Suet is the basis of all the soaps of the toilette, known by the
name of Windsor soap, because olive-oil forms a paste too difficult
to melt again, and contains an odour too strong to be mixed with
essences. The suet soap dissolved hot in alcohol retakes its solid
state by cooling. To this fact is due the discovery of transparent
soap, which, if well prepared, has the appearance of candied sugar;
it may also be coloured, and the vegetable hues for this purpose, are
preferable to mineral; any person may make this soap, by putting in a
thin glass phial, the half of a cake of Windsor soap-shavings; fill
it with one half of alcohol, and put it near the fire until the soap
is dissolved; this mixture, placed into a mould to cool, produces the
transparent soap.
