COMPLETE SPECIFICATION (AMENDED).
An Improved Method of Operating Upon and Decorating Glass,
Earthenware, and Glazed or Enamelled Metallic Substances, and
Appliances connected therewith.
I, JAMES TYRRELL NEWELL, of 184, Warham Street, Kennington Park, Surrey,
Lithographic Printer, 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 :-
This invention relates to a certain method of operating upon glass and earthen-
ware, also glazed or enamelled metallic articles in colour or colours for the
preparation of tablets to indicate the qualities of goods, prices of same, and
generally for decorative purposes, such as with tiles or slabs.
The invention may be described as follows:-I take a strip of opaque, clear, or
coloured glass, and having prepared suitable colour or colours upon a slab to an
even consistency, by means of the base hereinafter described I by means of a soft
roller composed of equal parts of treacle and glue, transfer the colour or colours to
the glass, having first partially covered the same with a stencil plate or plates with
chamfered edges to produce sharpness of outline to the letters, devices, or the like
with which the stencil plate or plates are prepared, these with the glass being
preferably arranged in a frame for the required proper positious and register.
In some cases, I roll more than one colour at the time on the glass by arranging
the colours ou a slab, either to register or to blend for ornamental effect, and then
I pass the glass into a kilu or oven of any suitable kind with a top heat to cause the
colour to amalgamate and become one with the glass, the heat being so governed
that the surface of the glass is not blistered, or the depth of colour reduced.
The colour or colours used for the purpose of my invention are of the well known
kinds employed for decorating glass or ceramic ware, and the colour, or if desired a
varnish composed of about equal proportions of salad oil and rosin may be applied
so that the printing can have powdered metallic bodies dusted on, or leaf gold can
be applied, if desired.
I use the compound of salad oil and rosin as the base for all my printing whether
with colour or not, as I find that during the firing process the tone or tint of colour
however faiul or doop it may be is not interfered with.
The stencil plate or plates may have their usual stops dispensed with, the lottors,
numerals, or other devices being then without breaks in their formation, but should
stops be present the spaces left on the glass or other article can be filled up by
hand.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I wish it to be understood
that it is an essential feature of my improved method that the base for the printing
be composed of salad oil and rosin as hereinbefore set out, and I declare that what
I claim is
1. The improved method herein before described of operating upon and decorating
glass, earthenware, glazed or enamelled metallic surfaces, by the means and
appliances set forth, subject to the disclaiming clause.
2. The appliances, viz., chamfered edged stencil plates, soft rollers of compound
treacle and glue, fraines for holding the bodies to be decorated or printed on by the
method described and in which a mixture of salad oil and rosin forms the base of
my printing media, as described for the purpose set forth.
