Liquid Castile Soap: Olive Oil Boiled with Caustic Potash

Potash makes a soft soap where soda makes a hard one, and soft soap dissolves easily, so an olive-oil potash soap thinned with water is liquid castile soap. The boiling follows the soft-soap practice Andrew Ure described in 1839: oil and caustic potash lye added by turns and boiled gently until the paste turns clear. The picture: Norwegian green soap (grønnsåpe), another soft soap of fat and potash lye.

Arahan

1

Make two lyes

Dissolve caustic potash in water to make a weak lye (hydrometer 1.05) and a strong one (1.20). Add the potash to the water, not the water to the potash.

Keep it at the gentlest boil, adding a little strong lye now and then. The froth settles, the paste turns clear and thickens.

Test on a glass plate

Cool a dab on a sheet of glass. It is done when it is clear, not milky, and a thin opaque ring forms round its edge (Ure: the soap has its "strength"). Then take it off the heat.

Limits

The boiling and the glass-plate test are Ure's; the quantities, the hot plate and the dilution are ours. Caustic potash lye burns skin and eyes.
