A NEW OR IMPROVED PROCESS IN MANUFACTURING AND ORNAMENTING CERAMIC PRODUCTS CHEMICALLY
Year: 1860

page_text: LETTERS PATENT to Charles André Chapuis, of 29,, Boulevart St.
Martin, Paris, in the Empire of France, Chemist, for the Invention of
"A NEW OR IMPROVED PROCESS IN MANUFACTURING AND ORNAMENTING
CERAMIC PRODUCTS CHEMICALLY."
Sealed the 28th August 1860, and dated the 7th March 1860.
PROVISIONAL SPECIFICATION left by the said Charles André Chapuis
at the Office of the Commissioners of Patents, with his Petition, on
the 7th March 1860.
I, CHARLES ANDRÉ CHAPUIS, of 29, Boulevart St. Martin, Paris, in the
Empire of France, Chemist, do hereby declare the nature of the said
Invention for "A NEW OR IMPROVED PROCESS IN MANUFACTURING AND ORNA-
MENTING CERAMIC PRODUCTS CHEMICALLY," to be as follows:-
The magnificent Chinese porcelain is the result of processes and a manu-
facture unknown excepting in China. Neither "savants" nor manufacturers
of porcelain, not even excepting the celebrated manufacturers of Sevres china,
have been able to discover the processes by which the beautiful crackle
vases, with the mosaic designs, are produced, objects of art so much sought
after by connoisseurs.
Certain experiments have led me to discover principles and processes
applicable to this branch of the art of manufacturing china, earthenware, or

page_text: porcelain, and my Invention consists of a new mode of decoration, which I
apply to ceramic objects, taking advantage of the porosity of their material,
and also of their coating for the application of the metallic solutions herein-
after mentioned.
By means of these processes I produce a regular decoration on large
vases and other objects having a mosaic character, and possessing all the
appearance and properties of crackle china.
For the purpose of obtaining designs in crackle, mosaic, & other various
decorations, I impregnate these bodies alternately in a hot and cold state with
ammoniacal or alkaline salts, or with acidulated liquids holding metals in
solution; the nature and employment of which I determine according to the
colors I wish to produce. For this purpose I make use of heating apparatus
of cast iron, or other metal. The metals which I employ in solution are, iron,
copper, silver, gold, platina, and others, such as rhodium, iridium, palladium,
osmium, ruthenium, and, in fact, all matters known in chemistry and applicable
for the purpose.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Charles André Chapuis in the Great Seal Patent Office
on the 4th September 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
ANDRÉ CHAPUIS, of 29, Boulevart St. Martin, Paris, in the Empire of
France, Chemist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventh day of March, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-third year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said, Charles André Chapuis, Her special licence that I, the said
Charles André Chapuis, my executors, administrators, and assigns, or such
others as I, the said Chapuis, my executors, administrators, and assigns,
should at any time agree with and no others, from time to time and at
all times thereafter during the term therein expressed; should and law-
fully might make, use, exercise, and vend, within the United Kingdom of
Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "A NEW OR IMPROVED PROCESS IN MANUFACTURING AND ORNA-
MENTING CERAMIC PRODUCTS CHEMICALLY," upon the condition (amongst others)
that I, the said Charles André Chapuis, my executors or administrators,. by

page_text: an 'instrument in writing under my, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said Inven-
tion, and in what manner the same was to be performed, and cause the same
to be filed in the Great Seal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Charles André Chapuis, do hereby
declare the nature of my said Invention, and in what manner. the same
is to be performed, to be particularly described and ascertained in and by the
following statement :-
The magnificent Chinese porcelain is the result of processes and a manu-
facture unknown excepting in China. Neither savants nor manufacturers of
porcelain, not even the celebrated manufacturers of Sévres china, have been
able to discover the processes by which these beautiful crackle vases, with the
mosaic designs, are produced, objects of art so much sought after by
connoisseurs.
Certain experiments have led me to discover principles and processes
applicable to this branch of the art of manufacturing china, earthenware, or
porcelain.
My Invention consists of a new mode of decoration which I apply to
ceramic objects, taking advantage of the porosity of their material, and also
of their coatings, for the application of the metallic solutions herein-after
mentioned.
By means of these processes I produce a regular decoration on large vases
and other objects having a mosaic character and possessing all the appearance
and properties of crackle china. For the purpose of obtaining designs in
crackle china, masaic, and other various decorations, I impregnate theso
bodies alternately in a hot and cold state with ammoniacal or alkaline salts, or
with acidulated liquids holding metals in solution, the nature and employment
of which I determine according to the colors I wish to produce. For this
purpose I make use of heating apparatus of cast iron or other metals. The
metals which I employ in solution are, iron, copper, silver, platina, and others,
such as rhodium, iredium, palladium, osmium, ruthenium, and, in fact, all
matters known in chemistry, and applicable for the purpose.
Having thus described the nature of the said improvements in ornamenting
china, and the manner in which my Invention is to be carried effect, I
desire it to be distinctly understood that what I claim and desire to secure by
the herein-before in parts recited Letters Patent is, a new mode of decoration
applied to ceramic objects when once manufactured, advantage being taken of
the porosity of their material, and also of their coatings under the influence of

page_text: the metallic.solutions as above described.. By. which new mode of proceeding
is produced a regular decoration on large vases and other objects having a
mosaic character and. possessing all the appearance and properties of crackle
spotted. china.
In witness whereof, I, Charles André Chapuis, have hereunto set my
hand and seal, this Twenty-second day of August in the year of our
Lord One thousand eight hundred and sixty.
