    Many thanks!

    "Manteca" means "butter" in Spanish. My mistake here, as a native Spanish speaker.

Not 'power the house" electricity, but "make a small batch of chemicals" electricity.
    Batteries are OK. The point is that Customs bureaucracy has become a kind of PITA (not certain why PITA stands for "pain in the neck", though ;-) ). My guess is that importers (either of final products or materials for production) are focused in things with high added value. In our case (shaving soaps) Gillette and other major manufacturers are selling pressure cans with either foam or gel, for example, but not the traditional (and cheap) solid shaving soap bars, or semi-solid jars.

    4. Note that 2 and 3 make DIFFERENT forms of lye. I send you these links because if you can't get soap, it's highly unlikely you will be able to find Lye (Sodium Hydroxide NaOH) or Potassium Hydroxide.
    As stated above: I think I can; it is just that I am not sure if we are referring to the same NaOH...

You should go one step further and simmer (NOT BOIL) the lye until it is a dry powder. Then you can dissolve the correct amount. You can also check the pH for 'neutrality' or 'baseness' using litmus paper. You want your soap to have neutral pH. Hugely important, and hugely hugely important for soap used on children, the elderly, or beautiful ladies with radiant skin. Not so important for macho manly men that don't care about walking around with huge chemical burns on their dumb selves.
    I am a "macho" man, but not one of those ;-)

    I'll ask about the paper. There are widely spread pH meters for laboratories, swimming pools, and gardens. Might get one of those if useful.

    Thanks again.

    The great soap "Mitchell's Wool Fat" name comes to mind.
    Lanolin is a wax, not an oil. It is wool wax.
    "Lana" in Latin and in Italian means wool.
