We, HENRY LEWIS DOULTON and WILTON PARKER RIX of Lambeth Pottery,
London, S.E., Potiers, do hereby declare the nature of this invention to be as follows:-
For producing a transfer on pottery we lay a soft etching ground in the ordinary
way upon a copper plate. A piece of lace, or any similar texture, feather, leaf, or
other natural object, is then laid upon the said soft ground. A sheet of ordinary
cardboard is next laid upon the plate, over the lace, feather, or leaves. Then the
whole is laid between the rolls of an ordinary printing press, the pressure of which
drives the lace, feather or leaves through the soft ground, and thereby exposes the
bright face of the copper in the places where the impression is made. The lace or
other object is then removed, and the plate is then put into the acid bath and bitten to
any required depth. The transfer of the impression to the pottery to be decorated is
carried out by the usual method of transfer paper with potters colors, as in pottery
printing.
For tiles, we decorate by laying pottery color upon the tile, and placing the lace,
feathers, leaves, etc., upon the tile, a piece of ordinary cardboard is then laid over
them, and the whole passed under pressure as before; the lace is then removed, and
the tile is fired to vitrify the color, or, after first covering the surface of the tile with
wax, or other varnish, suitable to resisting the acid, we place the lace, leaves, feathers,
etc., on the surface, and by pressure expose the surface of the tile, as before. The
exposed surface is then etched, or bitten by hydrofluoric acid, leaving the design
upon the tile.
In decorating glass, we proceed in the same way as for tiles, either by vitrifying
the color of the background by firing, or by etching by hydrofluoric acid, after
exposing the surface which has been previously covered with a resistant varnish
or wax.

We, HENRY LEWIS DOULTON and WILTON PARKER RIX of Lambeth Pottery,

manner the same is to be performed to be particularly described and ascertained in
and by the following statement:-

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 :-
The improvements in ornamenting pottery tiles or glass substantially as described.
