We, THOMAS FERDINAND WALKER, of 126, Hagley Road, Edgbaston, Birming-
ham, England, and EDWARD MAUDE WALSH and SYDNEY BENSON WALSH, both
of Janvier, Gloucester County, State of New Jersey, United States of America,
all Glass Makers, do hereby declare the nature of this invention to be as follows:
Our invention relates to the manufacture of large articles, as slabs, bricks,
tiles, pillars, plaques, &c. from small pieces of aventurine and consists in melt-
ing in a mold, of the approximate size and configuration of the article desired,
small pieces of aventurine either alone or in connection with pieces of glass of
other kinds. The mold in which the melting is accomplished is placed in a
muffle, kiln, oven or lear, heat is applied and the mass is melted. After cooling
the material is cut and polished in the usual manner.

The Manufacture of Bricks, Slabs, Tiles, Pillars, Plaques, and the like
from Small Pieces of Aventurine.
We, THOMAS FERDINAND WALKER, of 126, Hagley Road, Edgbaston, Birming-
ham, England, and EDWARD MAUDE WALSH and SYDNEY BENSON WALSH, both
of Janvier, Gloucester County, State of New Jersey, one of the Uuited States of
America, all Glass Makers, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and as-
certained in and by the following statement:-
66
Our invention relates to the manufacture of large articles, as slabs, bricks,
Aventurine, commonly called
tiles, pillars, plaques, &c., from aventurine.
gold stone is a glass of an opaque golden-brown color filled with specks or
spangles of a bright gold color. It is made by mixing with the batch of sand
and soda usually used in glass making copper or brass filings which are melted
together in a crucible and cooled. During the cooling the melted mass contracts
and breaks into a number of small pieces, hence aventurine has heretofore been
confined in its use to comparatively small ornamental objects, or to articles of

page_text: jewelry. It has been impossible heretofore to obtain it in pieces of any consider-
able size.
In carrying out our invention we take a mould of any suitable material and of
approximately the size of the article desired and place in it the small pieces of
aventurine, or if other colors of glass are desired, in addition to the aventurine,
in the article to be cast, with pieces of glass of the other desired colors. The
mould is now placed in a muffle, kiln, oven, or lear, and either or both the mould
or oven being luted to prevent access of outside air the mass within the mould is
melted, the several small pieces of the aventurine running together and forming
one compact mass which gradually cooled off and annealed, and finally cut and
polished in the usual manner. No effort is made to conduct the process in vacuo
but outside air should be excluded during the process of melting.
The moulds in which the pieces of aventurine, or aventurine and other glass,
are melted may be of any suitable refractory material, and the oven or muffle
in which this mould is placed in order to melt the glass may be of any suitable
form. During the melting care must be taken to exclude all air or oxygen, if
this be not done, the spangles which give the aventurine its beauty and value.
.will oxydize and the material will be valueless.
Having now particularly described and ascertained the nature of our said in-
vention,, and in what manner the same is to be performed, we declare that what
.we claim is :-
The method of making large pieces of aventurine, which consists in welding
and melting small pieces of the material in a mould within a furnace, muffle,
oven, or lear from which air or oxygen is excluded.
