We CHARLES HENRY COIFFIER, Ivory Turner, and TпомAS ROWLAND JORDAN,
Engineer, both of 52 Gracechurch Street in the City of London, do hereby declare
the nature of this Invention to be as follows:-
Our Invention relates to a new product which can be employed for the
manufacture of articles usually made by Ivory turners, and other similar trades.
The Invention also relates to the process of preparing said product for making
imitations of Ivory, Tortoise-shell, Marble, Coral Malachite, Wood, etc.
In order to obtain this product, we take waste horn, or bone, and after well
washing and thoroughly scraping the same, we reduce it to powder, by means of a
suitable machine, and afterwards pulverize this powder in a machine known as
"Jordan's Patent Pulverizer," or other suitable machine capable of producing an
impalpable powder. Or, instead of horn, or bone, waste vulcanite, cork, glass,
alabaster, earths, coral, ivory, malachite, marble, etc, may be similarly treated, and
employed in lieu thereof. The powder is then placed in a steel mould (heated by
hot plates, gas, or other suitable means) and subjected to considerable pressure
under a screw, or hydraulic press. The block produced by the above process, may
then be again pulverized after being, if necessary, purified, or refined, in order to
deprive it of any impurities it may contain, after which the powder is dyed of any
desired color, by means of vegetable or mineral dye, and when the dyed powder is
perfectly dry, it is remoulded in steel moulds of any desired shape, or form, and
subjected to pressure. The blocks, after being taken out of the moulds, by which
the desired form is imparted, require only to be dressed, or finished, in the same
way as bronze castings. The blocks can be turned, and drilled, like metal, or wood,
or can be filed, or polished, like vulcanite.
In order to produce veined, or marbled products, ivory waste is employed, which
is first bleached by the action of oxygenated water, and after this bleaching,
(which extracts the gelatinous matter, and facititates the penetration of the dye)
the waste is dried, and made to absorb, (by heating) about the same proportion of
clear gelatine as that which has been already extracted, whereby the coloring
matter is perfectly fixed. By mixing the different pieces of dyed ivory, serving to
form the veins, with the dyed horn, or bone powder forming the base, the desired
marbled effects are obtained.

page_text: It is absolutely necessary, in moulding this powder, that no moisture should be
present, but that, on the contrary, it should be perfectly dry.
Any kind of surface ornamentation, or inlaying, either vegetable, or mineral, can
be employed with this kind of work, either by gluing the substance to be inlaid
upon the article and moulding it a second time; or by so disposing the inlaying
material upon the powder as to obtain the desired effect at the first operation.
When a lighter, as well as a more flexible, or elastic, material is required, we use
cork-dust pulverized, and oxygenated (if to be bleached) and dyed, and treated as
stated above for ivory waste, horn, or bone dust, or the other substances mentioned
herein. In this latter case, however, in order to agglomerate the powder, we use
egg albumen which gives the substance more body, without increasing the weight.

We CHARLES HENRY COIFFIER, (Ivory-turner) and THOMAS ROWLAND JORDAN
(Engineer) both of 52 Gracechurch Street, in the City of London, do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be. particularly described and ascertained in and by the following
statement:-
Our Invention relates to a new product which can be employed for the
manufacture of articles usually made by Ivory-turners, and other similar trades.
The invention also relates to the process of preparing said product for making
imitations of ivory, tortoise-shell, marble, coral, malachite, wood, etc.
In order to obtain this product we take waste horn and after well washing and
thoroughly scraping the same we reduce it to powder by means of a suitable
machine, and afterwards pulverize this powder in a machine known as " Jordan's
Patent Pulverizer," or other suitable machine capable of producing an impalpable
powder. Or, instead of horn, waste vulcanite, cork, glass, alabaster, earths, coral,
ivory, malachite, marble, etc, may be similarly treated, and employed in lieu thereof.
The powder is then placed in. a steel mould (heated by hot plates, gas, or other
suitable means) and subjected to considerable pressure under a screw or hydraulic
press. The block produced by the above process may then be again pulverized,
after being if necessary purified or refined in order to deprive it of any impurities
it may contain, after which the powder is dyed of any desired color by means of
vegetable or nineral dye, and when the dyed powder is perfectly dry, it is
remoulded in steel moulds of any desired shape or form and subjected to pressure.
The blocks, after being taken out of the moulds by which the desired form is
imparted, require only to be dressed or finished in the same way as bronze castings.
The blocks can be turned and drilled like metal or wood, or can be filed or polished
like vulcanite.
In order to produce veined or marbled products, ivory waste is employed, which
is first bleached by the action of oxygenated water, and after this bleaching
(which extracts the gelatinous matter and facilitates the penetration of the dye)
the waste is dried and made to absorb, (by heating) about the same proportion of
clear gelatine as that which has been already extracted whereby the coloring
matter becomes perfectly fixed. By mixing the different pieces of dyed ivory,
serving to form the veins, with the dyed horn powder forming the base, the
desired marbled effects are obtained. It is absolutely necessary in moulding this
powder that no moisture should be present but that on the contrary it should be
perfectly dry.
Any kind of surface ornamentation or inlaying, either vegetable or mineral, can
be employed with this kind of work, either by glueing the substance to be inlaid
upon the article and moulding it a second time, or by so disposing the inlaying
material upon the powder as to obtain the desired effect at the first operation.

page_text: When a lighter as well as a more flexible or elastic material is required, we use
cork dust pulverized and oxygenated (if to be bleached) and dyed and treated as
stated above for ivory waste, horn dust or the other substances mentioned therein.
In this latter case, however, in order to agglomerate the powder, we use egg
albumen which gives the substance more body without increasing the weight.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that
what we claim is
1st. The new product formed of dust of horn, vulcanite, ivory, coral, glass, earths,
marble, alabaster, malachite, cork, or other suitable material, and the application of
said product whether veined or colored or not, substantially as described.
2nd. The processes, substantially as described, for producing the substance
hereinbefore referred to from horn, or other suitable material pulverized to an
impalpable or fine powder by "Jordan's" pulverizing or other suitable machine
and compressed while hot, either in a dry state, or with the addition of a suitable
agglutinant, and colored, veined or otherwise, according to the substance required
to be imitated, substantially as described for the purpose stated.
