What else could be the Greek fire? Many scholars of antiquity, trying to uncover the mystery, made all sorts of chemical mixtures, which included almost all known at the time incendiary.
The first attempt to lift the veil of secrecy was made by the Byzantine historian of the Princess Anna Comnenus (1083-1148). In her recipe featured only three components: resin, sulfur and tree sap..
In France, some Dupre devoted to disclosure of this secret his whole life. Finally, completing the quest, he sold his discovery to the French king Louis XV (1710 – 1774). During testing, the king was horrified, and, as legend has it, ordered to destroy all documents that show the opening Dupre. Soon, the inventor himself died under mysterious circumstances …
In the middle of the XIX century French historian and archaeologist L. Lalanne, Orientalist Joseph Renaud and Professor FAWE, trying to find the key to the age-old mystery, made the study of Arabic, Greek and Chinese sources. In their view, the composition of Greek fire came close to the Chinese incendiary substances, known long before our era, containing a large quantity of nitrate.
German specialist A. Shtetbaher in the book “Powders and explosives” (1937) believes that Greek fire was composed of sulfur, salt, tar, asphalt and burnt lime. Composition, in contact with water, heated, with the heat of slaked lime evaporated portion of combustible material, which in combination with the air gave legkovzry-contracting mixture.
More recently, in 1960 in Cambridge came Dzh.Partinggona capital study “History of Greek Fire and gunpowder.” English scientist came to the conclusion that Greek fire was a jelly-like fluid, consisting of lighter fractions of petroleum refining, resins and sulfur.
Partington believes that Greek fire could not be a substance resembling gunpowder, and therefore in its composition could not be nitrate, as it believed the French researchers.
We agree with the fact that Greek fire can not be equated with the black powder at the same time, one can not argue against the fact that Greek fire could not include nitrate.
She could play the role of a thickener or be an oxidizing agent, increasing the power of fire. Perhaps the Greek fire is made up of the product light fraction of crude oil distillation, various resins, oils, and possibly nitrate or quicklime.
It is not for nothing that the Byzantine, Arab and Latin sources indicate that the Greek extinguish the fire can only be … vinegar.
However, this and all other assumptions – only conjecture, with no results so far no confirmation.
