Improvements in the Manufacture of Pottery Tissue Paper for
Transfer Printing.
We, THOMAS PHOENIX of Liverpool Road, Newcastle, Staffordshire, Paper Maker,
and GEORGE KIRK (Administrator of the personal estate and effects of Mary Ann
Lamb Widow, Paper Manufacturer, deceased) of Uttoxeter in the same County,
Gentleman, do hereby declare the nature of this invention to be as follows:--
Heretofore pottery tissue paper for transfer printing has been sized by the printer
in sheets after manufacture.
The object of this invention is to produce sized transfer paper in the roll, so that
it can be printed on a cylinder machine from the roll instead of on copper plates in
separate sheets as has hitherto been universal. Transfer paper cannot be sized in
the roll after manufacture on account of its want of substance, which renders it
liable to be torn. Attempts to size it in the process of manufacture have failed
because the materials used for bleaching have affected the size and altered its
nature, thereby producing an unsatisfactory result.
According to this invention the pulp is bleached, then the bleaching agent, usually
bleaching powder is neutralized or killed and the size is added to the pulp and the
manufacture completed.

Improvements in the Manufacture of Pottery Tissue Paper for
Transfer Printing.
We, THOMAS PHOENIX of Liverpool Road Newcastle, Staffordshire, Paper Maker,
and GEORGE KIRK (Administrator of the personal estate and effects of Mary Ann
Lamb, Widow, Paper Manufacturer, deceased) of Uttoxeter in the same County,
Gentleman 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 :---
Heretofore pottery tissue paper for transfer printing has been sized by the printer
in sheets after manufacture.
The object of this invention is to produce sized transfer paper in the roll, so that it
can be printed on a cylinder machine from the roll instead of on copper plates in
separate sheets as has hitherto been universal. Transfer paper cannot be sized in the
roll after manufacture on account of its want of substance, which renders it liable to
be torn. Attempts to size it in the process of manufacture have failed because the
materials used for bleaching have affected the size and altered its nature, thereby
producing an unsatisfactory result.
According to this invention the pulp is bleached, then the bleaching agent, usually
bleaching powder is neutralized or killed and the size is added to the pulp and the
manufacture completed.
The process of manufacture is as follows:-The rope after being shredded is boiled
and reduced into strands, it is then washed and afterwards bleached by bleaching
powder. It then goes through a further washing to clear it of the bleach. Sodium
Hyposulphite is then put into the rag engine and afterwards the size (soft soap and
soda) is added. The sodium hyposulphite is put into the engine an hour or an hour
and a half before the size.
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 :-
1. In the manufacture of pottery tissue paper for transfer printing neutralizing the
agent used for bleaching the pulp and then adding size substantially as described.
2. Our improvements in the manufacture of pottery tissue paper for transfer
printing substantially as described.
