A Preservative Composition, applicable also for the Manufacture of
Artificial Stone, Statuary, and the like.
I, AUGUSTIN CLERY of 18 New Compton Street Shaftesbury Avenue in the
County of London, Sculptor, 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:-
My invention relates to improvements in the manufacture of artificial stone and
consists of a liquid and of a powder which are mixed together for the purpose of
being applied to any surface requiring to be provided with a protective damp proof
coating, covering or layer imitating stonework. The same substance is likewise
utilizable for casting and moulding statues, vases, ornaments and other articles or
objects and for repairing stone and marble works, pieces, parts or objects of every
description.
In carrying my invention into practice, I prepare a liquid containing the
following ingredients mixed in the proportions indicated viz.:
The tin is first dissolved in the acid, after which the sal ammoniac is incorporated
in small pieces in the mixture.
I further prepare a powder containing the following ingredients mixed in the
proportions indicated viz.:

Pulverized freestone
Zinc oxide

Powdered marble
Calcined magnesia
The above ingredients are intimately mixed and passed through a fine sieve so as
to form a powder which is reduced to a pasty consistence with the above liquid (1),
this paste being applied with a trowel to the surface (building front, inner or outer
wall) which is to receive a damp proof covering, layer or coating. After a very
short space of time this paste becomes very hard and assumes the appearance of
stone and after being well set it is as hard as flint and has a smooth polished
surface which can be rapidly painted if required in the ordinary way. Or 1
mix any suitable coloring material, dye or pigment with the above powder (2) so
as to impart to the hardened coating either a plain color or a marbled, veined or
motley surface. Although the above proportions for (1) and (2) are the best to
my knowledge, it is obvious that I may slightly alter them without departing from
the nature of my invention.

This covering material is particularly applicable for walls in basements, cellars
and other similar places which are liable to be damp as well as for lining cisterns,
pits and the like, in short it can be used as a damp proof coating under any
circumstances for covering wood, metal &c. as well as stonework, brickwork,
masonry and the like.

page_text: I also use the said material for covering the front, sides, rear or other parts of
buildings so as to imitate stone, while obtaining a damp proof, hard and practically
impenetrable surface.
The above material or paste may be further utilized for repairing and restoring more
or less dilapidated churches, mansions and other buildings, statues, columns, vases
and other ornaments or pieces of stone and marble, and generally for all casting and
moulding purposes for which plaster of Paris is generally used, my improved paste
being manipulated in exactly the same manner as the latter and producing ornaments
of fine appearance having a hard surface and being made to assume when required
by the judicious addition of suitable colors the appearance of marble, granite or
other ornamental stone.
In all cases the paste is only made when required for immediate use.
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 :
1. The new or improved damp proof material for covering or coating wall and
other surfaces, consisting of a paste made by mixing a powder containing pulverized
freestone, zinc oxide, pounded glass, marble and calcined magnesia incorporated in
the proportions herein set forth with a liquid containing muriatic acid, tin and sal
ammoniac mixed in the proportions given substantially as herein described.
2. The new or improved material for repairing stone or marble consisting of a
paste made by mixing a powder containing pulverized freestone, zinc oxide, pounded
glass, marble and calcined magnesia incorporated in the proportions herein set
forth with a liquid containing muriatic acid, tin and sal ammoniac mixed in the
proportions given substantially as herein described.
3. The new or improved material for casting or moulding statues, vases and
ornaments of every description consisting of a paste made by mixing a powder
containing pulverized freestone, zinc oxide, pounded glass, marble and calcined
magnesia, incorporated in the proportions herein set forth with a liquid containing
muriatic acid, tin and sal ammoniac mixed in the proportions given substantially as
herein described.
4. The addition to the material above claimed of suitable coloring matter, dyes
or pigments for the purpose of imitating marble, granite and other artistic or
ornamental stones substantially as herein described.
