of the Commissioners of Patents, with his Petition, on the 23rd
November 1875.
I, HENRY BAGGELEY, of Fulham, in the County of Middlesex, Manu-
facturing Chemist, do hereby declare the nature of the said Invention
for "A NEW OR IMPROVED COMPOUND OR MATERIAL SUITABLE FOR BUILDINGS AND
OTHER STRUCTURES, PAVEMENTS, AND OTHER USEFUL PURPOSES; ALSO AN IMPROVED
Glaze and CemENT FOR THE SAME, APPLICABLE TO VARIOUS USEFUL PURPOSES,” to
be as follows:-
This Invention consists first of a new or improved compound or
material suitable for use in the forms of bricks, tiles, columus, steps,
mouldings, and the like, for building purposes, also as a paving material
to be used in the form of blocks, slabs, frames, or otherwise in com-
bination or not with other materials for paving, or covering roads,
streets, footpaths, skating rinks, and other surfaces, also as a substitute
for iron plates in the construction of ships and other structures.

page_text: In manufacturing this pecular compound or material I employ the
following ingredients, or their equivalents in or about the proportions
given, namely,—
Copper dross
Brasses or clinkers
Limestone or pearl ash
Ground flint
Plaster of Paris
Nitre

12 lbs.

4 ounces.
These ingredients are to be fused or melted together in a furnace, and
the molten mass is then to be run into moulds of the desired shape,
according to the nature of the articles to be produced, and. then allowed
to cool and harden; or in lieu of melting the before-mentioned
ingredients I reduce them to a fine state of division by grinding, and I
moisten the powder with a sufficient quantity of water to reduce the
mass to a plastic condition, in which state it may be applied to walls
and other surfaces in the form of plaster, or be moulded and compressed
to any required form, and then allowed to set or harden. The said
material may be toughened and rendered pliable by the addition to the
before-mentioned ingredients before being fused or melted of about
32 lbs. of metallic copper, or an equivalent proportion of copper ore.
By this means I obtain plates or slabs which may be substituted for iron
plates in the construction of ships and other structures where iron is
now largely employed.
Secondly. Of a peculiar glaze, which although specially applicable to
the ornamenting or glazing of the surface of the berein-before described
new compound or material, may also be applied to the glazing of other
surfaces capable of withstanding the requisite temperature, such as
cooking utensils, for example. This peculiar glaze consists of the
following ingredients or their equivalents in or about the proportions
given, namely,—

page_text: When a fine white glaze is required I prefer to use white sand, and
to add about 2 lbs. of arsenic of commerce. The whole of the said
ingredients are to be reduced to a fine state of division, well mixed and
brought to about the consistency of thick cream by the addition of
water thereto. The glaze is then to be applied to the surface of the
compound before described, or to any other suitable surface by a brush
or otherwise, and is then to be subjected, say from five to fifteen
minutes, to a temperature of about 6000° Fahrenheit, by the aid of a
portable or other furnace. By running the said glaze into moulds
blocks or other articles may be produced therefrom of great hardness,
and these may be coloured or ornamented by the addition of pigments
to the glaze.
Thirdly. Of an improved cement specially applicable for uniting or
holding together blocks or other articles of the before-mentioned
compound or material, and also applicable as a strong cement for
general purposes. This peculiar cement consists of the following
ingredients or their equivalents in or about the proportions given,
namely
