Birmingham in the County of Warwick Glass Manufacturer for an Invention
of IMPROVEMENTS IN THE MANUFACTURE OF GLASS WARE
PROVISIONAL SPECIFICATION left by the said Lewis John Murray at
the Office of the Commissioners of Patents on the 8th November 1883.
LEWIS JOHN MURRAY of the Soho and Vesta Glass Works Birmingham in the
County of Warwick Glass Manufacturer. "IMPROVEMENTS IN THE MANUFacture
OF GLASS WARE"
A hollow vessel of glass is blown in the usual manner, and for ordinary Articles
I prefer that it be made into what is technically called a cup, which hollow vessel
or cup may be of only one kind of glass, or may consist of two, or more layers,
differing in respect of transparency or opacity, colour, or absence of colour.
On the outer, or inner surface, or, on the outer, and inner surfaces of the said
vessel or cup the desired pattern is produced by removing such parts of the layer,
or layers of Glass, as the intended effect necessitates, by the process, or processes of
cutting, etcbing, engraving, sand blasting, or any other method by which the
desired decoration can be obtained.
This may be termed the first stage of the process.
The decorated vessel or cup is then gradually heated until capable of forming
intimate union with molten Glass, and is lined with Glass in the ordinary manner,
such lining being of any kind of Glass necessary to produce the required effect
and the whole is then worked up into the shape of the article to be made.
In some instances it may be found desirable to use a second cup of transparent
Glass to encase the decorated vessel or cup in such a manner as to preserve and.
increase the brilliancy of effect of the pattern.
After the completion of the first stage of the process it is not absolutely
necessary to line the vessel or cup which may simply be heated to the requisite
point and after being attached to a pontil may be worked into shape in the
usual manner, the surface of the article becoming glazed in the process.
By either of the methods as herein explained very beautiful effects may be
produced by the variations of colour, shade, and opacity, the smooth and glazed
surface nevertheless being retained.

by the said Lewis John Murray in the Patent Office on the 5th May 1884.
LEWIS JOHN MURRAY of the Soho and Vesta Glass Works, Birmingham in the
County of Warwick, Glass Manufacturer. "IMPROVEMENTS IN THE MANUFACTURE
OF GLASSWARE"
The object of the invention is to effect improvements in the manufacture of
Glassware and in carrying out my Invention I proceed as follows:-
A hollow vessel of Glass is blown in the usual manner, and for ordinary articles
I prefer that it be made into what is technically called a cup, which hollow vessel
or cup may be of only one kind of Glass, or may consist of two, or more layers,
differing in respect of transparency or opacity, colour, or absence of colour.
On the outer, or inner surface, or, on the outer, and inner surfaces of the said
vessel or cup the desired pattern is produced by removing such parts of the layer,
or layers of Glass, as the intended effect necessitates, by the process, or processos
of cutting, etching, engraving, sand blasting, or any other method by which the
desired decoration can be obtained.
This may be termed the first stage of the Process.
The decorated vessel or cup is then gradually heated until capable of forming
intimate union with molten glass, and is lined with glass in the ordinary manner,
such lining being of any kind of Glass necessary to produce the required effect
and the whole is then worked up into the shape of the article to be made.
In some instances it may be found desirable to use a second cup of transparent
Glass to encase the decorated vessel or cup in such a manner as to preserve and
increase the brilliancy of effect of the pattern.
After the completion of the first stage of the process it is not absolutely
necessary to line the vessel or cup which may simply be heated to the requisite
point and after being attached to a pontil may be worked into shape in the oșual
manner the surface of the article becoming glazed in the process.
By either of the methods as herein explained very beautiful effects may be
produced by the variations of colour, shade, and opacity, the smooth and glazed
surface nevertheless being retained.
Having thus described and ascertained the nature of my said Invention and the
manner of carrying the same into practical effect I would have it understood that.
what I claim is:-
The improvements in the manufacture of Glassware in the manner and for the
purposes substantially as set forth.
In witness whereof I the said Lewis John Murray have hereunto set my hand
and seal this third day of May in the year of our Lord One thousand eight hundred
and eighty four.
