PROVISIONAL SPECIFICATION.
Improvement in the Manufacture of Paints and Varnishes and in the
Treatment of Materials in connection therewith.
HENRY TAYLOR 5 Windsa Road Forest Gate London E. Manufacturer do
hereby declare the nature of this invention to be as follows:-
Paints and varnishes are made more capable of resisting atmospheric changes
and of greater hardness and durability-also quickened in the drying by treating
rosin bitumen gum or pitches used for paint and varnish making with lime while in
a melted state. I use sufficient to kill or destroy any acid but not to cause
saponification.
I stir the lime in. Afterwards let the material cool down and set or proceed to thin
down at once with oil or any hydrocarbon now used into the consistency for use the
paint is required for. Coloured pigments or stains can be added as is the
custom.

COMPLETE SPECIFICATION.
Improvement in the Manufacture of Paints and Varnishes and in the
Treatment of Materials in connection therewith.
HENRY TAYLOR 5 Windsa Road Forest Gate London E. Manufacturer 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 invention consists in producing a better paint or varnish usually made from
(or partially made from) rosins pitches bitumens or gums by treating any of these
with lime while in a melted or liquid state.
I sprinkle in from about 5 to 10 per cent. of lime (I prefer to use the lime fresh
slacked) and well stir into the mass then allow the material to cool down into a solid
state again.
I do not bind myself to exactly 5 per cent. a little less or in some cases a
little more than 10 per cent. may be used advantageously.
The lime by stirring into the rosins pitches bitumen or gums until partially cool
or in a semi solid condition acts chemically on the material by destroying any acids
and absorbing all greasy or oily matter. It also considerably hardens the material
making the paint or varnish made from these materials capable of resisting heat
better also improving the drying properties.
Or I use the lime as before stated and instead of allowing the rosins pitches
bitumen or gums to cool into a solid state I proceed to thin down at once with
the usual oils turpentine naptha or other solvents used for paint or varnish
making to the proper consistency for their various uses. The lime after depositing
with grit and other impurities leaving a clear bright varnish which can be used as
a varnish.
Or by the addition of colouring pigments be made into a paint by the usual
method of grinding by rolls or mills.
Or I obtain a similar result by treating varnish already made with slacked lima
by adding from 5 to 10 per cent. by weight or thereabouts and well agitating by
stirring or shaking then allowing the lime to settle down. The clear varnish will
then become quicker and harder drying.

page_text: MATERIALS FOR PAINT OR VARNISH MAKING.
My method of preparing the rosins pitches bitumens or gums for sale to the
trade to be manufactured into paints or varnishes is as described in paragraph
No. 2.
Having now fully described my invention I claim my invention to consist of
The addition of lime in varnish or paint manufacture.
