The best kind is clarified by merely melting it in a water bath,
and taking off the scum; the middling kind by dissolving it in
water, adding the white of an egg to each pint of the solution; and
boiling it down to its original consistence, skimming it from time
to time. The inferior kind requires solution in water, boiling the
solution with one pound of charcoal, to 25 pounds of honey, adding,
when an excess of acid is apprehended, a small quantity of chalk
or oyster-shell powder; next by straining it several times through
flannel, and reducing the solution to its original consistence by
evaporation.
