PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of certain Bricks, Tiles,
and the like.
I, WILLIAM HALL KEYS, of Lyndon House, West Bromwich, Staffordshire, Oil,
Varnish and Chemical Manufacturer, do hereby declare the nature of this invention
to be as follows:-
-
This invention relates to improvements in the manufacture of bricks, tiles, quar-
ries, pots and other clay made goods, and refers more particularly to the colouring
of such goods by the means or processes hereinafter explained.
My invention consists primarily in applying thereto Chloride of iron or Sul-
phate of iron, and which preferably is obtained in the form of refuse pickling solu-
tion resulting from the usual practice of pickling iron or steel prior to the
galvanizing of the same and which forms either Chloride or Sulphate of iron.
Such solutions are highly impregnated with iron in chemical combination. This
solution is applied by brushing or by immersion &c., to the surface of the clay
article before burning so that in the operation of burning the Hydrochloric or the
Sulphuric acids are liberated leaving the iron in a uniform condition which will
heighten and improve the colour of the brick when burnt.
I may however prepare such solutions in other ways.
In some cases I may prefer to use the solution in mixing or tempering the clay,
in forming the article. For transport purposes I may by evaporation reduce the
said refuse to dryness or near thereto, for convenience of transport, to the scene of
use, and then again dilute it as may be necessary.
I am aware that oxide of iron has been mixed mechanically with water and
applied to these surfaces in a similar manner, but by reason of its mechanical mix-
ture it cannot be so uniformly laid on, as the Chloride or Sulphate of iron can be
and consequently the result is not so good.

Improvements in the Manufacture of certain Bricks, Tiles,
and the like.
I, WILLIAM HALL KEYS, of Lyndon House, West Bromwich, Staffordshire, Oil,
arnish and Chemical Manufacturer, do hereby declare the nature of this inven-

page_text: tion 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 improvements in the manufacture of bricks, tiles, quar-
ries, pots, and other clay made goods, and refers more particularly to the colouring
of such goods by the means or processes hereinafter explained..
My invention consists primarily in applying thereto chloride of iron or sulphate
of iron, and which preferably is obtained in the form of refuse pickling solution
resulting from the usual practice of pickling iron or steel prior to the galvanizing
of the same and which thus forms either chloride or sulphate of iron. Such solu-
tions are highly impregnated with iron in chemical combination. This solution
is applied by brushing or by immersion &c. to the surface of the clay article before
burning so that in the operation of burning, the hydrochloric or the sulphuric
acids are liberated leaving the iron in a uniform condition upon or near the sur-
face of the brick &c., which will heighten and improve the colour of the brick &c.
when burnt.
I may however prepare such solutions in other ways.
In some cases I may prefer to use the solution in mixing or tempering the clay
in forming the article. For transport purposes I may by evaporation reduce the
said refuse to dryness or near thereto, for convenience of transport to the scene of
use, and then again dilute it as may be necessary.
I am aware that oxide of iron has been mixed mechanically with water and
applied to these, surfaces in a similar manner, but by reason of its mechanical mix-
ture it cannot be laid on as the chloride or sulphate of iron can be, and consequently
the result is not so good.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what I
claim is:
-
1. In the manufacture of bricks and other clay made goods the application and
use of the chemical solution of chloride and sulphate of iron as herein described
and set forth.
:
"
2. The use and application of the refuse pickling solution from iron or steel
galvanizing baths as set forth and for the purposes specified.
Dated this 13th day of December 1897.
