I, RICHARD GOULD of 10 Esher Street, Upper Kennington Lane, in the County of
Surrey, Builder, do hereby declare the nature of this invention to be as follows:-
The object of my invention is to obtain a cheap, sanitary and well covering distemper
that will when prepared keep for a lengthened period ready for use. To these ends I
employ the following ingredients or their chemical equivalents and mix them in water in
or near the proportions given viz.: To prepare 10 lbs. of my improved composition I
mix together 6 lbs. of whiting (gilder's whiting by preference) lb. of alum, lb. of
Epsom salts, 2 lbs. of water; adding ordinary dry colors as and when desired as at
present. When I desire to make my composition washable after application I add to
the above ingredients about 1 lbs. of copperas.

page_text: I, RICHARD GOULD of 10 Esher Street, Upper Kennington Lane in the County of
Surrey, Builder, do hereby declaro the nature of my invention, and in what manner
the same is to be performed to be particularly described and ascertained in and by
the following statement :-
The object of this invention is to provide a material for mixing with whiting and
color whereby an improved sanitary distemper may be formed, one which shall cover
well and keep for a lengthened period after preparation ready for use, and be cheaper
than the mixture of size with whiting and colors which is at present used.
A further improvement lies in rendering the material capable of forming with the
whiting and color a washable distemper without necessity of further admixture.
The material is composed of the following ingredients preferably used in the
proportions given.
Alum 1 part by weight, Epsom salts 1 part, starch 1 part with 5 parts water-The
ingredients are well stirred together when the alum and Epsom salts will for the
most part dissolve. I do not confine myself to mixing the ingredients mentioned
with the exact quantity of water here set down but have found such quantity to form
with the amount of dry whiting hereafter mentioned, a distemper of convenient
consistency. I may however use less or more without materially affecting the
result.
To render this compound suitable for the manufacture of so called washable
distemper I add to the above ingredients 3 parts of copperas.
Such materials will be preferably made up as described ready for use and when a
distemper is required to be made whiting with the requisite amount of color, when
color is used, is mixed with the above mentioned compound-preferably in proportions
of 6 parts by weight of whiting to 4 parts of the aforesaid mixture; or to 5 parts of
said mixture if containing copperas.
The whiting and color-is well stirred in the usual manner and the distemper is then
ready for use.
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. In the manufacture of distemper the combination with whiting of a mixture
comprising alum, Epsom salts and starch in proportions substantially as set forth.
2. In the manufacture of washable distemper the combination with whiting of a
mixture comprising alum, Epsom salts, starch and copperas in proportions substantially
as set forth.

page_text: 3. As a new and useful product of manufacture for the purpose set forth, the
combination of alum Epsom salts and starch with water in proportions substantially
as set forth.
4. As a new and useful product of manufacture for the purpose set forth, the
combination of alum, Epsom salts, starch and copperas with water in proportions,
substantially as set forth.
Dated this 2nd day of March 1888.
