PROVISIONAL SPECIFICATION.
New or Improved Artificial Granite and Process for the Manufacture
of the same.
I, REGINALD HADDAN, of the Firm of Herbert Haddan & Co., of 18, Buckingham
Street, Strand, W.C., London, Patent Agent, do hereby declare the nature of
this invention, a communication to me from abroad by la Société Berthe & Cié,
of Paris, in the Republic of France, Manufacturers, to be as follows:-
The object of this invention is a new or improved artificial granite.
The composition of the product can vary both in the substances used as in
their proportions; as an example the different materials which may be employed
for the construction of a bath made on an iron frame, solid or hollow as required,
are the following:-
1
5. Sand.
6. The waste produced in the manufacture of the substance (glass and flint)
reduced into dust so that only very little cement as agglutinant matter is required.
7. Grey or white cements.
These different materials are mixed in varied quantities, according as the
objects will or will not be exposed outside or for baths accordingly as the same
are to contain soft water, mineral water or sulfide of sodium. The color of the
All the substances mentioned herebefore are
product is also to be considered.
crushed very small then sifted and divided according to size, then washed and
sterilized by means of antiseptic products.
In order to polish the product thus obtained, glass and flint of the same hard-
ness are associated. For instance a very hard glass combined with a very soft
flint would give a result detrimental to the polishing.
The product is not cast in moulds as is the case with terra-cotta or glass plates
obtained by melting; the product is manufactured by hand by bearing on plates
serving as partial moulds.
The objects in which the glass is in the proportions varying between 50
and $3 per cent. are submitted to acid baths (sulphuric, hydrochloric and others)
of which the strength and the immersion duration are measured.
The present invention consists therefore chiefly in using the glass waste cold.
The basis of the various kinds of imitation granite of this invention is the glass
with which some or all of the before mentioned materials are incorporated.
Manufactured completely cold, the product is not submitted to any heating
and after being dried for some days can easily be polished.

In the product the course can not be seen; that is the cement incorporated
with the glass dust which gives a very great consistence, avoids cracking and
avoids the stains in bath made of the product.

page_text: The usuages of the product are numerous in consequence of its solidity, its
proof against atmospheric or chemical influences, its facility of cleaning and so
on. Its chief use is for baths, and hygienic apparatus, pans, lavatories, chimneys,
office utensils, paper-presses, inkstands, etc. and in architecture it furnishes
excellent material for construction and polychrom decoration, bricks, tiles, rails,
balustrades, pillars, funeral monuments, statues, fountains and so on.

New or Improved Artificial Granite and Process for the Manufacture
of the same.
I, REGINALD HADDAN, of the Firm of Herbert Haddan & Co., of 18, Buckingham
Street, Strand, W.C., London, Patent Agent, do hereby declare the nature of
this invention, a communication to me from abroad by la Société Berthe & Cié,
of Paris, in the Republic of France, Manufacturers, and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:-
The object of this invention is a new industrial product to which the name
granitine has been given by my correspondents.
The composition of the product can vary both in the substances used and in
their proportions. The following is a list of the 8 different materials which may
be employed for the construction of a domestic bath of granitine.
1. An iron frame, solid or hollow as required.
2. Flints.
3. Quartz.
4. Glass.
5. Cork.
6. Sand.
7. The waste glass and flint produced in the manufacture of the substance,
reduced to dust.
8. Grey or white cements.
By the use of ingredient No. 7 less cement is necessary than would otherwise
be required.
These different materials 2-8 are mixed in varied quantities, according as
the article made therewith is or is not to be exposed in the open, or whether,
like a bath, it is to contain or receive soft water, mineral or saline water, or
water containing sulphide of sodium; in which cases the proportions of certain
ingredients are restricted and those of certain others increased.
The choice of color is also to be considered. The ingredients 2 to 7 above
mentioned, are divided or crushed very small, then sifted and sorted into sizes,
then washed and sterilized by means of antiseptic products.
In order that the product may be susceptible of being polished, glass and
flint of the same hardness are associated. For instance, a very hard glass com-
bined with a very soft flint would give a result detrimental to polishing.
The products are not cast in moulds as is the case with terra-cotta or molten
glass ware; they are manufactured by hand while temporarily supported at
different points by suitable frames, walls or supports, serving as partial moulds.
Articles in the manufacture of which glass is used in the proportions varying
between 50 and 85% are submitted to acid baths (sulphuric, hydrochloric and
others) the strength and the duration of immersion being controlled.

consequently of a density of 1,180, the acid must be diluted in the proportion of

the article will polish easily with levigated emery.
The invention consists chiefly in using the glass waste in a cold state. The
basis of the construction of all articles of granitine is glass, with which some or all
of the before mentioned materials are incorporated.
Manufactured throughout completely in a cold state, the product is not sub-
mitted to any heating or baking, but is allowed to dry and set for a few days
and can then be easily polished.
The menstruum of this improved product is not perceivable; that is the
cement incorporated with the glass dust is not separately visible. This cement
gives very great coherence, avoids cracking, does not stain, requires no expense
for maintenance, and retains heat. The cements employed are preferably slowly
hardening Grenoble cements, of the Porte de France brand or Portland cement
can also be used.
The following are examples of the proportions of materials used in the manu-
facture of various articles:-

This material is suitable for very numerous uses in consequence of its solidity,
its quality of proof against atmospheric or chemical influences, facility for
cleaning and so on. Among its chief uses are for: hygienic apparatus, seats,
wall linings, and pavement, for toilet-rooms, lavatories, and elsewhere where
perfect cleanliness is necessary, balneary apparatus, and specially domestic
baths. The improved product can be used to replace marble for mantle pieces
and fire places. It can also serve for making office utensils, paper weights,
ink-stands etc. It also furnishes excellent material for polychromatic con-
structions, bricks, tiles, strings, pilasters, hand-rails, balustrades, pillars, and
other decorative objects, mortuary monuments, statues, fountains and the like.
Having now particularly described and ascertained the nature of this invention,
and in what manner the same is to be performed, I declare that what I claim is:-
1. The improved product obtained by the incorporation in a cement mortar of
different pulverized materials, but specially of glass waste, mixed in a cold state,
and subsequently polished if required.
