A Process for the Manufacture of Oil Colours.
I, ALEKSANDER TURSKI, of 24, Ogrodowa, Warsaw, Poland, in the Empire of
Russia, Chemist and Manufacturer of Oil Colours, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement: -
This invention relates to a process for the manufacture of oil colours which
are absolutely matte, that is to say entirely without lustre, and which are
adapted to be employed in the arts and industries. In particular these colours
are especially adapted for colouring walls and papers intended for wall hangings.
The process consists essentially in adding to ordinary oil colours a mixture of
powdered kaolin and purified oil of turpentine.
One of the principal reasons for employing water and size colours, which have
hitherto been almost exclusively used (although such colours possess no great
degree of durability and are readily effaced) is the absolute impossibility of
obtaining with ordinary lustrous oil colours a picture, or even a simple design,
either upon a ceiling or upon a wall which produces a good effect from all points
of view Nevertheless the employment of oil colours for such purposes is in the
highest degree desirable owing to their durable qualities and the facilities which
they offer for the cleaning of walls by means of water. The use of such colours
is rendered possible by means of this invention.
The quantity of the mixture which should be added to the ordinary oil
colour consists, according to the quality of this latter, of a mixture of from 20
to 40% of kaolin in a state of powder with 20 to 30% of purified oil of turpentine.
This mixture should be carefully triturated in a mortar, melting pot or other
appliance adapted for this purpose and after it has been added to the colouring
matter an oil colour is obtained which may be kept ready for use for as great a
length of time as desired; when this colour is applied to a surface it will appear
perfectly matte and without lustre of any kind.
Matte oil colours of this kind may be prepared in any desired shade, thus
not only advantageously replacing water colours for frescoes and for mural paint-
ings, but also affording the possibility of producing the most varied effects with
ordinary oil paintings.
In addition to this, these improved colours possess the advantage, still further
distinguishing them from ordinary oil colours, of being adapted for use in the
manufacture of oil-coloured wall papers and the like such as are in use at the
present time. For this purpose it is only necessary to coat a piece of fabric
having a smooth surface with oil colours prepared in the manner above indicated
without its being necessary to prepare or dress the said fabric in any way.
the same manner, ordinary paper may be employed in the manufacture of these
stained papers instead of a fabric such as calico or cotton.
In
Stained papers of this kind may be stuck upon walls in the well known manner
by means of ordinary paste. If it were desired to employ ordinary oil colours
for such a purpose, it is obvious that the fabric or the like would have to be
submitted to a suitable preparatory treatment.

page_text: This preparation usually consists in coating the fabric or paper with a thick
layer of size which renders it exceedingly stiff so much so that it becomes
impossible to make it adhere to the walls.
Papers and walls coloured by means of my novel matte oil colours are very
durable and may be cleaned as frequently as désired.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
A process for the manufacture of matte oil colours adapted for employment in
the arts and industries, such process being characterised by the addition to oil
colours of the ordinary kind of a mixture of kaolin and purified oil of turpentine.
