page_text: PROVISIONAL SPECIFICATION.
I Sir SEYMOUR JOHN BLANE of 34 Duke Street St: James's London, Baronet
do hereby declare the nature of my invention for "IMPROVEMENTS IN THE
TREATMENT OF A DIATOMACEOUS EARTH OTHERWISE OR SOMETIMES CALLED
"KIESELGUBR" AND FURNACE SLAG, FOR THE PRODUCTION OF A MATERIAL,
APPLICABLE FOR RENDERING PAINTS, VARNISHES, AND OTHER SUBSTANCES, TO FIRE,
DAMP AND WEATHER PROOF," to be as follows:-
My present invention is an improvement upon the process described by me in
the Specification filed in pursuance of Letters Patent granted to me in the year
1883 N° 1432, and consists in subjecting the "White Peat" in its natural state to
a heat so intense that it is reduced to a very fine powder, instead of simply
calcining it, and taking it from the furnace in soft lumps, and then reducing it to
powder by mechanical means, and "sifting" it as described in the hereinbefore
referred to Specification.
In order to more effectually combine the powder, produced as above described,
with Furnace Slag, than is possible by simply mixing powdered slag with the
white peat powder, I first pulverize the slag, and then place the same into a vat,
or receptacle, containing a suitable quantity of Hydrochloric, or other suitable acid.
Steam is then injected into the vat, or receptacle, containing the pulverized slag
and acid, until the slag and acid are of the consistency of a jelly. When of the
proper consistency this "jellified mass is strained through a canvas, or other
suitable, strainer so as to free the alag jelly from the superfluous acid.
""
The slag jelly is then thoroughly washed whilst in the strainer, so as to free it
entirely from the acid, by means of numerous fine jets of water being played upon
it, from a high pressure water-pipe with a rose attached, or other suitable means.
This slag jelly is then thoroughly incorporated, or combined, with the "White
Peat" powder above mentioned in suitable proportions, with the addition of a
suitable quantity of Lime Water and gum, or a solution of glue, or both, or any
other material suitable for obtaining adhesion and cohesion.
By the combination of the above described ingredients I produce an agent or
material which, when added to paints, varnishes, or other chemicals or materials not
containing oil, will render the same fireproof, and impervious to moisture, and other
atmospheric influences.

wise, or sometimes, called "Kiesulguhr") and Furnace Slag
for the Production of a Motorial Annlicable for Rendering
I Sir SEYMOUR JOHN BLANE of 84 Duke St: St. James' London Bart. do
hereby declare the nature of my invention for IMPROVEMENTS IN THE TREATMENT
OF A DIATOMACEOUS EARTH (OTHERWISE OR SOMETIMES CALLED KIESULGUHR) &
FURNACE SLAG FOR THE PRODUCTION OF A MATERIAL APPLICABLE FOR RENDERING
PAINTS VARNISHES & OTHER SUBSTANCES FIRE DAMP & WEATHER PROOF and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
My present invention is an improvement upon the process described by me in
the Specification filed in pursuance of Letters Patent granted to me in the year
1883 No 1432 and consists in subjecting the "White Peat" in its natural state to
a heat so intense that it is easily reduced to a very fine powder instead of simply
calcining it, and taking it from the furnace in soft lumps and then reducing it to
powder by mechanical means, & "sifting it as described in the herein before referred
to specification,
According to the present invention the white peat (or Kieselgühr) is placed in its
natural state in suitable sized lumps into a furnace or kiln, over lighted coke
charcoal or other suitable fuel.
When the lumps of white peat (Kiesulguhr) contained in the Furnace have
become of a uniform colour (nearly white) they are removed from the furnace and
then reduced to powder by hand pressure.
In order to more effectually combine the powder, produced as above described,
with Furnace Slag, than is possible by simply mixing powdered slag with the
white peat powder (Kiesulguhr) as mentioned in my said former Specification, I
first pulverize the slag and then place the same into a vat or receptacle containing
a suitable quantity of hydrochloric, or other suitable acid. Steam is then injected
into the vat or receptacle containing the pulverized slag and acid, until the slag and
acid are of the consistency of a jelly.
When of the proper consistency this jellified mass is strained through a canvas
or other suitable strainer so as to free the slag jelly from the superfluous acid. The
slag jelly is then thoroughly washed whilst in the strainer, so as to free it entirely
from the acid, by means of numerous fine jets of water being played upon it, from
a high pressure water pipe with a rose attached or other suitable means.
This slag jelly is then thoroughly incorporated or combined with the white peat
(Kiesulguhr) powder above mentioned, in suitable proportions with the addition of
a suitable quantity of lime water and gum, or a solution of glue or both, or any
other material suitable for obtaining adhesion and cohesion.
By the combination of the above described ingredients I produce an agent, or
material, which when added to paints, varnishes, or other chemicals or materials not

page_text: containing oil, will render the same fireproof and impervious to moisture and other
atmospheric influences.
The following are the proportions of the ingredients of a paint suitable for
ordinary protecting purposes viz:-
In making the above paint, the slag jelly and zinc oxide are first mixed together,
the peat powder (Kieselguhr) and Lime Water are next added, and finally the
silicate of soda-the whole being well mixed.
I do not confine myself to the above mentioned proportions, as it is obvious that
for extraordinary purposes it may be necessary to vary the proportions of any or all
of the ingredients.
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
"
1. Subjecting White Peat" (sometimes or otherwise called "Kiesulguhr") to a
beat sufficiently intense to enable the same to be reduced to a fine powder by hand
pressure, substantially as herein described.
2. Rendering furnace slag soft or jellified by the method and means substantially
as herein described.
3. The combination of White Peat (Kiesulguhr) powder with Furnace Slag
"jelly," to which is added the other ingredients substantially as and for the
purposes herein specified.
