Improvements in the Manufacture of Pottery or Earthenware.
We THE WORCESTER ROYAL PORCELAIN COMPANY (LIMITED) of the
Royal Porcelain Works, in the City of Worcester, EDWARD PROBERT EVANS,
of Sunnyside, Worcester aforesaid, a Managing Director of the said Company,
ALFRED RUSHTON, of No. 90 Sidbury, in the said City, Foreman of Potters, in the
employ of the said Company, and HENRY HAWKER of Diglis, in the said City,
Foreman of Printers, and also in the employ of the said Company, do hereby
declare the nature of this invention to be as follows :-
This invention is designed to simplify, expedite and cheapen the manufacture of
decorated or ornamented pottery or earthenware.
In carrying out this invention we print in "raised colors" which have been mixed
in the ordinary way for printing on ware, on to the surfaces of clay or like models,
or onto the plaster of Paris, or like "humps," blocks, or moulds or other equivalent
surfaces, the desired pattern which has been obtained from the design engraved
upon copper, or other material. These applied colors or designs may be further
raised or thickened by further applications care being taken to scrupulously preserve
the "register" correctly.
From the printed "humps," blocks, moulds or models, other moulds in reverse
are produced in plastic material-whereon the pattern inverted projections on the
former being here represented by depressions and vice versa. From these, inverted
patterned moulds the ware is produced upon which " ware the pattern
becomes re-inverted and now represents the original form of the printed design in a
raised pattern, which is ready for after treatment or "firing."
66
"
By these means we are enabled to dispense with the old method of applying the
design to the "humps" by means of hand form or modelled pieces of clay to give
the necessary impress of the design in the mould, and to produce by one direct
process patterns of great delicacy and intricacy, much more finely and well defined
than by the ordinary process of modelling in clay; with greater expedition and
economy.

In carrying out this invention we print in "raised colour"
"relief paste,"
which has been mixed in the ordinary way for printing on ware on to the surfaces
of clay or like models, or onto the plaster of Paris, or like, "humps," blocks or
moulds or other equivalent surfaces, the desired pattern which has been obtained
from the design engraved upon copper, or other material.

This applied "raised colour" or "relief paste” design may be further raised or
thickened, by further applications, care being taken to scrupulously preserve the
register" correctly. From the printed "humps" blocks moulds or models, other
moulds in reverse are produced in plastic material whereon the pattern is inverted-
projections on the former being here represented by depressions, and vice versa.
From these inverted patterned moulds the ware is produced upon which " ware
the pattern becomes re-inverted and now represents the original form of the printed
design in a raised pattern which is ready for after treatment or "firing."

the necessary impress of the design in the mould, and to produce by one direct
process patterns of great delicacy and intricacy, much more finely and well defined
than by the ordinary process of modelling in clay; with greater expedition and

Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
in
The method of manufacturing decorated or ornamented pottery or earthenware
by printing the desired pattern to the required height from the engraved surface
raised colour

"relief paste
or
on the model, "hump," block, mould or other
equivalent surface and therefrom producing in plastic material in reverse moulds
and with the aid of these moulds-with pattern in reverse-producing on the ware-
in original relation-the printed pattern in raised design ready for after treatment
or "firing," substantially as described.
