INTRODUCTION
M an y s a y th at p e n is mi gh ti e r t ha n
s wor d, b u t e ver thought that what makes
the pen mightier? Yes it is the wonder liquid
INK. You might have used ink many times for
writing but have you ever bothered that
from where it comes? How it is prepared?
Th is p r o jec t i nc l u de s an s w e r o f al l
you r questions. T h i s p r o j e c t t h r o w s a
light on types of inks from
manufacturing point of view and includes
method for preparing them either in chemistry
laboratory or at home.
HISTORY OF INK
The history of Chinese inks can be traced back to
the 12th century BC, with the utilization of natural
plant (plant dyes), animal (squid ink), and mineral
offset ink based on such materials as graphite that
were ground with water and applied with ink
brushes. Evidence for the earliest Chinese inks,
similar to modern ink sticks, is around 256 BC in
the end of the Warring States Period and produced
using manual labour from soot and animal glue.
About 1,600 years ago, a popular ink recipe was
created. The recipe was used for centuries. Iron
salts, such as ferrous sulfate (made by treating iron
with sulfuric acid), were mixed with tannin from
gallnuts (they grow on trees) and a thickener. When
first put to paper, this ink is bluish-black. Over time
it fades to a dull brown.
Aniline Ink
MAIN MATERIALS REQUIRED
Blue-black color - Naphtha blue-black
Blue color - Acid blue, Methylene blue
Red color - Scarlet red, Eosin
Black color - Aniline black
Green color - Malachite green
Some aniline colors are also used in preparing
ink which is dissolved directly in water.
PREPARATION OF ANILINE INK
For preparing a particular colored ink, first of all a 2.5%
solution of that color in distilled water is made.
To this, is added a suitable amount of glue solution.
Now the solution is mixed well and heated for 5
minutes.
During heating, the contents are constantly agitated.
On cooling, the solution is filtered. The process of
filtration is a very important step and is carefully
repeated several times.
To this is now, mixed a little amount, each of boric acid
or carbolic acid, alcohol or spirit and scented material.
This preparation is filtered again and bottled.
If one desires to get a stamp-pad ink then glycerine
should be used in place of alcohol during preparation
Gallo-Tannic Ink
MAIN MATERIALS REQUIRED
Tannic and Gallic acids are used as chief constituents to get blue-
black ink.
Ferrous sulphate and hydrochloric acid also helps in providing blue-
black color to the ink and check the growth of fungus.
Other materials: The other materials used are carbolic acid or boric
acid, gum Arabic or gum acacia, spirit or alcohol, glycerine and
scented material etc. These substances play the same role in this
case as in aniline ink. Basically, it is a mixture of ferrous sulphate ,
tannic acid and Gallic acid; it is, therefore, also called Iron-gall ink.
Method Of Preparation Of Gallo-
Tannic Ink
Dissolve 250 gm of tannic acid and 80 gm of Gallic acid
in about 5 liters of distilled water.
To this solution 250 ml dilute HCl is added.
Dissolve in a separate container 300 gm ferrous
sulphate, 20 gm carbolic acid about 4 liters of water.
In a third container, the desired color is dissolved in a
little water.
All the three solutions are mixed together.
Also add a little of glue solution, alcohol, scented
material, mix well, filter and keep the filtrate for a few
days.
Filter once again and store in bottles. The ink is ready
for use.
How To Prepare Ink At Home
One drop at a time, add hot distilled water to the bowl of
lampblack (you can make your own by completely burning
paper or wood) - stop adding water before you think you
should and if you, accidentally, get too much water, add
more lampblack. Mix until the water is an inky black
(lampblack floats and is difficult to dissolve). Once the water
is inky black, add a small amount of gum Arabic and mix
until the gum has been dissolved in the warm liquid (this
homemade ink should be the same consistency as
commercially prepared ink). Store the ink in a small glass
bottle for future use. A variant of this recipe is: mix together
one egg yolk, one tablespoon gum Arabic and 1/2 cup
honey; then stir in 1/2 tablespoon lampblack: this will
produce a thick paste which you can store in a sealed
container. To use the ink, mix this paste with a small
amount of water to achieve the desired consistency.
