of the Commissioners of Patents on the 9th October 1877.
"
HENRY BAGGELEY, of the Firm of Baggeley and Green, of Saffron Walden, in the
County of Essex, Manufacturing Chemists. A NEW OR IMPROVED COMPOUND
OR COMPOSITION FOR THE MANUFACTURE OF BRICKS, TILES, AND OTHER SIMILAR
ARTICLES."
This Invention relates to a peculiar compound or composition suitable for the
manufacture of bricks, tiles, and other similar articles, the said articles manufactured
therefrom being more durable, and absolutely impervious to moisture.
According to my Invention I prepare a compound or composition composed of the
following ingredients in or about the proportions given, that is to say :-
300 parts by weight of chalk.

flint.
Cornwall stone.
These ingredients are to be either together or separately reduced to a fine state of
division by grinding or otherwise, and after having been well ground or pulverised
they are to be thoroughly mixed or incorporated together, a sufficient proportion of
water being added thereto to enable the mass to bind or hold together. In this
condition it is moulded under pressure into. bricks, tiles, or other similar articles,
which by the process of burning become completely vitrified, and when cool are
ready for the market.

page_text: The bricks, tiles, or other like articles made from the peculiar compound or com-
position herein-before described may be more or less colored or ornamented by the
addition to the said compound of any of the well-known coloring oxides.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Henry Baggeley in the Great Seal Patent Office on the 9th April
1878.
HENRY BAGGELEY, of the Firm of Baggeley and Green, of Saffron Walden, in the
County of Essex, Manufacturing Chemists. "A NEW OR IMPROVED COMPOUND
OR COMPOSITION FOR THE MANUFACTURE OF BRICKS, TILES, AND OTHER SIMILAR
ARTICLES."
My said Invention relates to a peculiar compound or composition for the manu-
facture of bricks, tiles, and other similar articles, the said articles manufactured
therefrom being more durable, and absolutely impervious to moisture.
According to my Invention I prepare a compound or composition composed of the
following ingredients in or about the proportions herein-after set forth, which pro-
portions I have found to give the best results, that is to say :-
300 parts by weight of chalk.

flint.
Cornwall stone.
These ingredients are to be either together or separately reduced to a fine state of
division by grinding or otherwise, and after having been well ground or pulverised
they are to be thoroughly mixed or incorporated together, a sufficient proportion of
water being then added thereto in order to enable the mass to bind or hold together,
the said mass being in a semi-dry condition, and not soft enough to be pasty or
plastic when introduced into the moulds. In this condition it is moulded under
powerful pressure by hydraulic presses or other suitable and well-known means into
bricks, tiles, and other similar articles, which by a subsequent process of burning
during a period of about 4 days and nights, more or less, according to the draught,
become completely vitrified, after which they are allowed to cool gradually, and on
removal from the kiln are ready for the market.
The bricks, tiles, or other like articles made from the peculiar compound or com-
position herein-before described may be more or less colored or ornamented, as is
well understood, by the addition to the said compound of any of the well-known
coloring oxides.
Having now described, and particularly ascertained the nature of my said Inven-
tion, and the manner in which the same is or may be used or carried into effect, I
would observe in conclusion that what I consider to be novel and original, and
therefore claim as the Invention secured to me by the herein-before in part recited
Letters Patent is,―
First. The peculiar compound or composition for the manufacture of vitrified
bricks, tiles, and other similar artcles, as herein-before described.

page_text: Second. The use of bricks, tiles, and other similar articles manufactured from the
peculiar compound or composition herein-before specified.
In witness whereof, I, the said Henry Baggeley, have hereunto set my hand
and seal, this Eighth day of April, in the year of our Lord One thousand
eight hundred and seventy-eight.
