page_text: 1, FRANK KINDER CHEESE, of 19, Beechdale Road, Brixton Hill, in the County
of Surrey, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improved means for preparing the backs of glass
tiles to admit of their being fixed by cement to the surfaces of walls and the
like for internal and external decoration.
Heretofore the backs of glass tiles have been first coated over with a fusible
vitreous paste and all over this sand granules have been sprinkled, the tiles
have then been submitted to heat which fuses the paste and causes the granules
to adhere to the glass. In this way the entire surface of the back of the tile
Las been covered with material to which the cement used for fixing the tiles
to the surface of walls or the like will adhere and consequently when the tiles
are being set they are frequently broken by the expansion or contraction of the
cement used.
According to my invention I attach granules to the back of the glass whilst
at the same time leaving the surface of the glass in the spaces between the
granules entirely uncovered so that at these parts the cement will not adhere to
the glass and so give freedom for the cement to expand or contract without
breaking the glass.
To effect this I form the granules of sand, powdered asbestos or the like and
matters which when exposed to heat will fuse together these substances being
held cemented one with another by gum or the like.
In applying these granules to the back of the glass the surface of the glass
which may be either plain or colored is first damped with clean water and small
pieces or granules of the mixture are sprinkled over it-the gum which they con-
tain then causing them to adhere to the glass each granule being self affixing.
The glass is then fired in a suitable kiln, the fusible materials in the granules
fuse together and the granules become securely attached to the glass.
The granules may advantageously be composed of a mixture of sand, powdered
asbestos, oxide of lead, borax and gum.
The gum should first be dissolved in water and the other materials then
admixed with it to form a stiff dough which hardens when allowed to dry, and
when dry it can be crushed into granules of the required size.
Dated this 2nd day of November 1899.

:
I, FRANK KINDER CHEESE, of 19, Beechdale Road, Brixton Hill, in the County
of Surrey, Engineer, 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:-
This invention relates to improved means for preparing the backs of glass
tilès to admit of their being fixed by cement to the surfaces of walls and the
like for internal and external decoration.
Heretofore the backs of glass tiles have been first coated over with a fusible
vitreous paste and all over this sand or glass granules have been sprinkled, the tiles
have then been submitted to heat which fuses the paste and causes the granules
to adhere to the glass. In this way the entire surface of the back of the tile
has been covered with material to which the cement used for fixing the tiles
to the surface of walls or the like will adhere and consequently when the tiles
are being set they are frequently broken by the expansion or contraction of the
cement used.
According to my invention I attach as hereinafter described small lumps or
granules to the back of the glass whilst at the same time leaving the surface of
the glass in the spaces between the lumps or granules entirely uncovered so that
at these parts the cement will not adhere and so freedom is given for the cement
to expand or contract without breaking the glass.
To effect this in place of using granules of sand or glass as heretofore I form
small lumps or granules of a mixture which is held cemented together by gum
or the like and is composed of sand, powdered asbestos or the like and matters
which when exposed to heat will fuse together.
The lumps or granules may advantageously be composed of a mixture of sand,
powdered or divided asbestos, oxide of lead, borax and gum in the proportion say
of about

page_text: fuse together and the lumps or granules become securely attached to the glass,
the slab with the glass upon it may then be removed from the heat and allowed
to cool slowly.
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:-
a mix-
1. The manufacture of a glass tile with roughened back by moistening the
back dropping on to it small lumps or granules formed from
ture held together by gum or the like and composed of sand asbestos or the like
admixed with other materials which will fuse together and unite with the sur-
face of the glass and then heating the glass in a kiln to fuse the fusible material
in the granules.
2. A glass tile formed with a roughened back substantially in the manner
hereinbefore described.
