Improvements in the Manufacture of Dyes, Disinfectants, Artificial
Stone, Artificial Ivory, Artificial Manure, Sodium Chloride, Zino
Sulphate, and Zinc Carbonate.
I, RUSSELL HUGH WORTHINGTON BIGGS of 3 Middle Temple Lane in the City of
London, Barrister-at-Law, do hereby declare the nature of my said invention to be as
follows:
This invention relates to improvements in the manufacture of dyes, disinfectants,
artificial stone, artificial ivory, artificial manure, sodium, and other similar substances,
and consists in utilizing the sub-products arising from the extraction of tin from iron
in tin scraps, consisting of the Chloruret of Zinc and Iron.
The Chloruret of Zinc (ZNCL,) I utilize for disinfecting and preserving wood and
other articles.
By mixing the Chloruret of Zinc (Z N CL₂) with sand or broken glass artificial stone
and ivory are produced, each being determined by the amount or proportions of sand
and broken glass introduced.
The Chloruret of Iron (FE, CL) or (FE, CL.) which naturally remains in the bath
is mixed with Tannate of Iron (FE C27 H₂2 017) which produces the best blue or black
dyes for silk.
22
By the introduction of soda to the sub-products the Chloruret of Zinc falls or
precipitates to the bottom of the vat or cistern; the remaining products forming
Chloride of Sodium or other salts which are employed in the production of artificial
manure, dyes, bleaching powder, and other analogous purposes.

I, RUSSELL HUGH WORTHINGTON BIGGS of 3 Middle Temple Lane in the City of
London, Barrister at Law, do hereby declare the nature of my said 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 improvements in the manufacture of dyes, disinfectants,
artificial stone, artificial ivory, artificial manure, sodium compounds, and other similar
substances, and consists in utilizing the sub-products arising from the extraction of
tin from iron in tin scraps, consisting of the Chloruret of Zinc and Iron.
The Chloruret of Zinc (ZNCL) is reduced to a density of 15 degrees Beaumé for
the purpose of disinfecting and preserving wood and other similar articles.
By mixing the Chloruret of Zinc (Z NCL,) with sand or broken glass artificial
stone and ivory are produced, the amount of sand and broken glass being determined
according to the consistency of the liquid Chloruret of Zinc, each being produced by
the proportions of sand or broken glass introduced.
The Chloruret of Iron (Fe Cl₂) or (FE, CL.) which naturally remains in the bath
is mixed with Tannate of Iron (FE C₂ H₂ 017) which produces the best blue or black
dyes for silk.

To produce solid Chloruret of Zinc for dyeing purposes and as a disinfectant pure
zinc is added until the density is 45 degrees Beaumé, after which it is heated and then
placed in a cooling chamber to form a crystaline mass.
Sulphate of Zine is produced by treating the Chloruret of Zinc with Sulphuric Acid
to displace the Muriatic or Hydrochloric Acid which converts the Chloruret into Sulphate
and which crystalises at an ordinary temperature with 7 equivalents of water, when it
can be utilized for dyeing.
Carbonate of Zinc is produced by mixing Carbonate of Soda, the quantity being
according to the strength of the Chloruret of Zine. The carbon in the soda assimilates
the Zine and forms Carbonate of Zinc, which is indissoluble in water and which
precipitates itself to the bottom of the mixing vat in the form of a white powder, and
the chloride-released by this operation-assimilates with the Sodium and forms
Chloride of Sodium which remains dissolved in the liquid or water in which the Chloride
of Zinc was diluted.
Chloride of Sodium is collected from the water in which it is in dissolution by
evaporation. This salt, thus obtained, can be used in agriculture for the manufacture
of artificial manure, or may be used for the manufacture of Soda and Hydrochloric

page_text: Acid from which dyes and powder for bleaching and other similar purposes can be
produced.
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 —
The manufacture of dyes, disinfectants, artificial stone, artificial ivory, artificial
manure, sodium chloride, zinc sulphate and zinc carbonate from the sub-products
consisting of Chlorurets of Zinc and Iron arising from the extraction of tín from iron
in tin scraps, substantially as described and herein set forth.
