WILLIAM WEBB BOULTON, of the Firm of Boulton and Mills, of Wordsley, in the
County of Stafford, Glass Manufacturers. "IMPROVEMENTS IN ORNAMENTING
GLASS."
My Invention consists of the improvements herein after described in ornamenting
glass, my said improvements being applicable to the ornamenting of articles made
of glass, such as flower vases, lamp reservoirs, chandelier bodies, and the like, as
well as to the ornamenting of sheets, slabs, or blocks of glass to be used for such
purposes as the same are or may be applicable to.
My improvements consist in covering or partly covering glass, either opaque,
semi-opaque, or transparent, with particles of coloured glass, either opaque, semi-
opaque, or transparent, the said particles being either of one colour or of various
colours, and applied to the surface of the glass to be ornamented while the latter is
in a heated or semi-fused plastic state.
In carrying my Invention into effect I pound or crush opaque, semi-opaque, or
transparent enamels or glasses, and sprinkle the particles so obtained on a slab of
iron or other surface, on which slab of iron or surface I roll or press the hot and
plastic glass to be ornamented, and thereby cause the particles of glass or enamel
to attach themselves firmly to the said glass to be ornamented. The coloured glasses
or enamels crushed to produce the particles described are somewhat more fusible
than the glass to be ornamented, so that while the glass to be ornamented is exposed
to such a heat as gives it the required working qualities, the particles of coloured
ornamenting glass or enamel will be fused so as to cause the colours to spread more
or less upon the surface of the glass under treatment. The glass, after the coloured
particles have been attached thereto, may be covered with a film or thin layer of
flint glass to give a smooth surface to it. The glass so ornamented may have a
rough or cracked appearance given to it by repeatedly plunging it while in a heated
state into water or other liquid. The glass so ornamented may be fashioned by the
processes ordinarily employed in the glass manufacture, that is to say, by moulding,
blowing, pressing, or cutting, or by any combination of these processes.
The opaque or semi-opaque foundation to which the coloured particles are attached
may either be white or coloured, in which case the ornamentation produced consists
of colours displayed on a white or coloured ground; or the foundation may be black,
in which case the ornamenting particles are displayed upon a black ground; or the

The coloured particles may be sprinkled upon the surface from which they are

coloured particles may be arranged-in-stripes or curves, or in any desired
patterns.
When a number of particles of different colours are employed without special
arrangement the glass ornamented has the appearance of variegated or coloured
marbles
