PROVISIONAL SPECIFICATION.
Improvements in Glazing and Enamelling Bricks and the like, and
Iron or other Metals.
I, MAURICE AHERN of Bounds Green, New Southgate, in the County of
Middlesex, Engineer, do hereby declare the nature of this invention to be as
follows:-
-
My invention relates to a composition of materials and modes of applying such
composition for the purpose of glazing or enamelling bricks and the like, also iron
or other metal.
mix together pulverised arsenic glass and broken or waste ceramic material
along with various proportions of alkaline carbonates and nitrates also small
proportions of tin, lead and bismuth powders. Keducing this mixture to a fine
powder I spread it evenly on the surface of bricks before they are compressed, so
that it is well incorporated with the surface of the bricks, and forms a white glaze
or enamel on them when they are burnt. For applying the composition to iron or
other metal, I prefer first to fuse the mixture, then having granulated it by pouring
the melted mass into water, I reduce it to a fine powder which I make up with
water and preferably with a suitable thickening vehicle such as gum, sugar or the
like to the condition of a paint which I spread over the metal with a brush or
otherwise. On heating the metal so as to fuse the material painted on it, this
forms a glaze or enamel on the surface. When the glaze or enamel is to be
coloured I add to the composition such metallic oxides or salts as will give the
desired tints when baked.

I, MAURICE AHERN of Bounds Green, New Southgate, in the County of

manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :—

condition of a paint which I spread over the metal with a brush or otherwise. On
heating the metal so as to fuse the material painted on it, this forms a glaze or
enamel on the surface. When the glaze or enamel is to be colored I add to the
composition such metallic oxides or salts as will give the desired tints when
baked.
The proportions of the ingredients of the glazing and enamelling compositions
may be varied within certain limits. I find the following proportions suitable to
form the composition for glazing and enamelling bricks. Arsenic glass about
60 parts by weight, broken china about 14 parts, carbonate of potash about 4 parts,
carbonate of soda about 5 parts, lead about 2 parts, tin about 1 part and bismuth
from to part. The same composition is applicable also for enamelling metal,
but, for this purpose, as stated above, it is fined, granulated, pulverised, and made
up with water and gum to the consistence of a paint, along with colouring matter
if desired. The composition for enamelling brick may be treated and applied in
the same manner as that for metal.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
A composition for glazing or enamelling bricks and like articles and metals,
prepared and applied substantially as described.
