Hi Earthling,
The Australian Methylated Spirits is one of the best quality alcohol fuels available anywhere in the world, it contains 95% ethanol, the rest being mainly water with some Methanol and other additives to make it undrinkable.
If you want to know more about
alcohol fuels and
alcohol water mixtures but you have to join or pay
BPL to read them.
The reason Tinny gets a nice blue flame on the Mushroom is that he uses Methanol which burns with a blue flame, but Methanol is not as efficient as our metho which burns with a more yellow flame, personally I would not bother but as Franco suggested adding a small amount of water to Metho will not harm the efficiency and will make the flame look more blue, adding water will also slow down the boil times, please note that slow boil times does not mean less efficiency or more fuel used. (fast boil time equals a more efficient stove is a myth that some stove manufactures push to try and sell more stoves).
