>     How to make lye: http://www.wikihow.com/Make-Lye 

    I'm confused - I know I come from a different part of the planet but
    I'm sure we have roughly the same chemicals...... 

    I always believed that Lye was an archaic term for an alkali but
    particularly POTASSIUM Hydroxide (Caustic Potash) - made from wood
    ash, but a number of people here have been referring to Lye as
    SODIUM Hydroxide or Caustic Soda - another chemical
    entirely............Which is correct? 

    Over here in the UK we have pretty much abandoned the slang names
    for chemicals and not before time. With sometimes up to half a dozen
    variations in name for one chemical (like Antimony Black and
    Antimony Glance for Antimony Trisulphide [or Trisulfide..]) and
    similar names for different chemicals (such as Copperas for Ferrous
    Sulphate and Blue Copperas for Copper Sulphate) these can be
    confusing. 

    As a good proportion of list members are now from countries across
    the world and the 'slang' or 'trade' names of the chemicals being
    described are not always consistent across different countries, it
    would be most useful if members would try to limit themselves to
    using the standard international chemical name of substances they are
    referring to.
