687. Mix in six drachms of distilled water, two drachms of
sub-nitrate of silver, and two drachms of gum-arabic. For the
mordant, mix with four ounces of water, half an ounce of gum-arabic,
and half an ounce of sub-carbonate of soda. The article to be marked
should first be wetted with the mordant, and pressed smooth, and
should be thoroughly dried before it is written upon. The mark should
be exposed to the light for some time, to become black.
688. _Permanent Red Ink for marking Linen._--This useful preparation,
which was contrived by Dr. Smellie, of Edinburgh, who was originally
a printer in that city, may be used either with types, a hair pencil,
or even with a pen: Take half an ounce of vermillion, and a drachm of
salt of steel; let them be finely levigated with linseed oil, to the
thickness or limpidity required for the occasion. This has not only
a very good appearance, but will, it is said, be found perfectly to
resist the effects of acids, as well as of all alkaline leys. It may
be made of other colors, by substituting the proper articles instead
of vermillion.
689. _An Indelible Ink for marking Linen._--Pour a little aqua-fortis
into a cup, and add to it a small piece of pure silver; when the
effervescence ceases, filter the solution through a piece of
blotting-paper, and put it into a small phial; then add to it a
little gum-arabic and a little of the paint, called sap-green. After
the whole is perfectly combined it is then fit for use.
690. _To take out Writing._--When recently written, ink may be
completely removed by the oxymuriatic acid (concentrated and in
solution). The paper is to be washed over repeatedly with the acid;
but it will be necessary afterwards to wash it also with lime-water,
for the purpose of neutralizing any acid that may be left on the
paper, and which would considerably weaken it. But if the ink have
been _long_ written, it will have undergone such a change as to
prevent the preceding process from taking effect. It ought therefore
to be washed with liver of sulphur (sulphuret of ammonia), before the
oxymuriatic acid is applied. It may be washed with a hair pencil.
691. _To make Old Writing legible._--Take six bruised gall-nuts, and
put them to a pint of strong white wine; let it stand in the sun for
forty-eight hours. Dip a brush in it and wash the writing, and by the
color you will discover whether the mixture is strong enough of the
galls.
