PROVISIONAL SPECIFICATION.
Improvements in or relating to Painting or Printing upon
Earthenware.
I, WILLIAM HALES TURNER of Chell Lodge, Tunstall in the County of Stafford,
carthenware manufacturer, do hereby declare the nature of this invention to be as
follows:-
The chief object of this invention is to imitate in machine painting or printing the
effects of the brush which it has not hitherto been possible to do in machine printing
or painting upon china earthenware and the like.
In carrying out my invention which is particularly applicable for monochrome
printing or painting I prefer to produce the design upon the roll or plate by etching
with acid in the well known manner, but instead of completing the process at one or
two operations, 1 prefer to make several operations of it and by this means I am
enabled to produce differences and fineness of shade hitherto unattainable. I
commence by etching the finer portions of shading in the usual manner; then I cover
these with the wax or equivalent acid resisting material and etch again a little deeper
and so on until the desired effect has been obtained.
The process so far will as described produce the various shades required but to
obtain the effect of the brush I brush the acid while upon the metal with a brush
feather or equivalent which I find will produce the fine soft effects of the painter's
brush instead of the sharper effects of the engraver's tool.
Dated this 19th day of December 1888.

COMPLETE SPECIFICATION.
Improvements in or relating to Painting or Printing upon
Earthenware.
1, WILLIAM HALES TURNER, of Chell Lodge, Tunstall in the County of Stafford,
Earthenware manufacturer, 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:-
The chief object of this invention is to imitate in machine painting or printing the
effects of the brush which it has not hitherto been possible to do in machine printing
or painting upon china earthenware and the like.
In carrying out my invention which is particularly applicable for monochrome
printing or painting I prefer to produce the design upon the roll or copper plate
from which the paper prints for transference to the earthenware are printed by
etching with acid in the well known manner, but instead of completing the process at
one or two operations, 1 prefer to make several operations of it and by this means 1.
am enabled to produce differences and fineness of shade hitherto unattainable.
commence by etching the finer portions of shading in the usual manner; then I cover
these with the wax or equivalent acid resisting material and etch again the parts to
produce darker shades a little deeper and so on until the desired effect has been
obtained.
L
The process so far will as described produce the various shudes required but to
obtain the effect of the brush I brush or stipple the acid while upon the metal with a
brush feather or equivalent which I find will produce the fine soft effects of the
painter's brush instead of the sharper effects of the engraver's tooi.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is :-
1. The method of producing varying degrees or depths of shading in rolls or plates
for earthen and analogous ware printing by etching in progressive stages according
to the depth of shade required substantially as specified.
2. The method of obtaining the effect of the painter's brush in etching with acid
upon metal consisting in covering the metal with melted wax or equivalent and
stippling this with a brush feather or equivalent substantially as specified.
3. The method of obtaining the effect of the painter's brush in etching with acid
upon metal consisting in working the acid with a brush or equivalent in or upon the
soft wax substantially as specified.
1. The method of obtaining the effect of the painter's brush in etching with acid
upon metal consisting in working the acid with a brush or equivalent in or upon the
soft wax which has previously been stippled substantially as specified.
.
5. The method of treating the rolls or plates for earthen and analogous ware
printing by brushing the acid while upon the metal for the purpose of producing the
effect of the painter's brush substantially as specified.
Dated this 29th day of May 1889.
