message: In "The Wars of the Roses" by Desmond Seward, , p.66, it mentions the use of what appears to be Greek Fire (in this case, referred to as 'Wildfire') during the Yorkist siege of the Tower of London in 1460.  The passage is as follows:
:"For the first time in history, the Tower turned its guns on London.  'They that were in the Tower cast wildfire into the City, and shot in small guns, and burned and hurt men and women and children in the streets,' a chronicler records.  'Wildfire' was the period's napalm, clinging to its target and burning more fiercely if water was thrown on it.  Understandably, most Londoners were only too eager to help Lord Salisbury with the siege."
Can anyone confirm if, for instance, the use of Greek Fire spread after the fall of Constantinople, or if this is a similar substance of a different composition, or if Seward is merely misinterpreting the reference to 'Wildfire'?

message: The speculation of whether Greek Fire contained a "secret ingredient" of either sodium, phosphorus or magnesium leaves one wondering. Scientifically, the base chemical compound (liquid) would have to be homogenous to flow smoothly through the delivery system to the nozzle.
Magnesium has a melting point of 992°K = 648.85°F or 1199°C. This would require a closed vessel at high temperatures and equally high pressures. Since Bitumen boils at approximately 350°F the likelihood of an explosion in a closed vessel due to a high-pressure increase would preclude this. 
Sodium has a melting point of 371°K = 208.13°F	or 97.85°C and Phosphorus a melting point of 
317°K =	110.93°F or 43.85°C. The likelihood of either of these elements being the one that would not go out when subjected to water is more likely.
Sodium/water chemical reaction:  2 Na + 2 H2O > 2 NaOH + H2 producing a bright red flame
Phosphorus/Damp Air at room temperature reaction: P4(s) + 5O2(g)  P4O10(s)
Reaction of Phosphorus Pentoxide in water leaves an acidic residue following a highly exothermic reaction and water vapor.
P4O10 --+2H2O--->H4P4O12---+2H2O--->2 H4P2O7---+2H20--->4 H3PO4
Phosphorus Pentoxide is used as a dehydrator due to the water evaporating property.
Given that the low boiling point of the Sodium and the red flame, it is more highly probable that sodium was the additive.
Red Flame?  I am sure you know Sodium produces an orange flame, with strong yellow coloration.
Calcium though, makes a red flame.  Jokem 02:22, 17 May 2007 (UTC)

message: This was removed from the article because magnesium was supposedly unknown to the Byzantines: 
:"One other incendiary substance, perhaps that secret ingredient may have been magnesium, which will burn under water, and is a principal constituent in incendiary bombs of modern warfare."
Our magnesium article says pure magnesium is produced using electrolysis, but surely some form of magnesium was known in the middle ages. Does it not come from Magnesia, which is an extremely ancient site? Adam Bishop 18:19, 20 Jan 2005 (UTC)
replies: text: There is a big difference between pure magnesium and some form of magneisum. From the magnesium article: "It is an alkaline earth metal and therefore does not occur uncombined with other elements." The more reactive an element is, the less likely you are to find it pure in nature. Conversely, the natural compounds that such an element can be found in are often the most stable, because the reaction energy released when the element bonds has to basically be reversed in order to break that stable bond (sodium and chlorine, for example). So, magneisum oxide, magnesium chloride, or other natural magnesium bearing minerals and compounds, are not very reactive. Anywho, it is highly unlikely that there was a known process for isolating pure magneisum at that time. Even now, it is not easy to process, and yet it is so common we get most of it from sea water via electrolysis.... Of course, we used to think that the secret to melting and working platinum was unknown to man prior to the oxygen fed flame, except certain South American Indian tribes had been doing it for possibly thousands of years. So, anything is possible. Splarka 03:55, 2 August 2005 (UTC)

message: Watching the movie Timeline was the first time I've heard of Greek Fire up until now.  Based on what is written here about the creation, means of communication, and effects, I think the movie did a very good job depicting what Greek Fire might actually have looked like.  The movie's pretty brainy for trying to be a Richard Donner film, which is why it flopped, but on the whole, it does a great job of explaining the nature of Greek Fire without a whole lot of expo.  I'm going to read the book by Michael Crichton soon, and I'll update my entry with the details it gives me.  Please don't edit out my entry again, Mr. Knowsbest.  The nature of this encyclopedia is not to weed out what is and is not relevant, but to compile knowledge about things, both important and trivial.  Perhaps some student might use the clips from the movie for a report on Greek Fire in school.  
P.S. I also added to the Timeline(movie) page about Greek Fire, to complete the circle.

ingredient of the mixture was almost certainly crude oil from natural surface wells on the

replies: text: The article makes clear that the "original" Greek fire, i.e. the formula designed to be launched pressurized via siphons, was no longer in use already by 1200. Its secrets would most likely have been lost either way after the sack of 1204. The stuff used in the fire-ships in 1453, as well as the (IIRC) "Greek fire" used in combating Ottoman sappers, were probably some other incendiary mixture, perhaps even saltpetre-based. It is impossible to know, but odds are against it being the same substance as used in the Arab sieges. Of course, this assumes that there was only one "original" Greek fire, and not a variety of petroleum-based formulas already in use at that time (V. Christides for instance certainly thinks so), but most scholars differentiate between the siphon-launched substance and any other. Constantine   ✍  12:37, 29 November 2010 (UTC)

Biodiesel has all the qualities typically attributed to Greek Fire, (being liquid, highly flammable, floats on water, burns on water, can be pumped and sprayed, it is explosive, and by adding quicklime it becomes flammable when put in contact with water). It is likely that this possibility was largely overlooked by scholars even now and still is nowhere to be found on this page as a candidate. The reason no one has though about the possibility have not every considered it a candidate for Greek Fire is because we only recently rediscovered the technology out of necessity ourselves.  — Preceding unsigned comment added by 24.178.26.82 (talk) 14:23, 13 February 2016 (UTC)

message: I see that the "Frank Leslie's Illustr. Newspaper" uses the term "Greek fire" in Jan. 30, 1864, in relation to the American Civil War (page 2, 1st column, "Summary of the Week"). Obviously it means some kind of incendiary bomb.--Skylax30 (talk) 13:22, 12 October 2016 (UTC)

message: I get tired of the claim that "most scholars" say/believe this or that. Did someone actually send most scholars a POLL to ask them? Without such substantiation, this claim to fact needs to be eradicated from every article and book ever written. Misty MH (talk) 18:30, 29 August 2018 (UTC)

message: One of the two undetermined components for the Italian Recipe at the bottom of the Theories of Composition, "Pegola" is most likely pitch. The word "pegola" doesn't seem to have any modern uses, but it appears in a 1650 English to Italian Dictionary as the word for pitch. And given that pitch makes sense as a potential ingredient in greek fire and was available at the time, I'm confident that's the right translation.

message: "it includes coal from a willow tree, alcohol, incense, sulfur, wool and camphor as well as two undetermined components (burning salt and pegola); the concoction was guaranteed to "burn under water" and to be "beautiful."
This sentence should be charcoal rather than coal surely? 
You can only get willow coal from rocks off coal that for generated from JUST willow trees, which is almost impossible.
But I did not want to make a change without discussing it first. Eco-climber (talk) 07:58, 2 October 2020 (UTC)

message: Is it really irrefutably verified that Greek fire was around (at least in the form that would later be used) by 672? I'm aware that there are doubts about this, or that that first Arab siege of Constantinople even really happened in the way that is popularly imagined. Is it possible that it was more likely just fire ships used in that one, and that actual Greek fire didn't surface in usage against enemies until the larger 717 episode?

message: The description of Greek Fire and calcium phosphide is cited for The New Penguin Atlas of Medieval History by McEvedy. I went through the work of borrowing this book (1992) from the Internet Archive precisely because I wanted to read more about this (and the claim that calcium phosphide can be made by boiling bones in urine in a closed vessel). However, "Greek Fire" appears only once in the entire book, and the words "urine" and "calcium" don't appear at all. CSJordan (talk) 03:52, 28 December 2022 (UTC)
