WHEREAS His present most Excellent Majesty King George the Third,
by His Letters Patent under the Great Seal of Great Britain, bearing date,at

especial licence, full power,, sole privilege and authority, that I, the said
Matthew Sanderson, my executors, administrators, and assigns, and every of
us, during the term. of years therein expressed, should and lawfully might
make, use, exercise, and vend my new Invention of "PRECIPITATING AND
SMELTING, REPINING AND SEPARATING, METALLIC EARTHS OR CLAYS, AND POOR,
FLINTY, SULPHUREOUS, AND STUBBORN ORES OF LEAD AND COPPER AND SLAGG,"
within that part of Great Britain called England, the Dominion of
Wales, and Town of Berwick-upon-Tweed; in such manner..as to me, my
executors, admors, and assigns, or any of us, should in our discretion
seem; meet; in which said Letters Patent is contained a proviso that if I,
the said Matthew Sanderson, should not particularly describe and ascertain the
nature of my said Invention, and in what manner the same is to be performed,

inrolled in His Majesty's High Court of Chancery within four calendar
months next and immediately after the date of the said Letters Patent,

page_text: NOW KNOW YE, that 1, the said Mathew Sanderson, in pursuance of
and compliance with the said proviso, and the purport and true meaning of the
said Letters Patent, and of His Majesty's said most gracious intentions, do, by
this Instrument in writing under my hand and seal, duly executed, declare that
my said new Invention of Precipitating and Smelting, Refining and Seperating,
Metallic Earths or Clays, and Flinty, Sulphureous, and Stubborn Ores of
Lead and Copper and Slagg, is to be performed in the manner following (that
is to say):
-
Take of the purest vitrescent argilaceous or calearious earthy substance, and
mix therewith a proportionable quantity of perfectly depurated slagg of lead,
saturnine, metallic clays, or cuprous ores, adding thereto the phlogiston or
inflammable principle, by means of which, and a high towering furnace, with
a pipe or chimney adapted thereunto for conveying off the exhaled fume or
smoke, and supplied incessantly with a forcible blast or current of fresh air
by means of two or more large or iron cylindric bellows, the whole may be
put into rapid furious fermentation till the combustible concrete is brought into
a perfect fluid state, or otherwise so regulated as to allow an exhalation or
sublimation of the volatile arsenical and sulphureous quintessence or matter
inherent in and attendent on the metallic ores of Saturn and Venus, agreeable
to the quantity, quality, and necessity thereof. The vitrescent or metallic
particles of the martial earth or ore claiming no union with that of Saturn,
but intimately diffusing themselves through the less ponderous part of the mass,
at the same time absorbing the remaining superabundant sulphur, becomes
of itself a perfect scoria or flux to the other heterogeneous matters adhering,
by means of which fluidity the metallic part of the poor saturnine and cuprous
ores have liberty to precipitate and regenerate into one regular fluid regulus,
at the bottom, which may from time to time be let off and run into any form
required.
In witness whereof, I, the said Matthew Sanderson, have hereunto
sett my hand and seal, this Ninth day of August, in the fourteenth
year of the reign of our Sovereign Lord George the Third, by the
grace of God of Great Britain, France, and Ireland King, Defender
of the Faith, and so forth, and in the year of our Lord One
thousand seven hundred and seventy-four.

page_text: AND BE IT REMEMBRED, that on the same Ninth day of August, in
the year last above mentioned, the aforesaid Matthew Sanderson came
before our said Lord the King in His Chancery, and acknowledged the
Specification of his Invention aforesaid, and all and every thing therein con
tained and specified, in form above written. And also the Specification
aforesaid was stampt according to the tenor of the Statute made in the sixth
year of the reign of the late King and Queen William and Mary of England

TO ALL TO WHOM THESE PRESENTS SHALL COME, greeting.
WHEREAS His presentimost Excellent Majesty King George the Third,
by His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Twenty-seventh day of October, in the fifteenth year of His
reign, did give and grant unto me, MATHEW SANDERSON, of Masbrough, in
the Parish of Rotheram and County of York, Chymist and Refiner, his
especial licence, full power, sole priviledge and authority, that I, the said
Mathew Sanderson, my executors, adiñors, and assigns, and every of us,
during the term of years therein expressed, should and lawfully might make,
use, exercise, and vend my new Invention of "PRECIPITATING AND SMELTING,
REFINING & SEPERATING, METALLIC EARTHS AND CLAYS, AND POOR, FLINTY,
SULPHUREOUS, AND STUBBORN ORES OF LEAD AND COPPER AND SLAGG," within that
part of the Kingdom of Great Britain called England, the Dominion of Wales,
and the Town of Berwick-upon-Tweed, in such manner as to me, my executors,
administrators, and assigns, or any of us, should in our discretion seem meet;
in which said Letters Patent is contained a proviso that if I, the said Mathew
Sanderson, should not particularly describe and ascertain the nature of my said
Invention, and in what manner the same is to be performed, by an instrument
in writing under my hand and seal, and cause the same to be inrolled in
His Majesty's High Court of Chancery within four calendar months next
and immediately after the date of the said Letters Patent, that then the
same Letters Patent, and all liberties and advantages whatsoever thereby
granted, should utterly cease, determine, and become void, as in and by the
said Letters Patent more at large doth appear.
NOW KNOW YE, that I, the said Matthew Sanderson, in pursuance of
and compliance with the said proviso, and the purport and true meaning of the
said Letters Patent, and of His Majesty's said most gracious intentions, do
by this Instrument in writing under my hand and seal, duly executed, declare
that my said new Invention of Precipitating and Smelting, Refining and
Seperating, of Metallic Earths or Clays, and Sulphureous and Refractory Ore
of Lead and Copper and Slagg, is to be performed in the following manner :-
Take of any pure vitrescent argilaceous earthy substance, mix therewith
a proportionable quantity of depurated slagg of lead, saturnine metallic clays
or cuprous ores, adding thereto the phlogiston or inflammable principle, b

incessantly with a forcible blast or current of fresh air by means of two or more
large or iron cylindric bellows, the whole may be put into a rapid intestine
motion till the combustible concrete is brought into a perfect fluid state, and a
compleat separation of the metallic part, at the same time so ordered as to
permit a discharge, exhalation, or sublimation of the volatile arsenical sul-
phureous vapour, gas, or matter inherent and attendant on the metallic ores of
Saturn and Venus, agreeable to quality, quantity, and necessity thereof. The
revivifying particles of the martial earth claiming no union with that of Saturn,
but intimately diffusing itself through the less ponderous part of the mass, at
the same time absorbing the remaining superabundant sulphur, becomes of
itself a perfect scoria or flux to the other heterogeneous matters adhering; by
means of which fluidity the metallic parts of the saturnine and cuprous ores
have liberty to precipitate and regenerate into one regular fluid regulus, at the
bottom, which may from time to time be let off and run into any form required.
In witness whereof, I, the said Matthew Sanderson, have hereunto set
my hand and seal, this Eleventh day of February, in the fifteenth year
of the reign of our Sovereign Lord George the Third, by the grace of
God of Great Britain, France, and Ireland King, Defender of the
Faith, and so forth, and in the year of our Lord One thousand seven
hundred and seventy-five.
