We, JOHN RIDGWAY, and EDWARD AKROYD RIDGWAY, both of Bedford Works,
Stoke on Trent, Staffordshire, Earthenware Manufacturers, do hereby declare the
nature of the said invention, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
This invention relates to improvements in transfer paper for applying lithographic
impressions to pottery.
The invention consists essentially in coating or treating the paper used for receiving
the lithographic impression and transferring the same to the pottery ware with a
solution prepared by dissolving Irish Moss in boiling water. The solution is
preferably used when of a syrupy consistency, and is evenly applied to the paper
preferably by means of a brush, or it may be applied in any other suitable manner
such as by passing the paper through the solution or by squeezing the solution
through the paper.
When thoroughly dry the paper is highly calendered, and is then ready for receiving
the lithographic impression which is transferred thereto as follows. About equal
quantities of the oils used as the medium for conveying lithographic impressions in
pottery colors and known in the pottery trade as groundlaying and printing oils, are
mixed on a heated slab and the desired color is then added in the required proportion.
After each color is printed on the transfer paper the impression is dusted with the
same color, any slight stain caused by this process being removed by passing a moist
sponge lightly over the print.
The impressions thus obtained are transferred to the ware as follows:-Tho ware is
sized or coated with about equal parts of groundlayers oil and turpentine applied
evenly and thinly with a brush. After drying for a short time the ware is ready for
the transfer. An impression obtained as above is then laid on the ware, moistened
on the back with a damp sponge, and pressed slightly to the ware with the fingers,
after which the transfer paper is carefully pulled up, when the printed design will be
left intact on the surface of the ware. The piece of pottery is then ready for firing
in the usual way.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that
what we claim is :-
1. The coating or treating paper used for receiving lithographic impressions and
transferring the same to pottery, with a solution of Irish Moss, substantially as
herein before described.
2. The application and use of paper coated or treated with a solution of Irish Moss
for receiving lithographic impressions and transferring the same to pottery, sub-
stantially as herein before described.
