An Improved Preparation of Colouring Matters for Dyeing, Painting,
Drawing, and other Purposes.
We ERNEST NIENSTAEDT, Chemist, LEO GOLDMARK, Merchant, and CARL
HERRMANN, Merchant, all of No. 13 West 42nd Street, New York City, County
and State of New York U.S.A. do hereby declare the nature of this invention and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
This invention has reference to a new means for preparing coloring and dyeing
fluids, for dyeing, painting, drawing and other purposes and the invention consists
of a stick having on one or both ends a hardened coloring composition which can be
entirely or partly dissolved or suspended in a suitable solvent. These color sticks
are made in the following manner :--
Any required animal, mineral or vegetable color-stuff is intimately mixed with a
suitable binding material, as dextrine, sugar, gum arabic or the like, or dissolved
therein according to the nature of the color-stuff, so that a sticky and pasty mass is
obtained. Into this mass thin sticks of wood, glass, metal or any other suitable
material, of about the size of the common matches, are dipped, so that a certain
portion of the said pasty mass adheres on the same when they are removed there-
from. The adhering portions of the coloring mass are dried and hardened and the
color sticks are then ready for use.
When the color sticks are be used, they are put into a suitable solvent, as
water, alcohol, benzine, and the adhering coloring compound allowed to dissolve or
suspend therein. Soluble colors will give a more or less concentrated solution
which can be used for wash blue, writing and drawing inks, and dyeing matters.
If the mass adhering on the sticks contains insoluble colors the same is rubbed in a
suitable receptacle with a suitable quantity of. water or any other solvent and a
more or less concentrated suspension of the said color stuff with the binding
material is obtained which can be used for making aquards fresco and other
paintings. It is evident that according to the quantity of the solvent or the
time the compound is placed or rubbed therein any desired shade of the color can
be obtained.
For most purposes for which our color sticks are proposed color cakes have been
used heretofore which were rubbed with a wetted brush to received the required
liquid painting or coloring stuff. This tedious work is done away with by our color
sticks which are treated in the described simple manner and allow a greater
economy in using the coloring stuffs.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-
"
As a new article of manufacture, color sticks having on one or both end an
adhering portion of a mass composed of a color stuff mixed with or dissolved in a
suitable binding material and then hardened therewith substantially as and for the
purpose set forth.
