_Prep._ 1. Aleppo galls (well bruised), 4 oz.; clean soft water, 1 quart;
macerate in a clean corked bottle for 10 days or a fortnight, or even
longer, with frequent agitation, then add of gum Arabic (dissolved in a
wine-glassful of water), 1-1/4 oz.; lump sugar, 1/2 oz.; mix well, and
afterwards further add of sulphate of iron (green copperas, crushed
small), 1-1/2 oz.; agitate occasionally for 2 or 3 days, when the ink may
be decanted for use, but is better if the whole is left to digest together
for 2 or 3 weeks. When time is an object, the whole of the ingredients may
at once be put into a bottle, and the latter agitated daily until the ink
is made; and boiling water instead of cold water may be employed.
_Product._ 1 quart of excellent ink, writing pale at first, but soon
turning intensely black.
2. Aleppo galls (bruised), 12 lbs.; soft water, 6 galls.; boil in a copper
vessel for 1 hour, adding more water to make up for the portion lost by
evaporation; strain, and again boil the galls with water, 4 galls.; for
1/2 an hour; strain off the liquor, and boil a third time with water,
2-1/2 galls., and strain; mix the several liquors, and while still hot,
add of green copperas (coarsely powdered), 4-1/2 lbs.; gum arabic (bruised
small), 4 lbs.; agitate until dissolved, and after defecation strain
through a hair sieve, and keep it in a bunged-up cask for use. _Product._
12 galls.; very fine and durable.
3. Aleppo galls (bruised), 14 lbs.; gum, 5 lbs; put them in a small cask,
and add of boiling soft water, 15 galls.; allow the whole to macerate,
with frequent agitation, for a fortnight, then further add of green
copperas, 5 lbs., (dissolved in) water, 7 pints; again mix well, and
agitate the whole once daily for 2 or 3 weeks. _Prod._ Fully 15 galls.
Resembles No. 1.
4. Galls (bruised), 9 lbs.; logwood chips (best Campeachy), 3 lbs.; boil
as in No. 2; to the strained mixed liquors, add of gum arabic and green
copperas, of each (bruised small), 4 lbs.; simmer or digest until
dissolved, and at once strain through a hair sieve into the store-cask or
jars. _Prod._ 16-1/2 galls. Excellent, but inferior to the preceding.
5. Galls (bruised), 2 lbs.; logwood chips, green copperas, and gum, of
each 1 lb.; water, 7 galls.; boil 2 hours, and strain. _Prod._ 5 galls. A
