broken vessels, &c.
36. FRENCH CHEMICAL SOAP
Take 5 lbs. castile soap, cut fine, 1 pint alcohol, 1 pint soft water, 2
ounces aquafortis (if for black cloth 1/2 ounce of lampblack,) 2 ounces
saltpetre, 3 ounces potash, 1 ounce camphor, 4 ounces cinnamon in
powder. Fist dissolve the soap, potash, and saltpetre by boiling, then
add all the other articles, and continue to stir until it cools, then pour it
into a box, let it stand 24 hours, and cut it into cakes. It is used for
taking grease, stains, and paints from cloth, wood, &c. This receipt has
frequently sold for $10.

37. BLACK INK WITHOUT SEDIMENT
This ink is not injured by frost--is a beautiful article, and only costs 5
cents. per gallon, and is sold for from $1 to $3. Take 1 lb. logwood, 1
gallon soft water, simmer in an iron vessel for one hour, then dissolve
in a little hot water 24 grains bychromate of potash, and 12 grains
prussiate of potash, and stir into the liquid while over the fire, then take
it off and strain it through fine cloth. This ink is a jet black flows freely
from the pen and will stand the test of oexylic acid.
38. INDELIBLE INK
1 inch of the stick of the nitrate of silver dissolved in a little water, and
stirred into each gallon of the above, makes first rate indelible ink for
cloth. Judge what indelible ink costs.
39. INDELIBLE INK
Nitrate of silver 1-1/2 oz., dissolved in liquor ammonia fortisine 5-1/2
oz., orchil for colouring 3/4 oz., gum mucilage 12 oz., mix the two
latter, then mix them with the two former, and it is ready to use.
40. WRITING FLUID OR BLACK COPYING INK
Take two gallons of rain water and put into it gum arabic 1/4 lb., brown
sugar 1/4 lb., clean copperas 1/4 lb., powdered nut galls 3/4 lb., mix
and shake occasionally for ten days and strain. If needed sooner, let it
stand in an iron kettle until the strength is obtained. This ink can be
depended on for deeds or records, which you may want someone to
read hundreds of years to come. Oexylic acid 1/4 oz., was formerly put
in, but as it destroys the steel pens, and does just as well without it--it is
now never used.
41. BEST INK POWDER
This is formed of the dry ingredients for ink, powdered and mixed.
Take powdered galls one pound, powdered green vitriol half a pound,
powdered gum 4 ounces, mix all together, put it up into 2 ounce
packages, each of which will make a pint if ink.
42. BEST RED INK
Take of best carmine (nakarot) 2 grains, rain water 1/2 ounce, water of
ammonia 20 drops, add a little gum arabic, and it is in a few minutes
ready for use.
43. YELLOW INK
Dissolve alum in saffron water to whatever shade of yellow you please.
It makes a beautiful ink.

44. BLUE INK
Take Prussian blue, and oexylic acid, in equal parts, powder finely, and
add soft water to bring it to a soft paste, and let it stand for a few days,
then add soft water to the desired shade of colour; add a little gum
arabic to prevent spreading.
45. GOLDEN INK
Take some white gum arabic, reduce it to an impalpable powder in a
brass mortar, dissolve it in strong brandy, and add a little common
water to render it more liquid, provide some gold in a shell, which must
be detached in order to reduce it to a powder, when this is done moisten
it with the gum solution, and stir the whole with a small hair brush, or
your finger, then leave it for a night that the gold may be better
dissolved. If the composition becomes dry during the night, dilute it
with more gum water in which a little saffron has been infused, but take
care that the gold solution be sufficiently liquid to flow freely in a pen;
when the writing is dry polish it with a dry tooth.
46. WHITE INK FOR WRITING ON BLACK PAPER
Having carefully washed some egg shells remove the internal skin and
grind them on a piece of porphyry, then put the powder in a small
vessel of pure water, and when it has settled at the bottom, draw off the
water and dry the powder in the sun. This powder must be preserved in
a bottle; when you want to use it put a small quantity of gum ammoniac
into distilled vinegar, and leave it to dissolve during the night, next
morning the solution will appear exceedingly white, and if you then
strain it through a piece of linen cloth, and add to it the powder of egg
shells in sufficient
