PROVISIONAL SPECIFICATION.
A New or Improved Method of Coating Metals with Vitreous Enamel.
I, CHARLES ARTHUR FUGE, of Garscube, Causewayhead, in the County of Stirling,
Enamel Manufacturer, do hereby declare the nature of my invention to be as
follows:-
This invention has reference to and comprises a new or improved method of
coating metals with vitreous enamel by which the method at present followed
will be simplified and rendered more economical, while the danger to the health
of the workpeople from lead poisoning in certain cases will be minimised.
In carrying into practice the improvements of this invention instead of applying
the glass or enamel in a powder to the metal when hot or applying a layer of the
enamel composition to the surface of the metal and afterwards fusing same in a
furnace, the article to be coated is immersed in a bath of the glass, glass enamel,
or like composition while that is in a molten state, or it may be otherwise applied,
as by swilling or putting on the molten glass with a ladle.
When cast or wrought iron articles such as pipes, cisterns, plates, or the like
are to be enamelled they are first cleaned and heated in any convenient form of
furnace or stove. They are then deposited or immersed in a bath of molten glass,
glass enamel, flux, or the like composition, which may be of any of the compositions
in ordinary use for such enamelling purposes, and kept in a molten state in a
vessel of convenient form heated by any ordinary means to the temperature neces-
sary to keep it in a state of fusion. After remaining a short time in this bath
the articles are removed, drained and allowed to cool.
The articles may be immersed in the bath without previous heating but in
this case they require to remain immersed longer than is necessary when heated.
Instead of dipping the articles in a bath the molten enamel may be applied by
pouring it over the hot articles by a ladle or similar means.
In some cases a coating of liquid enamel may be applied to the articles before
heating and the process completed by immersion in the bath.

as by *.
When cast or wrought iron articles such as pipes, cisterns, plates or the like
are to be enamelled they are first cleaned and heated in any convenient form of
furnace or stove. They are then deposited or immersed in a bath of molten glass,
glass enamel, flux, or the like composition, which may be any of the compositions
in ordinary use for enamelling purposes, and kept in a molten state in a
vessel of convenient form heated by any ordinary means to the temperature neces-
sary to keep it in a state of fusion. After remaining a short time in this bath
the articles are removed, drained and allowed to cool.
The articles may be immersed in the bath without previous heating but in
this case they require to remain immersed longer than is necessary when heated.
Instead of dipping the articles in a bath the molten enamel may be applied by
pouring it over the hot articles by a ladle or similar means.
In some cases a coating of liquid enamel may be applied to the articles before
heating and the process completed by immersion in the bath.
Having now 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:-
The improved method of coating. metals with vitreous enamel consisting in
immersing the article in a bath of molten glass, glass enamel, flux or like com-
position or swilling the article with glass enamel or the like, the articles being
preferably previously heated substantially as described.
