PROVISIONAL SPECIFICATION.
Improvement in the Manufacture of Oil Paints and Paint Medium.
MILES WILLIAMS Scholes Bridge Wigan Paint & Varnish Manufacturer do
hereby declare the nature of this invention for IMPROVEMENT IN THE
MANUFACTURE OF OIL PAINTS AND PAINT MEDIUM to be as follows:-
The improvement in the manufacture of oil paints and paint medium consists in
grinding ordinary colors & pigments or pigments prepared by my process
patented the 9th day of January 1889 & numbered 382 in an oil or medium
which I prepare from rosin or resin by distillation and termed rosin or colophony
oil, sweetened and fixed with hot or cold air & steam and which can be, if desired
a pale color, redistilled and bleached by the ordinary methods. The oil thus
obtained is treated or boiled with any suitable dryers to make it more siccative.
It can then be used alone as an oil medium for grinding the pigments into paints
by roller or other mills, or a proportion of boiled or raw linseed or other seed oils,
or boiled or raw oil foots or varnish foots or varnish gums can be previously
incorporated or used conjointly with it. The object is to obtain superior stiff oil
paint or putty by using a less costly medium than ordinary linseed or other seed
oil, and which can be "thinned or made ready for use by this means or by ordinary
"thinners." Such medium can also be used for varnishes and enamels.

Chemist 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 :-
The improvement in the manufacture of oil paints and paint medium consists in
grinding ordinary colors and pigments or pigments prepared by my process
patented the 9th day of January 1889 and numbered 382 in an oil or medium
which I prepare from rosin or resin by distillation and termed rosin or colophony
oil sweetened & fixed with hot or cold air and steam separately or conjointly and
which can be if desired a pale color-redistilled, and bleached by the ordinary
methods. The oil thus obtained is treated or boiled with any suitable dryers to
make it more siccative. It can then be used alone as an oil or medium for grind-
ing the pigments into paints or putty by roller or other mills or a proportion
of boiled or raw linseed or other seed oils or boiled or raw oil foots, varnish
foots or varnish gums can be previously incorporated or used conjointly with it.
I take a proportion say 5 tons of colophony or rosin oil obtained by the ordinary
method and temperature of distillation. I place this oil in a suitable wood or metal
vessel or tank and if desired treat it with chemicals solutions of 2% to 5% sulphuric
or other acid to bleach the oil & neutralize any excess of acids, alkalies &c. I then
add varying proportions from 10 to 25% of the seed oils, oil foots or varnish foots
and necessary & usual dryers and treat the whole with hot or cold air with or
without ordinary or superheated steam at a temperature of from 100° to 400° or
until the whole is incorporated, clarified & sweetened. The object is to obtain a
superior cheap stiff oil paint or putty by using a less costly medium than ordinary
linseed or other seed oils and which can then be "thinned or made ready for use

or enamels.
Having now more 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
1st. A superior stiff oil paint with other and cheaper medium than linseed o
other seed oils.
2nd. A superior cheap oil medium other than by linseed or other seed oil, for
the production with suitable pigments colors or gums, of paint, putty varnishes and
enamels.
3rd. The production of a cheap oil medium from resin, resin oil & utilization
therewith of oil foots, varnish foots.
