PROVISIONAL SPECIFICATION.
An Improvement in the Method of Etching or Ornamenting Glass.
EDWARD JOHN SHAW, Astral Works, Hatherton Street, Walsall, Lamp and Glass
Manufacturer, do hereby declare the nature of this invention to be as follows :-
:-
A glass globe, or other article, is made of ordinary clear crystal glass, which glass,
however, has a thin coating on the inside surface of ruby glass-the article is then
technically called, a ruby globe (or other article) cased inside. My invention is as
follows; I etch with acid, say, roses and leaves, on the outside of the globe in the
ordinary manner, but on the inside (or ruby coated side of the glass) I eat away
(with acid) the whole coating of thin ruby glass excepting those parts which my
designs may require left ruby glass. For instance; the roses, by my process, would
appear ruby but the remaining part of the globe would be etched crystal glass. My
invention applies to any colour.

page_text: I, EDWARD JOHN SHAW, of Astral Works, Hatherton Street, Walsall, Lamp
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 stateinent :—
This invention relates to an improvement in the method of etching or ornamenting
glass whereby the ruby, green, or other colour on one surface of an article of glass is
utilized in the completion of any design or pattern etched on the other surface.
I will take for example a glass globe made of ordinary clear crystal glass but having
a thin coating of ruby colored glass on its inner surface, technically called a ruby
globe cased inside.
I first etch, with acid, on the outside of the globe say roses and leaves, and I then
cat away with acid the whole coating of thin ruby glass on the inside of the globe
with the exception of such parts as I may require left for giving colour to the roses
of my design; or, assuming the inner coating to be green I may preserve only such
parts of the green as will give colour to leaves etched on the opposite surface, the
remainder of the design remaining white; in short, the coating or casing may be
of any desired colour and of more than one colour if desired, (that is two blended)
and as much of this colour will be removed by acid as may be required to complete
or give colour on the design etched on the opposite or outer surface.
The etching and removal of the colour may be effected by any of the methods now
known and in use. If I desire I may coat the outside of my globe with thin ruby
or other colour-i.e. reverse my process.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
A method of ornamenting articles of glass having one colored surface, consisting
in etching a design, or pattern, upon the non coloured surface and removing the
coloured surface as may be desired to correspond with said etching, substantially as
described.
