Interestingly, there was a lot of arson going on in the early 1900s but the angle I wanted to pursue was the accelerant. Turns out that is the wrong term to use for what makes the fire burn..
From Wikipedia: Some fire investigators mistakenly use the term “accelerant” to mean any substance that initiates and promotes a fire without differentiating between an accelerant and a fuel. The terms are not, in the truest sense of chemical science, interchangeable. To a chemical engineer, “gasoline” is not at all considered an “accelerant”, it is more accurately considered a “fuel”, but usage by laymen is considered popularized if incorrect.
Ok, understood, changing that immediately!
