Dissolve twenty weight of white potash in three pailsful of water. Heat
twenty pounds of strained grease, then mix it with the dissolved potash,
and boil them together till the whole becomes a thick jelly, which is
ascertained by taking a little of it out to get cold. Take it from the
fire, stir in cold water till it grows thin, then put to each pailful of
soap a pint of blown salt--stir it in well. The succeeding day, separate
it from the lye, and heat it over a slow fire. Let it boil a quarter of
an hour, then take it from the fire. If you wish to have it a yellow
color, put in a little palm oil, and turn it out into wooden vessels.
When cold, separate it again from the lye, and cut, it in bars--let them
remain in the sun several days to dry.
