TAUL CARRE, nemist,

Lady Cove
France.
I, ALFRED JULIUS BOULT, of 111, Hatton Garden, in the County of London,
Chartered Patent Agent, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a composition adapted to be used as a paint or coat-
ing for rendering materials uninflammable.
The composition is absolutely harmless, even to the most delicate colours, and
may be applied to wood, furniture, etc., to fabrics of all kinds, curtains, gauze,
silk muslin etc. to theatrical scenery, large canvasses, packing paper, lamp shades,
cases etc. and generally to any material liable to catch fire."
The composition when used only to impregnate the above materials, without
altering their colour or appearance consists of a mixture of 100 parts of water
with say 4 to 8 parts of boracic acid, and 15 to 50 parts of sulphate, chlorate
or carbonate of ammonia, used separately or altogether according to the nature of
the material to be rendered fire proof, and of 1 to 5 parts of borax. This com-
position is preferably used at a temperature of from 70 to 80° C.
When the composition is used to render a material incombustible and at the
same time to colour it, the substance may be dissolved in a mixture of 100 parts
of water and 50 parts of hide glue. Then it is preferably used at a temperature
of from 40 to 50° C. and applied in one or more layers, the desired colour being
incorporated with it together if desired with white lead, zinc-white, siccative oil,
essence of turpentine etc.
Where the above proportions of materials give good results they may be con-
siderably modified according to the treatment desired.

A communication from PAUL CARRÉ, Chemist, of 139, Rue Lafayette, Paris,
France.
I, ALFRED JULIUS BOULT, of 111, Hatton Garden, in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention and in
LD

page_text: what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to a composition adapted to be used as a paint or coat-
ing for rendering materials non inflammable.
The composition is absolutely harmless, even to the most delicate colours, and
may be applied to wood, furniture, etc., to fabrics of all kinds, curtains, gauze,
silk muslin etc., to theatrical scenery, large canvasses, packing paper, lamp shades,
cases etc., and generally to any material liable to catch fire.
The composition when used only to impregnate the above materials, without
altering their colour or appearance consists of a mixture of 100 parts of water
with say 4 to 8 parts of boracic acid, and 15 to 50 parts of sulphate, hydrochlorate
or carbonate of ammonia, used separately or altogether according to the nature of
the material to be rendered fire proof, and of 1 to 5 parts of borax.
This com-
position is preferably used at a temperature of from 70 to 80° C.
When the composition is used to render a material incombustible and at the
same time to colour it, the substance may be dissolved in a mixture of 100 parts
of water and 50 parts of hide glue. Then it is preferably used at a temperature
of from 40 to 50° C. and applied in one or more layers. When the composition is
to be used with oil paint, it is necessary to mix the above ingredients with white
lead, zinc white, or other substances for paints; with linseed oil to obtain a homo-
geneous paste as in the case of an ordinary paint.
This paste then is fireproof and can be used as a mixture with sicative oil and
turps as usual.
The above proportions may be modified according to requirements.
Having now particularly described and ascertained the nature of the said inven-
tion as communicated to me by my foreign correspondent and in what manner the
same is to be performed, I declare that what I claim is;-
1. A fireproof paint or composition formed of an aqueous mixture of boracic
acid, sulphate, hydrochlorate or carbonate of ammonia and borax substantially as
described.
2. A fire proof paint or composition formed of an aqueous mixture of hide glue,
boracic acid, sulphate, hydrochlorate or carbonate of ammonia, borax and colour-
ing matter substantially as described.
3. The fireproof paint or composition formed with or without colouring matter
substantially as and in the proportions described.
