Tovarischi,
Fire bottles have more research and testing involved than many of us would realize.
There were many configurations used by various countries such as Britain, Germany, Finland, Soviet Union. All sorts of ignition systems were used including "storm matches" (sparklers), self igniting chemicals(sulfuric acid), metallic ignition systems, rags, etc.
I have been fortunate enough to run across many examples of the little jewels on various websites around the world and they are truly neat pieces of technology.
The Finns were the ones to truly develop it as a weapon with a method to the madness. The Soviets learned how to apply this same technology after losing approximately 350 tanks and other vehicles to such weapons during the Winter War.
After research and testing the Finns realized that the perfect bottle was the 1 liter vodka bottle which was produced in the state liquor factory. It utilized a screw cap which worked well.
Estimates are that in 115 days the Finnish factory cranked out approximately 542, 194 "Molotov Cocktails." Not bad.
Some of the mixtures listed as being utilized in the fire bottles included:
Petrol & Tar
Petrol, Kerosene & Tar
Potassium chlorate, Tar and Noulee
Benzene and gasoline
Flame Thrower fuel and gasoline
Waste Spirit and Kerosene
It appears that a lot of mass production was employed in making these lovely little fire makers.
However, necessity is the mother of invention and when there are no "commercially made" products available then it is time to improvise.
The 1941 "Partisans Companion" gives simple but effective instructions on how to craft one in the field using readily available materials.
The various components are as per listed in the following sources:

I have never been one to rely on conjecture when perfectly good information is already available. Research is full of rewards.
Hope this helps.
Sincerely,
Dima
