PROVISIONAL SPECIFICATION.
Artificial Stone, Bricks, Tiles, and the like.
We, JOHN GASKELL, of Rutherglen, Scotland, Potters Manager, and WILLIAM
ROBINSON, of Windle, near St. Helens, Lancashire, Brick Manufacturer, do
hereby declare the nature of this invention to be as follows:-
This invention has reference to the utilization of the waste of glass works,
namely, the ground sand, glass, and sulphate of iron, produced in glass grinding
and polishing, and to its application and conversion to a useful and commercial
material or article.
According to this invention there is produced from this waste glass sand and
sulphate of iron (the product of the ordinary process of grinding and polishing glass)
a valuable and useful article or manufacture, namely, stone in the form of blocks,
slabs, bricks, or tiles suitable as building material for building purposes, and other
purposes to which stone, bricks, or tiles are at present applicable.
In producing blocks, bricks, or tiles from the waste product above specified,
according to this invention, the material is formed into such blocks or bricks in
moulds, or moulded or otherwise, and then subsequently rendered hard and strong
by heat. It may be moulded in any plain form, or in ornamental forms.
In carrying out the invention, we may use amongst other things for the
purpose of assisting in and expediting the process of manufacture, a flux of any
suitable kind, and this may in some cases be used to render the blocks, bricks, or
tiles produced, harder and more durable; and in some cases they may be glazed.
A suitable flux may consist of barytes, sulphate of lime, granite and clay; but
any other flux of an analogous or suitable kind may be used, this one being merely
given as an example.
In carrying out this invention, we may use in conjunction with the material or
materials above specified any other material or substances.
The blocks, bricks, or tiles may be burnt in a suitable kiln, and when sufficiently
burnt are cooled and removed.

COMPLETE SPECIFICATION.
Artificial Stone, Bricks, Tiles, and the like.
We, JOHN GASKELL, of Rutherglen, Scotland, Potters Manager, and WILLIAM
ROBINSON, of Windle, near St. Helens, Lancashire, Brick Manufacturer, 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:
This invention has reference to the utilization of the waste of glass works,
namely, the ground sand, glass and oxide of iron produced in glass grinding, and
polishing, and to its application and conversion to a useful and commercial material
or article.
According to this invention there is produced from this waste glass sand and
oxide of iron (the product of the ordinary process of grinding and polishing glass)
a valuable and useful article or manufacture, namely, stone in the form of blocks,
slabs, bricks, or tiles, suitable as building material for building purposes, and other
purposes to which stone, bricks, or tiles are at present applicable.

page_text: In producing blocks, bricks, or tiles from the waste product above specified,
according to this invention, the material is formed into such blocks or bricks in
moulds, or moulded, or otherwise, and then subsequently rendered hard and strong
by heat. It may be moulded in any plain form, or in ornamental forms.
In carrying out the invention, we use by preference in the process of manufacture,
for assisting in the production of the articles or ware, a flux of any suitable kind;
but if the blocks or ware be hard pressed and moist, no extraneous matter need be
added to the waste material. This also tends to render the stone blocks, bricks or
tiles as produced, harder and more durable. The ware, when desired, may be glazed
or enamelled in any of the known ways.
A suitable flux may comprise barytes, sulphate of lime, granite and clay; but
any other flux of an analogous or suitable kind may be used, this one being merely
given as an example.
Samples of materials or mixtures according to this invention used in the
manufacture of the wares containing a flux of the nature just described, are as
follows, the parts or proportions given being by weight:-
:-
The residual or waste material
Barytes or sulphate of lime
Crushed granite

The above sample mixtures will be found very suitable and economical,
provided of course the different materials or any of them have not to be conveyed
any great distance; but of course, as already stated, the proportions may be varied,
and other fluxing materials of any known suitable kind substituted, according to
requirements, or the condition under which the manufacture is carried on.
The mixture No. 1 is one that can be used with advantage in making bricks or
ordinary building blocks; whilst that under No. 2 is the more useful for making
artificial stone or higher class and fancy ware, as by using it, the product is white
or of a whiter nature than the others, and consequently generally more suitable as
regards colour for these particular wares or purposes.
The materials may be mixed and made up and moulded into blocks, bricks, or
other form, as is now done with bricks and like wares, that is, they may be mixed
and made up or moulded in a semi-dry or a plastic condition; or they may be
worked by the wet method.
The blocks, bricks, tiles or wares, may be burnt in a suitable kiln, and when
sufficiently burned, are cooled and removed. The burning is better carried on
under a greater temperature than that employed for burning ordinary bricks. As
for instance, the temperatures and kilns employed, under and by which the burning
may advantageously be effected, are those used for burning blue-bricks. The
higher the temperature employed, the harder will be the bricks or other ware
produced.
In carrying out this invention, we may use in conjunction with the material or
materials above specified any other material or substances.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. The herein described new or improved manufacture, namely, artificial stone,
bricks, tiles, or other wares, made of residual or waste material, the product of the
ordinary process of grinding and polishing glass, and a suitable flux or fluxing
material or materials, and burnt in a kiln.
2. Artificial stone, bricks, tiles, and other wares, made of the waste material
and the fluxing materials, burnt in a suitable kiln, as herein more particularly
specified.
3. The herein described new or improved manufacture, namely, blocks, bricks,
tiles, or other ware, made of the residual or waste material specified (the product
of the ordinary process of grinding and polishing glass), said material being
moulded into forms of the blocks or ware required, and burned in kilns ;
substantially as described.
