{w|lapis lazuli}} to produce enamels... They had a word for such products, ari-kat, meaning man-made or synthetic. ...[T]he highest spiritual influence was attributed to stone. ...{{w|carnelian}} and other red stones represented the blood of {{w|Isis}} ...Lapis lazuli was associated with daybreak. Chrysocolla was associated with ...the "First Time" event of Creation. ...[M]inerals and rocks had divine properties in a world where all of nature was revered.”

“Egyptian alchemists developed vibrant blue enamel... a by-product of copper {{w|smelting}}. ...[A]n experimenter mixed a powder of {{w|chrysocolla}} with {{w|natron}} and applied a flame. The... hard, glossy blue enamel... was ...applied to beads and pebbles.”

“Temperatures can be raised with energy released during exothermic... reactions. Copper and {{w|lead}} are commonly located in close proximity... A mixture of ...{{w|malechite}} ...and ...{{w|galena}} ...heated to only to 700 °C ...automatically reaches a temperature, through a heat producing chemical reaction, that is close to that for extracting copper. The addition of a flux, which in Egypt was a native salt called {{w|natron}} ({{w|sodium carbonate}}), lowered the fusion point sufficiently for copper extraction. Silver can be smelted similarly.”

“The science that made the pyramids possible was chemistry, or, more precisely... alchemy. ...[T]he legendary Philosopher's Stone represents the last misinterpreted vestiges of the alchemical science that flourished during the Pyramid Age ...Technically alchemy encompasses historical chemical developments. ...There were great alchemical achievements during antiquity.”
