PROVISIONAL SPECIFICATION.
Improved Method of and Means for Attaching or Connecting Metal
to Earthenware.
I, JOHN SLATER, of York Terrace, Burslem, in the County of Stafford,
Potter, do hereby declare the nature of my said invention to be as follows:-
My invention consists essentially in applying to earthenware a metallic prepara-
tion suitable for the connection of metal objects or fittings thereto by ordinary
solder, soldering iron and blow pipe. For the purpose of effecting a permanent
connection the metallic preparation must be intimately associated with the
ware, and according to my experiments and research the most successful way of
applying the preparation is to fix it down on to the ware by the aid of the enamel
glaze. Such treatment makes it necessary that a metal of high fusibility should
be employed in order to stand the heat of the "glost oven, or such other heat
as may be necessary to fuse the glaze. Furthermore, it must be of a character or
form that enables it to lie closely against the ware and lend itself to intimate
contact, and present a suitable surface for contact with the metal fitting to be
soldered.
In accordance with my invention I take platinum in (by preference) leaf or foil
form, and either plain or perforated.
To this platinum foil, or to the glazed ware at the point where the preparation
is desired, or at the point where the metal object is to be connected, and imme-
diately before the ware is put into the "glost" oven for fixing the glaze,-I
apply a coating of the following mixture, riz.:- Raw glaze or flux, mixed with a
mucilage of gum arabic and water, or the like. This mixture is painted or
spread on the ware as aforesaid, or on one side of the platinum foil. The
two are then pressed together, or the foil is rubbed down into intimate contact
with the ware, and, by reason of the intervening mixture, caused to adhere in a
temporary manner. The ware is then put into the "glost" oven for firing
the glaze, when the raw glaze or flux aforesaid, between the foil and ware,
immediately becomes fused, and fixes the platinum foil to the ware in a most
tenacious manner, partly by adhesion, and partly by the glaze intersecting or pro-
truding into the perforations, and which said foil owing to its high fusing point is
not affected in the least by the "glost" oven heat.
When removed from the oven the platinum so treated and applied presents the
desired preparation to which any metal object may be soldered without fear of
rupture or disconnection from ordinary strains, the perforations in the platinum
its foil like character, and the interposition of the flux serving to create a most
intimate association with the ware.
By means of the aforesaid preparation, metal outlet or inlet pipes may be
soldered on to earthenware closets, lavatories, wash-basins, and other sanitary goods,
and metal mounts, fittings, handles, spouts may be soldered to table ware, and the

page_text: connection in all cases is of a permanent character and able to withstand more
than ordinary strains.

Improved Method of and Means for Attaching or Connecting Metal
to Earthenware.
I, JOHN SLATER, of York Terrace, Burslem, in the County of Stafford,
Potter, 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 ;-
-
My invention consists in applying to earthenware a metallic preparation as here-
inafter described suitable for the connection of metal objects or fittings thereto by
ordinary solder, soldering iron and blow pipe. For the purpose of effecting a per-
manent connection the metallic preparation must be intimately associated with the
ware, and according to my experiments and research the most successful way of
applying the preparation is to fix it down on to the ware by the aid of an enamel
flux or raw glaze. Such treatment makes it necessary that a metal of high
fusibility should be employed in order to stand the heat if necessary of the "glost"
oven, or such other heat as may be requisite to fuse the raw glaze or flux. Further-
more, it must be of a character or form that enables it to lie closely against the ware
and lend itself to intimate contact, and present a suitable surface for contact with
the metal fitting to be soldered.
In accordance with my invention I take platinum in, by preference leaf or foil
form, and either plain or perforated.
To this platinum foil, or to the glazed ware at the point where the preparation
is desired, or at the point where the metal object is to be connected, and imme-
diately before the ware is put into the "glost "or other oven for fixing the glaze,-I
apply a coating of the following mixture, viz. :-Kaw glaze or flux according to the
heat required, mixed with a mucilage of gum arabic and water, or like adhesive
substance. This mixture is painted or spread on the ware as aforesaid, or on one side
of the platinum foil. The two are then pressed together, or the foil is rubbed down
into intimate contact with the ware, and, by reason of the intervening mixture,
caused to adhere in a temporary manner. The ware is then put into the "glost
or other oven for firing when the aforesaid raw glaze or flux, between the foil and
ware, immediately becomes fused, and fixes the platinum foil to the ware in a most
tenacious manner, partly by adhesion, and partly by the glaze intersecting or pro-
truding into the perforations and said foil owing to its high fusing point is
not affected in the least even by the "glost" oven heat.
"
When removed from the oven the platinum so treated and applied presents the
desired preparation to which any metal object may be soldered without fear of
rupture or disconnection from ordinary strains, the perforations in the platinum,
its foil like character and the interposition of the flux serving to create a most
intimate association with the ware.
By means of the aforesaid preparation metal outlet or inlet pipes may be
soldered on to earthenware closets, lavatories, wash-basins, and other sanitary goods,
and metal mounts, fittings, handles, spouts may be soldered to table ware, and the

page_text: connection in all cases is of a permanent.character and able to withstand more
than ordinary strains.
Having thus particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1: Platinum foil fixed down on to earthenware or vitreous substances by the
means of raw glaze or flux mixed with mucilage and then fired either in a "glost"
oven or enamelling kiln, as and for the purposes set forth.
2: Perforated platinum foil, as and for the purposes set forth.
3: The combination with earthenware of platinum foil fixed thereon with
glaze or flux, and a metal fitting connected to the platinum by direct soldering, as
set forth.
