At first the available colors are ground on a
stone slab (by rubbing or grounding) to bring them in a powder
form. Some artists use mortar and pestle of a very hard quality
stone. Then that color is dissolved in water along with some gum
and then filtered. The filtration process is continued till the
color becomes totally earth or sand free. Thereafter water is
removed and the color is dried and kept in form of balls. When
required, the desired color along with some dry gum is dissolved
slowly in water with the help of finger or thumb. The color is
By dissolution, the color starts getting thicker
and gains the consistency of a paste and then pressure is required
to be applied. The color gets well mixed from the strength applied
at this time. This process is termed as tempering. Thus this process
is termed as Tempera. If the color is once allowed to get dry
and then made thinner as per requirement by adding water then
it gives better results.
The colors used in painting can be divided into
four main groups:
Colors available in the form of stones come under
this category. For example consider the color black . Black is
a basic color. A sand lamp is placed over a lighted lamp till
black soot or lamp black "kajal' is obtained therefrom. Babul
gum, Acacia resin and water are added to this kajal and ground
slowly with the first finger till it gets tempered to obtain a
fine black color. Black ink is also prepared at Jaipur in this
manner. The only difference in the writing ink and black color
is that the former has more gum than the latter. color prepared
from the soot of a lamp using mustard oil, though being a watercolor,
is unassailable by water after it has dried on the paper.
The colors obtained from different parts of trees
or plants come under this category. For example the preparation
of Red color from the bark of the peepal tree. The bark is immersed
in water and cleaned. Then it is crushed along with borax -suhaga
and heated in an iron pot. This makes the color come out. This
color can be preserved in cotton wool or it can be kept secure
by concentrating in tablet form.
are obtained by burning, pulverizing or mixing various materials
by chemical process. For example consider the emperor of all green
colors, the Jangal color. Copper powder one ser (One ser = 900
gms. approx.) and Nausadar (sal-ammoniae) two ser both should
be kept in a copper pot. Lime juice should be squeezed into it
till it is two fingers (about one inch) above the medicine(material
in the pot).
The mouth of the pot should now be covered by a cloth.
It should be kept forty days in that condition. The material should
then be ground in the same juice and then dried up in shade. Good
quality Jangal will result. Whenever required, it should be mixed
with glue to use. Gum doesn't suit this color.
The fine powder of gold, silver and lead have
been used in paintings as well as mica pieces. It can be ground
and applied like other colors. Gold leaves are used in two ways.
In the first process, the leaves are pasted directly. For this
a mixture of glue and sugar is applied at the required spot in
the required size. Thereafter the gold leaves are pasted, moistening
it with mouth vapours in between. Minute and fine work is done
by means of golden or silver powder specially prepared. It is
called Hilkari in local dialect. To prepare Hilkari, a thick paste
of gum, glue or honey is applied on a metal plate. The gold leaf
is pasted over it and it is rubbed with the help of four fingers
or the palm in a rotating manner.
By doing so, the leaves turn
into a fine powder. It is necessary that the paste on the plate
should be thick. If the paste is thin then the gold leaves would
turn into balls. This finely ground gold powder is transferred
to a tumbler gradually and simultaneously with water. In the end
the whole glass is filled with water and the Hilkari. It is left
as such for 24 hours and then the water is drained off. The gold
or silver settles at the bottom. When required, it may be applied
after mixing a small quantity of gum. On rubbing agate stone over
it, that part begins to shine like gold. With Hilkari the quantity
of gum should not be much otherwise the gold would not shine.
