BRICKS."
The Invention consists,-
Firstly. In the printing of colours and patterns upon the glazed surfaces of
glazed bricks.
And, Secondly. In the use of enamelled colours (as distinct from "biscuit"
colours) for producing the same.
We carry our Invention into effect in the following manner :- -Copper or other
plates on which the desired pattern is cut or engraved are covered with the
enamelled colour. When the said patterns have been well and properly filled with
the colouring matter, the surplus colour is taken away and a sheet of thin paper
placed over the pattern, when together they are passed through the rollers of a
printing machine. The colour or pattern is then fixed upon or transferred to the
sheet of paper, which sheet is taken away and transferred to the glazed surfaces of
the brick, and the paper is washed or drawn off leaving the colouring material on
the brick.
The bricks are then passed forward to the kiln and fired to a good red
heat.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by the

Firstly. In the printing of colours and patterns upon the glazed surfaces of
glazed bricks.
And, Secondly. In the use of enamel colours (as distinct from "biscuit" colours)
for producing the same.
We carry our Invention into effect in the following manner-Copper or other
plates on which the desired pattern is cut or engraved are covered with the enamel
colour. When the said patterns have been well and properly filled with the
colouring matter, the surplus colour is taken away in the ordinary manner, and a
sheet of thin paper is placed over the pattern, when together they are passed
through the rollers of a printing machine. of any suitable or well known con-
struction. The colour or pattern is then fixed upon or transferred to the sheet of
paper, which sheet of paper is taken away or removed from the engraved plate
and transferred to the glazed surfaces of the brick, and the paper is washed or
drawn off the brick, leaving the colouring material on the brick. The bricks are
then passed forward to the kiln and fired to a good red heat.
We wish it clearly to be understood that we do not claim as new or as our
Invention, the use of a printing press for printing designs to be used in the
ornamentation of pottery for this has been previously used for other purposes,
but not as herein described as applied to glazed bricks; nor do we claim the use
of enamel colours, for they have been in use for painting and ornamenting by
hand on other glazed surfaces; but what we do claim is the combined use of the
printing press and of enamel colours as applied to the ornamentation of the
glazed surfaces of glazed bricks, in mauner substantially as herein described.
In witness whereof, we, the said William Dewhirst Cliff and Walter Cliff, have
hereunto set our hands and seals, this Thirty-first day of July, in the year
of our Lord One thousand eight hundred and seventy-six.
