BENJAMIN JOSEPH BARNARD MILLS of the firm of Harris and Mills of
23 Southampton Buildings in the County of Middlesex, Patent Agent "A NEW
OR IMPROVED CERAMIC COMPOSITION AND THE APPLICATION THEREOF TO VARIOUS
"
PURPOSES A communication to me from abroad by François Gillet of Paris in
the Republic of France
The Invention has for its object the production of a new or improved ceramic
composition or reconstituted lava and the application thereof to various purposes.
The composition is formed in principle of volcanic matters known as lava and
scoriæ pulverized and mixed with fluxes and with clays in suitable proportions
according to the various purposes to which it is to be applied.
For some purposes the following proportions may be used, volcanic matter
2 parts Flux 1 part plastic clay 1 part.
These proportions are varied according to the various applications desired to be
made of the material.
Any fluxes may be employed
The flux may be dispensed with in a composition equivalent to crockery ware.
The proportion of the flux is increased when it is desired to obtain a composition
capable of containing liquids.
The proportion of the clay is varied according as it is of a nature more or less
plastic.

page_text: In addition to these constituent elements or parts of the paste or composition
the right is reserved to introduce into the composition all materials which may
serve to alter or vary its colour and appearance.
The proportions of clay and flux being conveniently calculated the composition
may be employed and shaped by moulding, modelling, turning or compressing for
the manufacture of all kinds of ceramic products or goods for artistic or industrial
purposes.
The firing of the raw products varies according to the nature of the result to be
obtained.
Lastly, the right is reserved to ornament the products thus manufactured in any
suitable manner by enamelling, glazing, gilding, silvering or otherwise.
The proportions of the various constituents may also be varied as already
intimated without departing from the nature of the invention.

A NEW
OR IMPROVED CERAMIC COMPOSITION AND THE APPLICATION THEREOF TO VARIOUS
"
PURPOSES (A communication to me from abroad by François Gillet of Paris in
the Republic of France)
The Invention has for its object the production of a new or improved ceramic
composition or re-constituted lava and the application thereof to various purposes.
The composition is formed in principle of volcanic matters known as lava and
scoriæ pulverized and mixed with fluxes and with clays in suitable proportions
according to the various purposes to which it is to be applied.
For some purposes the following proportions may be used: Volcanic matter
2 parts-Flux 1 part-Plastic clay 1 part.
These proportions are varied according to the various applications desired to be
made of the material-Any fluxes may be employed-The flux may be dispensed
with in a composition equivalent to crockery ware. The proportion of the flux is
increased when it is desired to obtain a composition capable of containing liqui
The proportion of the clay is varied according as it is of a nature more or less
plastic.
In addition to these constituent elements or parts of the paste or composition
the right is reserved to introduce into the composition all materials which may
serve to alter or vary its color and appearance.
The proportions of clay and flux being conveniently calculated the composition
may be employed and shaped by moulding, modelling, turning or compressing for
the manufacture of all kinds of ceramic products or goods for artistic or industrial
purposes.
The firing of the raw products varies according to the nature of the result to be
obtained.
Lastly the right is reserved to ornament the products thus manufactured in any
suitable manner by enamelling glazing gilding silvering or otherwise.
The proportions of the various constituents may also be varied as already
intimated without departing from the nature of the invention.
Having thus described the nature of the said Invention and the mode in which
the same is carried into effect, I would have it understood that what I claim is,
The ceramic composition which the Inventor calls "reconstituted lava" formed
of pulverized volcanic matter known as lava and scoria mixed with fluxes and clay
or other equivalent plastic material, as also with coloring matters substantially as
above described. I also claim all applications of this composition.
In Witness whereof I the said Benjamin Joseph Barnard Mills have hereunto
set my hand and seal this third day of February in the year of our Lord
One thousand eight hundred and eighty three.
