IMPROVEMENTS IN
ALBERT WENGER of Hanley in the County of Stafford
THE DECORATION OF CERAMIC WARE AND IN
WHICH IMPROVED MACHINERY MAY BE USED FOR OTHER PURPOSES
THE MACHINERY USED THEREIN
"
This Invention relates more particularly to an improved method or process of.
applying colors or coloring matter to the decoration of articles of ceramic ware in
such a manner as to produce upon the exterior surface, or if desired upon the
exterior and interior surfaces thereof the appearance of being marbled, such
marbling being produced in any tints or colors or combinations of tints or colors
which may be desired
In order to carry out such invention I proceed as follows-I place the article to
be marbled preferably in a suitable vessel containing sufficient water to entirely
cover it
I then sprinkle upon the surface of the water any color or colors of lighter
specific gravity than the water itself after which I stir the color or colors with a
thin strip of wood or other suitable implement in order to disintegrate them and
cause them to expand upon the surface of the water thus producing a pattern-I
then run the water off-(the vessel wherein the article to be decorated is immersed
being provided with a tap for that purpose)-and by so doing the colors floating
on the surface of the water are deposited on the article to be decorated thus
producing the required pattern-The colors are then hardened on by firing in the
usual way

page_text: When it is necessary to use colors or coloring matter possessing greater specific
gravity than water and which would consequently sink therein-I substitute for
the water a preparation of a gelatinous or analogous nature and of a sufficient con-
sistency to support such heavy coloring matters upon its surface-The article to be
decorated is then immersed in this color bath and after so doing any adhering
gelatinous or other equivalent matter is washed off by holding the article under a
stream of water while the color is left adhering to the article
I then fix the pattern in the manner already described-I prepare the colors
which I employ in my improved process of decoration in an improved mixing
machine the construction of which may be briefly described as follows-I fix a
grinding roller at the end of a diagonally placed revolving spindle-The roller I
make preferably pear shaped and I introduce it into and against the sides of an
open top pan or vessel-The colors or other material to be mixed or ground are
then placed in the vessel:-The roller revolves and grinds and mixes them as
required The spindle carrying the roller works through a swivelling frame and
thereby the roller can be raised clear of the vessel for cleaning and emptying The
open top vessel may be heated if required by steam, gas or other suitable means
and is carried upon trunnions whereby when the roller is raised thereout it can be
canted over and the contents emptied This improved machine may also be used
for preparing other materials requiring to be ground or mixed
