PROVISIONAL SPECIFICATION.
A New or Improved Non-poisonous and Permanent White Paint
or Varnish.
I, LEONARD HUNT, of 2, 4 and 6, Albert Bridge, Manchester, Manufacturing
Chemist, do hereby declare the nature of my said invention to be as follows:-
My invention refers to a new (white) paint or varnish which is non-poisonous,
and permanently retains its color. The base of such paint or varnish consists of
75 parts of sulphate of barium and 25 parts of sulphite of zinc, intimately mixed
together by precipitation. This base or mixture in being made into a permanent
white paint is first mixed with linseed oil, and by mechanical means worked into
a paste, to which is then added oil, turpentine and terebine to form a thick cream,
which then constitutes a non-poisonous permanent white paint.
In using the base for a permanent white varnish, I make it, in like manner
to the paint, into a paste with linseed oil, and, by adding mixed pale copal var-
nishes, reduce the same to a creamy or like consistency, which then constitutes my
improved permanent white and non-poisonous varnish.
The improved paint or varnish besides being non-poisonous is indestructible
by heat, and is unaffected by sulphuretted hydrogen, whereas the ordinary white
lead paint at present in use is decomposed by heat, and soon turns brown in an
atmosphere containing the slightest trace of sulphuretted hydrogen.

COMPLETE SPECIFICATION.
A New or Improved Non-poisonous and Permanent White Paint
or Varnish.
I, LEONARD HUNT, of 2, 4 and 6, Albert Bridge, Manchester, Manufacturing
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:-
My invention refers to a new (white) paint or varnish which is non-poisonous,
and permanently retains its color. The base of such paint or varnish consists in
100 parts of the substance of 75 parts of sulphate of barium and 25 parts of sulphite
of zinc, intimately mixed together by precipitation. This base or mixture in being

page_text: made into a permanent white paint is first mixed with linseed oil and by mechanical
means worked into a paste, to which is then added more oil, turpentine and tere-
bine to form the consistency of a thick cream; which then constitutes a non-
poisonous permanent white paint, the proportions of the oil, turpentine and tere-
bine varying with the use of the paint, or effect desired in the ordinary manner.
In using the base for a permanent white varnish, I make it (in like manner
to the paint) into a paste with, linseed oil, and by adding mixed pale copal var-
nishes, reduce the same to a creamy or like consistency, which then constitutes
my improved permanent white and non-poisonous varnish, the proportions of the
oil and copal varnishes being according to the effect desired in the ordinary manner.
The improved paint or varnish besides being non-poisonous is indestructible by
heat, and is unaffected by sulphuretted hydrogen, whereas the ordinary white-
lead paint at present in use, is decomposed by heat, and soon turns brown in an
atmosphere containing the slightest trace of sulphuretted hydrogen.
Having thus 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:-
1: A. paint, or varnish having for its base sulphate of barium and sulphite
of zinc in, or about, the proportions herein set forth.
