PROVISIONAL SPECIFICATION.
Improvements in the Method of Preparing and Fixing of Gold and
Silver Letters or other Figures upon Glass.
I JOSEPH CHEW, of 92 Bishop Street, in the City of Birmingham, Enameller,
do hereby declare the nature of this invention to be as follows :-
-
This invention relates to improvements in the method of preparing and fixing of
gold and silver letters or other figures upon glass such as is generally used for sign
writing or other similar glass ornamentation.
In carrying out my invention I proceed somewhat thus:-
The metallic gold or silver letters, figures or ornamentation are first painted &c.
upon the glass in the ordinary manner and then muffled as is usual.
Ornamental borders or other additions to such metallic letters &c., consisting of
vitrified glass enamel are then applied and subsequently stoved or muffled. If
desired these borders &c. may be first applied with the metallic letters &c.
following.
I now apply upon the back of the said gold or silver a coat of vitrified glass
enamel which is then burnt on to the gold or silver in a muffle, and thus completely
protects and fixes the said metallic surfaces. Such vitrified glass enamel may of
course be varied in colour as may be desired. This my invention applies equally
to plain surface, or sunken surface or raised surface letters &c.
Dated this 3rd day of May 1894.

these means the metallic letters or other ornamentation is completely protected from
atmospheric damage, and also from wear or injury except of an intentional violent
character.

invention, and in what manner the same is to be performed, I declare that what I
claim is :-
The herein before named improvements in the method of preparing and fixing
of gold and silver letters or other figures upon glass, that is to say, coating such
letters and figures &c. with vitrified glass enamel and stoving or burning the same
thereon as described.
