    You rang, M'lord?  And G'day;    Methyl alcohol is also methanol and
    is very poisonous. They put it in 'methylated spirits' in NZ and
    England to stop people drinking it - but of course it doesn't; (hence
    the term 'metho's')  it merely sends them blind and mad. 

    Ethyl Alcohol is also ethanol.  This is often made by soaking grain
    (barley, wheat, corn etc) in water, allowing it to just sprout which
    produces sugars and enzymes, dissolving out the sugars and fermenting
    them with yeasts, then distilling off the ethanol which is of course
    a waste product of the yeast growing and multiplying.  Hence the term
    'grain spirit'.  Almost all countries in the world place a tax on
    grain spirit beverages including vodka, which is pure ethanol fairly
    heavily diluted with water. Generally a special license is required to
    buy ethanol; industrial grade 90-96% or 'absolute' 98%, and only
    laboratories and certain industries can obtain such a license; a
    privilege  which is jealously guarded. (ordinary folk like you, me,
    and the bootleggers have to make their own cheap untaxed ethanol.)  In
    Australia the Colonial Sugar Refining Company make vast quantities of
    the stuff, some in the form of rum.  Ethanol is also make from
    natural mineral oil by speciality petroleum product refiners.  Don't
    forget that ethanol is also poisonous (toxic) - hence 'drying out' is
    called detoxification. Methanol is also made from petroleum products -
    in vast amounts as it is used as a starting material for a large
    number of chemicals. Like I said, it is exceedingly poisonous.   It
    can also be produced in certain fermentation reactions. 'Bath tub
    gin'? 

    Then there are n.propyl, iso-propyl, (propanols) iso and n. and
    tertiary butyl (butanols) alcohols; (And others) all of which are used
    commercially in various but large amounts.  Most of which are
    poisonous in varying degrees and amounts. 

    There are a very large number of other alcohols, produced naturally
    by certain plants, but we won't bother with those either.  

    So, what should one use in a spirit lamp? I suggest one of the
    commercially available  alcohols sold in paint stores and hardware
    shops. Just don't breathe the vapours and don't drink the stuff. I
    have used spirit lamps containing 'methylated spirit' most of my life
     and have drunk alcohols since I was 20 (I prefer rum, with lemon or
    cloves please, depending on the ambient temperature) So there you are,
    more than you ever wanted to know about alcohols - you can blame Skip
    Meister for all this.  Cheers.
