AN INK RESTORER.

The process consists in moistening the paper with water and then passing
over the lines in writing a brush which has been wet in a solution of
sulphide of ammonia. The writing will immediately appear quite dark in
color, and this color, in the case of parchment, it will preserve.

COLORS FOR HOLDING BRONZE.

Red and green inks are good colors for holding bronze, when you are not
working with size or varnish.

STENCIL INK.

A good and cheap stencil ink in cakes is said to be obtained by mixing
lampblack with fine clay, a little gum arabic or dextrine, and enough
water to bring the whole to a satisfactory consistence.

COPYING INK TO BE USED WITHOUT PRESS OR WATER.

Well mix three pints of jet-black writing ink and one pint of glycerine.
This, if used on glazed paper, will not dry for hours, and will yield one
or two fair, neat, dry copies, by simple pressure of the hand, in any good
letter copy-book. The writing should not be excessively fine, nor the
strokes uneven or heavy. To prevent "setting off," the leaves after
copying should be removed by blotting-paper. The copies and the originals
are neater than where water is used.

WHITE INK.

There is really no such article as "white ink." A true ink is a solution
of some substance or combination of substances in liquid. Colored liquids,
however, may be prepared with various substances not soluble in the
liquids available for writing fluids. A "white ink" may be made by rubbing
the finest zinc white, or white lead, with a dilute solution of gum
arabic. It must be stirred up whenever the pen or brush is dipped into it.

PURPLE HEKTOGRAPH INK.

To make the purple hektograph ink:--Dissolve 1 part of methyl-violet in 8
parts of water, and add 1 part of glycerine. Gently warm the whole for
about an hour, then allow to cool and add 1/4 part alcohol. It is said, on
good authority, that the alcohol may be advantageously omitted, and that
the following proportions will give even better results than the above,
viz: Methyl-violet, 1 part; water, 7 parts; glycerine, 2 parts. This
formula, it is said, produces an ink which is less liable to sink into the
paper.

A DARK RED INDELIBLE INK.

An indelible red ink for marking linen may be made from the following
formula:

Prepare three separate solutions:

I. Sodium carbonate 3 drs.
Acacia 3 "
Water 12 "

With this moisten the spo
