IN THE PRODUCTION OF MURAL FRESCO PAINTINGS, AND IN THE DECORATION OF

PROVISIONAL SPECIFICATION left by the said Charles Brock at
•
the Office of the Commissioners of Patents, with his Petition, on
the 22nd June 1875.
I, CHARLES BROOK, of Saint Mary Church, in the County of Devon,
Manager of the Works of the Watcombe Terra-Cotta Olay Company,
Limited, do hereby declare the nature of the said Invention for
“IMPROVEMENTS IN THE PRODUCTION OF MURAL FRESCO PAINTINGS, AND IN THE
DECORATION OF FLAT SURFACES, ALSO OF BUSTS, STATUETTES, AND OTHER POTTERY,'
to be as follows:-
"
My Invention consists in producing mural fresco paintings, and in
decorating flat surfaces, also busts, statuettes, and other kinds of pottery,.
whether useful or ornamental, by a process which renders such paintings,
or decorations imperishable.

page_text: The process is as follows:-I apply various colored earths and metallic
oxides to the surface of the articles to be decorated at a particular stage
of their manufacture, that is to say, when they are in the state known
to potters as the "white" state before the bisque fire, and I use with
the said earths and oxides a vegetable matter, such, for example, as
vegetable gums, which act both as a flux and purifier.
The articles operated upon are afterwards burnt in an oven at a high
temperature, the result being a beautiful bisque effect, free from smear
or glaze, and in fact imperishable frescoes.
I
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said Charles Brock in the Great Seal Patent Office

Seal Patent Office within six calendar months next and immediately

NOW KNOW YE, that I, the said Charles Brock, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertaineḍ in and
by the following statement thereof, that is to say :-
My Invention consists in producing mural fresco paintings, and in
decorating flat surfaces (tiles, for example) also busts, statuettes, and
other kinds of pottery, whether useful or ornamental, by a procèss
which renders such paintings or decorations imperishable.
The process is as follows:-I apply various colored earths and metallio
oxides to the surface of the articles to be decorated at a particular stage
of their manufacture, that is to say, when they are in the state known
to potters as the "white state" before the bisque fire, and I use with
the said earths and oxides a vegetable matter, such, for example, as
vegetable gums, which act both as a flux and purifier.
The articles operated upon are afterwards burnt in an oven at a high
temperature, the result being a beautiful bisque effect, free from smear
or glaze, and in fact imperishable frescoes.
Mural fresco decorations can be produced in this manner without
limit as to size.
And having now described the nature of my said Invention, and in
what manner the same is to be performed, I declare that I claim,
producing mural fresco paintings and decorating flat surfaces, busts,
statuettes, and other pottery, as herein-before described.
In witness whereof, I, the said Charles Brock, have hereunto
set my hand and seal, this Thirteenth day of December, One
