A Process for Ornamenting Glass, Ceramic Ware, and Metal by
Means of Translucid and Opaque Enamels in Relief.
1, WILLIAM LUTWYCHE 187 Wardour Street W. London Stained Glass Manufacturer
do hereby declare the nature of this invention to be as follows :—
は
A process for ornamenting Glass, Ceramic Ware and metal by means of Translucid
and opaque Enamels in relief applied to the surface of the material and afterwards
fired in muffles.
A Tracing is made with a vitrifiable ink of one or various colors or gold silver or
platina and the translucid Enamel is applied to form the design required and raised
in relief.
When opaque Enamels are used a non-vitrifiable ink may be used which disappears
in firing.
By the use of translucid Enamels in relief the ornamentation on glass is visible on
both sides by day and in artificial light.

WILLIAM LUTWYCHE 187 Wardour Street London W. Stained Glass 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
statement:
A process for ornamenting Glass, Ceramic Ware or Metal by means of translucid
and opaque enamels formed in relief, applied to the surface of the material and
afterwards fired in muffles.
A tracing is made with a vitrefiable or non-vitrefiable tracing ink, of one or various
colors, or gold, silver, or platina, forming the outline of the design desired. The
enamel is then applied as a paste to the surface of the Glass. It is then fired in
muffles. The enamels can be made in any color and vary in their composition
according to the work and effect required. They are of two kinds opaque or
translucid articles or flat surfaces when decorated with the enamels, can be coated with
a film of gold, platina or silver to enchance the effect of the enamels.
When enamels have been once fired they can undergo a process of modelling
or "re-haussing" by means of special vitrefiable colors which treatment at once gives
the modern interpretation of flowers and leaves as a natural effect.
The process of these enamels in relief can not only be applied to flat surfaces but
to any shape or form to which glass or ceramic ware can be applied, whether for
windows, door panels, screens, mirrors or other articles of artistic upholstery, or to
fancy glass ware, viz. Goblets, Bottles, Glasses, Globes, Oriental Lamps, Jowel Cases,
Cups, Plates &c.
For Windows the separate pieces are mounted in lead.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is :
1st. The ornamenting of glass with translucid enamels in relief which is an
absolutely new kind of decorative art, and has never before been employed-or
invented not only renders both sides of the Glass decorative, but, Windows se
ornamented display, a rich effect on which ever side the light plays upon them, for
instance, when viewed from the interior they present a rich and velouté "effeet, the
various colors employed being descernible as in ordinary stained glass work; and
when-seen from the exterior these enamels sustain their natural rich coloring elements
and retain the same effect they exhibed when viewed from the interior, deduction
being made of the difference of light, the first being seen by refracted light and the
last by reflected light.

page_text: 2nd. At night by means of artificial light the effect is the reverse, appearing
translucid from the outside and ornamenting the windows in the interior as opaque
enamels do, with this difference, that by reason of their transluceney, the whole effect
is richer and more harmonious than can be obtained by any other means of
decoration, the non-enamelled-parts of the glass, acts a dark back ground, and if
needed this same ground can be conted with a very thin film of Gold, as stated above,
which although Transparent when put up to light and nearly invisible, acts as a gold
background on the side the enamels receive the light.
3rd. Opaque enamels are employed for the decoration of certain articles for the
reason that these enamels fire at a much lower temperature and consequently the
enamels have a greater relief.
