LETTERS PATENT to Charles Denton Abel of N° 28 Southampton Buildings
Chancery Lane, in the county of Middlesex. for an Invention of "IMPRove-
MENTS IN DECORATING GLASS ARTICLES, AND SHEET OR PLATE GLASS com-
municated to him from abroad by Arthur Schierholz of Plaue, Thuringia in the
German Empire
PROVISIONAL SPECIFICATION left by the said Charles Denton Abel at
the Office of the Commissioners of Patents on the 17th July 1883.
CHARLES DENTON ABEL of No. 28 Southampton Buildings, Chancery Lane in
the county of Middlesex, "IMPROVEMENTS IN DECORATING GLASS ARTICLES AND
SHEET OR PLATE GLASS [communicated to him from ad by Arthur
Schierholz of Plaue, Thuringia in the German Empire]
According to this invention, ornamental and other articles of glass, whether blown,
cast, or pressed, such as statuettes, vases and the like, as also plate or sheet glass,,
are decorated by first coating the glass with enamel compound of a syrupy
consistency, either colored or transparent, and while this is still sticky, strewing
thereon small glass beads, either solid or perforated, and either colored or not, so
that when the glass is subjected to heat sufficient to melt the enamel, the beads?
will become cemented to the surface of the glass, and thus provide it with a
peculiar refracting vitreous coating that imparts great brilliancy to the colors,"
when sucli are used.
When the glass object has already been painted upon and the colors burnt in, a
colorless transparent enamel compound is employed for the above purpose; it is
preferred, however, to effect the above coating at the same time that the glass is
painted upon with the enamel colors.
In preparing so called "Cathedral Glass" according to this invention, either the.
entire sheet or plate is coated with colored or colorless enamel compound, upon
which the glass beads, either colored or white, are strewn, or the enamel coating is,
only applied to part of the surface, according to any desired design.

CHARLES DENTON ABEL of N° 28 Southampton Buildings, Chancery Lane in
the county of Middlesex "IMPROVEMENTS IN DECORATING GLASS ARTICLES, AND
SHEET OR PLATE GLASS A communication to me from abroad by Arthur
Schierholz, of Plaue, Thuringia in the German Empire
"
· According to this invention, ornamental and other articles of glass, whether
blown, cast or pressed such as statuettes, vases, glass plates, and the like, as also
plate or sheet glass, are decorated by first coating the glass with, ordinary enamel
compound of a sirupy consistency, either colored or transparent, and, while this is
still sticky, strewing thereon small glass beads, either solid or perforated, and
either colored or not, so that, when the glass is subjected to heat in muffle furnaces,
sufficient to melt the enamel, the beads will become cemented to the surface of the
glass, and thus provide it with a peculiar refracting vitreous coating that imparts
great brilliancy to the colors when such are used.
When the glass object has already been painted upon and the colors burnt in, or
when it consists of colored glass or is flashed with colored glass, a colorless trans-
parent enamel compound is employed for the above purpose; it is preferred,
however, to effect the above coating at the same time that the glass is painted
upon with the enamel colors, as, otherwise, greater care is required in painting
with the enamel- colors, and also, a greater expense and risk is entailed by
having first to subject the object to the operation of burning in the enamel colors
and then to a second heating for burning on the above described coating.
Sheet glass or glass plates are prepared in precisely the same manner as above
described, being first painted upon with enamel colors, and then strewn over with
the glass beads, and subjected to heat in suitable muffle furnaces.
In preparing so-called "Cathedral Glass," according to this invention, either the
entire sheet or plate is coated with colored or colorless enamel compound, upon
which the glass beads, either colored or white, are strewn, or the enamel coating is
only applied to part of the surface, according to any desired design.
In preparing glass objects according to the above described invention, it is
preferred to employ solid glass beads, but, for the sake of cheapness, ordinary glass
beads having perforations may be used.
Having thus described the nature of this invention and in what manner the
same is to be performed, as communicated to me by my foreign correspondent;
I claim :-
First The hereindescribed improved manufacture of decorated moulded, blown
or cast glass articles, whereby these are first painted upon with enamel colors, or
with colorless enamel compounds, and while the enamel is still sticky, are then,
strewn over with glass beads, the articles so prepared being lastly subjected to
heat so as to melt the enamel coating and cause the glass beads to be cemented to
the surface of the article thereby.
Second: The hereindescribed improved manufacture of decorated sheet or plate
glass or "Cathedral Glass" consisting in first painting upon the whole or only part

page_text: of the surface of the glass with enamel colors or colorless enamel compounds, and
after strewing upon the surface so prepared small glass beads, subjecting the glass
to heat so as to melt the enamel and thereby cement the glass beads to the surface
In witness whereof I the said Charles Denton Abel have hereunto set my hand
and seal this ninth day of January in the year of our Lord, one thousand, eight
hundred and eighty-three.
