PROVISIONAL SPECIFICATION.
An Improved Material for Making Whitewash, Colorwash, and
Water-color Paints.
I, JOHN JAMES CARR of 59 Victoria Road Scarborough in the County of York
Painter and Decorater do hereby declare the nature of this invention to be as
follows:-
A composition of whiting and other suitable white substances also all kinds of
colors usually used for paints and colorwashes mixed or ground together with any
kind of size or gluetainous medium used for the purpose of binding such colors and
white substances when used as watercolors paints or colorwashes, then dryed by air,
heat, or both afterwards ground or made into a powder or small particles so that when
it is required for use it is to be mixed with simple water instead of the usual medium
of size.

COMPLETE SPECIFICATION.
An Improved Material for Making Whitewash, Colorwash, and
Water-color Paints.
I, JOHN JAMES CARR, of 59 Victoria Road, Scarborough, in the county of York,
Painter and Decorator, 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 :—
My said improved material consists in a composition or preparation obtained by
combining Whiting and other suitable white substances, (such as Paris white,
Permanent white, White lead, Zinc white, and Barytes (Sulphate of Baryta); Lime
being excepted), also color or colors usually used for paints and color-washes, with
any kind of size, gum, starch, or other glutinous material, the whole (or when
combined) being mixed or ground together, or each color and white substance may be
mixed and ground separately with the size, gum, starch, or other glutinous material,
such glutinous material being employed for the purpose of binding the said colors and
white substances to prevent the improved material rubbing-off when touched, when
used as water-color paints, or color washes.
The composition or preparation is then dried by air, heat or both and is afterwards
ground into a powder or loose state; or each color, white substance and glutinous
material or substance may first be ground into powder, and such afterwards mixed in
suitable proportions, so that when it is required to use the composition as distemper,
color-wash or water-color paint it is only necessary to add water (instead of the
usual medium of size) and mix it with the composition or preparation, which is then
ready for use.
In making or manufacturing my improved material I prefer to reduce separately
the white substances, colors, or glutinous materials to a fine powder by crushing or
grinding either by hand or machinery, I then add 1 part of the glutinous powder
to 42 parts of powdered whiting or color; I then shake or work the said materials
through sieves or mixing machinery for the purpose of ensuring the uniform mixing
of the glutinous substance and the powdered whiting or colors.
Or I may take the white substances, colors, glue or any of its equivalents as set
forth, and after making size by dissolving the glutinous substance used with water
(preferably bot) I then put any quantity of dry colors or whiting into a tub, mixing
machine, or other suitable receptacle and with sufficient of the liquid size added I
[Price Ad 1

page_text: mix or knead the substances into a stiff paste, 1 then put the paste into suitable
moulds or pans to be dried by hent, or air, or both. When the composition has
become dry it is then taken and crushed or ground into powder or a loose state.
The proportion I prefer to use of binding or glutinous material to the colors
and white substances is 1 part of glue or its equivalent to 42 parts of whiting
or colors, but I do not confine myself to any particular proportion.
The said material may be packed and sold in boxes, tins, barrels or in any other
suitable manner, as a dry powder or in a loose state, and as a preparation requiring
nothing adding to bind it as a distemper or water-color paint when mixed with water
as set forth, thereby enabling unskilled persons as well as others to make a fast
distemper or water-color paint without the addition of size.
When it is desired to have a distemper or water-color paint that will keep or
last a long time without decomposing; after the composition has been mixed with
water I add to the dried powders about 100th part of powdered "Borax"
or its
equivalent of any chemical having an antiseptic property, to prevent the glutinous or
binding material decomposing.
I may use the white substances mixed or separately and in any proportion as may
be required for different purposes, some kinds of work requiring different proportions
to gain the best results.
I may also mix any of the said white substances with any proportion of any color
or colors to produce any tint or shade of color as well as the pure or unmixed
colors.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1. The manufacture and use of a dry, loose or powdered material as and for the
purposes substantially as herein setforth.
2. The combination and use of white substances, colors, and binding or glutinous
materials as and for the purposes substantially as herein setforth.
