[QUOTE="Yaarel, post: 9318274, member: 58172"] The algorhithms of internet search engines today are bad, because they rely on "trends" rather than on established sites of information. The engines are almost useless for any serious searches, such as academic details. With regard to how medieval alchemists interpreted the helenistic elements, and applied them for metallurgy and astronomy, Rambam ("Maimonides") is knowledgeable. During the late 1100s, Rambam mentions the four states of matter in his work in Hebrew, [I]Mishna Tora[/I] (Hilkhot Ysode Ha Tora 3). He clarifies that these arent four different elements, but rather four different "forms" that any "clump" of elements might take. In other words, these are four states of matter − solid, liquid, gas, and plasma − not elements per se. He also describes the vacuum of outer space as being void of matter but pervaded by gravity, the farthest "orbiting" that is an immaterial "force". This fifth element, quintessence, is made out of "force" and is unlike the four states of matter. In his [I]Guide for the Perplexed[/I], he mentions a kind of "fire" called "darkness" that is between the earth and the moon, where this dark fire describes the plasmasphere of invisible nonluminous nonthermal plasma. It would take me some time to track down the phrase, "fire that burns fire". It is one of the ways to distinguish the alchemical "fire" from the ordinary fire of a candle. The alchemical fire refers to the state of matter that prevails in the "heavens", beyond the earth. If I recall correctly, it derives from a biblical verse, where Elijah calls down fire from the heavens. This "fire from God" was able to eat the entire altar, including the burning offering itself that is rising up in fire, along with eating the wood and even the stones and the dust. The alchemists understood this verse to mean, this heavenly fire is a state of matter that is able to destroy any form of matter. It is unlike ordinary fire. The heavenly fire can burn fire. These alchemist are doing real things, like figuring out how to make good steel for weapons.
