page_text: LETTERS PATENT to Alphonse Baillif, Sculptor, of the city of Paris, in the
Republic of France for an Invention of IMPROVEMENTS IN THE METHOD OF,
AND IN THE COMPOSITION OF MATTER FOR INCRUSTING METAL TO REPRESENT
SCULPTURE, AND FOR ORNAMENTAL PURPOSES
PROVISIONAL SPECIFICATION left by the said Alphonse Baillif at the
Office of the Commissioners of Patents on the 28th March 1883.
ALPHONSE BAILLIF, Sculptor of the city of Paris in the Republic of France
"IMPROVEMENTS IN THE METHOD OF, AND IN THE COMPOSITION OF MATTER FOR
INCRUSTING METAL TO REPRESENT SCULPTURE, AND FOR ORNAMENTAL PURPOSES
"
The object of this invention is to coat metal ornaments with a hard composition,
rendering them when so coated similar in appearance to sculptured stone articles,
for use in various ornamental ways.
The process is as follows; having first selected some ornamental metal work
such as brass, iron, copper, or otherwise, it is previously well cleansed of any foreign
adherent substances, by thoroughly washing, and then drying it.
A composition of matter is then prepared consisting of Mendon white, dissolved
in clear water, to this is added glue made from leather cuttings, with the addition
of a little clear size, when these matters are thoroughly mixed the consistency
being a firm paste, the whole is diluted with clear water and is then subjected to
heat till it thickens as it reaches boiling point, the matter being kept stirred the
whole time so that no sediment is left and also to prevent burning.
Whilst the composition is hot it is poured over the metal ornament to be
encrusted.
Rolled bees wax cut in strips being placed round the ornament to keep the
liquid composition well over the surface of the ornament which is gently shaken
occasionally to prevent the formation of air bubbles and make the composition
close and firm, it is then allowed to dry in the cool air and when so dried it
presents a firın hard surface, this is then burnished with a burnisher, and the
fillets and ornainental lines and veins made to appear in the natural colour of the
metal, thus producing a graceful and pleasing effect.

The object of this invention is to coat metal ornaments with a hard composition,
rendering them when so coated, similar in appearance to articles of sculptured
stone; for use in various ornamental ways.
The process is as follows: having first selected some ornamental metal work
such as brass, iron copper and so forth, it is previously well cleansed of any foreign
adherent substances, by thoroughly washing and then drying it.
A composition of matter is then prepared consisting of Mendon white dissolved
in clear water to this is added glue made from leather cuttings, with the addition
of a little clear size
When these matters are thoroughly mixed, the consistency being a firm paste,
the whole is diluted with clear water which is subjected to heat till it thickens as
it reaches boiling point; the matter being kept well stirred the whole time so that
no sediment is left, and also to prevent burning; and whilst the composition is
still hot it is poured over the inetal ornament to be encrusted; rolled bees wax
cut into strips being placed round the ornament to keep the liquid composition
well over the surface of the ornament which is gently shaken occasionally to
prevent the formation of air bubbles and make the composition close and firm.
It is then allowed to dry in the cool air, and when so dried presents a firm hard
surface, this is then burnished with a burnisher, and the fillets or ornamental lines
and veins made to appear in the natural colour of the metal: thus producing a
graceful and pleasing effect.
In witness whereof I the said Alphonse Baillif have hereunto set my hand and
seal this twenty fifth day of September in the Year of Our Lord One thousand
eight hundred and eighty three.
