AN IMPROVED COMPOSITION SPECIALLY APPLICABLE FOR USE FOR SANITARY, PICTORIAL, DECORATIVE, AND BUILDING PURPOSES
Year: 1872

page_text: LETTERS PATENT to Jesse Rust, of Bond Street, Vauxhall, in the
County of Surrey, Glass Manufacturer, for the Invention of
"AN IMPROVED COMPOSITION SPECIALLY APPLICABLE FOR USE FOR SANITARY,
PICTORIAL, DECORATIVE, AND BUILDING PURPOSES."
Sealed the 20th August 1872, and dated the 22nd February 1872.
PROVISIONAL SPECIFICATION left by the said Jesse Rust at the
Office of the Commissioners of Patents, with his Petition, on the
22nd February 1872.
I, JESSE RUST, of Bond Street, Vauxhall, in the County of Surrey,
Glass Manufacturer, do hereby declare the nature of the said Invention
for "AN IMPROVED COMPOSITION SPECIALLY APPLICABLE FOR USE FOR SANITARY,
PICTORIAL, DECORATIVE, AND BUILDING PURPOSES," to be as follows:
-
Firstly. I take glass of any kind (old and broken will however answer
and be the most economical for my purpose), I grind this to powder and
mix it with the same weight of sand or ground flints (though more or
less sand or ground flints may sometimes be used). This mixture I then

page_text: place in a reverberatory or other suitable furnace and fuse the mass
together, and when fused and cold I reduce the same to powder, and this
powder I afterwards press into moulds in a dry or in a damped state
by adding water or any glutinous liquid (such as starch, glue, and
silicate of soda).
Secondly. These blocks or moulded pieces, small or large, I place in a
potter's or such like kiln and bake them in the same way as pottery ware;
when cold they are fit to use and form an impervious material, which
may be polished, painted, glazed, or decorated like fictle ware.
When I want a cheaper material I take the fused mixture of glass
and sand or ground flints as it comes from the reverberatory furnace,
and I reduce it to powder and then mix therewith two parts (or more)
of sand or ground flints, and one (or thereabouts) of china clay or other
clay, and this I press into moulds as before and mix with glutinous
liquid as before, and then treat the same in manner above described
under head "secondly."
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Jesse Rust in the Great Seal Patent Office on
the 22nd August 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JESSE
RUST, of Bond Street, Vauxhall, in the County of Surrey, Glass Manu-
facturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-second day of February, in the
year of our Lord One thousand eight hundred and seventy-two, in the
thirty-fifth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Jesse Rust, Her special licence that
I, the said Jesse Rust, my executors, administrators, and assigns, or
such others as I, the said Jesse Rust, 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 lawfully 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 "AN IMPROVED COMPOSITION SPECIALLY
APPLICABLE FOR USE FOR SANITARY, PICTORIAL, DECORATIVE, AND BUILDING

page_text: PURPOSES," upon the condition (amongst others) that I, the said Jesse
Rust, my executors or administrators, by 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 Invention, 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 Jesse Rust, 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:—
Firstly. I take glass of any kind (old and broken will, however,
answer and be the most economical for my purpose), I grine or reduce
this to powder and mix it with the same weight of sand or ground flints,
though more or less sand or ground flints may sometimes be used. This
mixture I then place in a reverberatory or other suitable furnace and
fuse the mass together, and when fused and cold I reduce the same to
powder, and this powder I afterwards press into moulds in a dry or in
a damped state by adding water or any glutinous liquid (starch, glue,
and silicate of soda, for instance, being very useful for my purpose).
Secondly. These blocks or moulded pieces (small or large) I place in
a potter's or such like kiln and bake them in same way as pottery
ware. When cold they are fit to use and form a material which may
be polished, painted, glazed, or decorated like fictle ware.
Thirdly. When I want a cheaper material I take the fused mixture
of glass, sand, or ground flints as it comes from the reverberatory furnace
and I reduce it to powder and then mix therewith two parts (or more)
of sand or ground flints and one or thereabouts of china clay or other
clay, and this I press into moulds as before and mix with water or
glutinous liquid as before, and then treat the same in manner above
described under head "secondly."
For sand I can, when desired, use any analogous material, such as
ground sandstone, for instance, and for or in addition to glass or flint I
can use analogous material, such as felspar or iron slag or iron furnace
refuse.
In order to produce blocks or pieces of material coloured throughout
their substance I introduce the colouring substances used by glass

page_text: manufacturers for colouring glass, such as may be suitable for producing
the required colour by placing the same in the reverberatory or other
suitable furnace, the process of reducing to powder, baking, and
polishing being as applicable to these coloured blocks as to those not
coloured. In some cases where superiority of material is not required
it may not be necessary to grind or paint the glass before fusing it with
the sand. Also I can mix the glass (or analogous material) with the
sand (or analogous material) or sand and clay and press the same into
blocks or pieces and bake and treat the same as described under the
heads "secondly" and "thirdly" as circumstances may render desirable.
Having now particularly described and ascertained the nature of the
said Invention, and in what manner the same is to be performed or
carried out in practice, I hereby declare that I claim, the Invention of
"An Improved Composition specially applicable for Use for Sanitary,
Pictorial, Decorative, and Building Purposes," in. which Invention the
mixing of glass (or analogous material) hercin-before mentioned with
the sand (or analogous material) herein-before mentioned (or the same
mixed with clay) and treating them as herein-before described are
important and peculiar features.
In witness whereof, I, the said Jesse Rust, have hereunto set my
hand and seal, this Twenty-first day of August, in the year of our
Lord One thousand eight hundred and seventy-two.
