it's not a solid, and certainly not a liquid, and plasma is not really a state of matter...hmmmm....it's a gas!

The ancient Greeks and alchemists thought that fire was an element. They also considered earth, air, and water to be elements. However, the modern definition of an element defines it by the number of protons a pure substance possesses. Fire is made up of many different substances, so it is not an element.
For the most part, fire is a mixture of hot gases. Flames are the result of a chemical reaction, primarily between oxygen in air and a fuel, such as wood or propane. In addition to other products, the reaction produces carbon dioxide, steam, light, and heat. If the flame is hot enough, the gases are ionized and become yet another state of matter: plasma.

Fire or flame to be very precise is in state referred to by Physicists as PLASMA state of matter known as the fourth state of matter. This state is not fully understood but its many applications do exist. in fact 99% of Universe is in Plasma state.
Best example of Plasma state(apart from flames) is the Core of Sun or any other star where temp exceed 10,000,000 degree
some applications:
Plasma deposition and spraying (TPCVD, TPPVD)
-> Plasma welding and cutting
-> Thermal plasma decomposition : toxic gases, liquids, solid wastes
CVD(Chemical Vapor Deposition)
-> Plasma Polymerization
-> Surface Treatment
-> Sputtering
-> Plasma synthesis of ultra-fine powders : metal, advanced ceramic materials, nano-composites
-> Plasma densification (sintering)
-> Plasma metallurgy : melting, extractive metallurgy

Maybe a plasma, but i believe it's just hot gases and the flames themselves are actual more of an illusion. Rather than fire being a physical object it is actual just air that has heat energy that converts to light energy an radiates light on a spectrum from infrared(heat itself) to yellow (or ultraviolet depending on how hot it is). So fire isn't really matter, it's air so hot it radiates the illusion of flames.

The state of "fire" is gas.
