THE ART OR MYSTERY OF REPINING COPPER FOR MAKING BRASS BY WROUGHT IRON, AND OF MAKING BRASS BY A MINERAL CALLED BLACK JACK OR BRAZIL, INSTEAD OF CALAMY OR LAPIS CALAMINARIS, AND FOR MANUFACTURING BRASS INTO BRASS WIRE BY STONE OR PIT COAL INSTEAD OF WOOD NOW USED

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
CHAMPION, of the City of Bristol, Merchant, send greeting.
WHEREAS I, the said William Champion, did, by Petition to His
present Majesty, humbly shew that I had, by great study, application, and
expences in trying experiments, found out and discovered and brought to per-
fection "THE ART OR MYSTERY OF REPINING COPPER FOR MAKING BRASS BY
WROUGHT IRON, AND OF MAKING BRASS BY A MINERAL CALLED BLACK JACK OR
BRAZIL, INSTEAD OF CALAMY OR LAPIS CALAMINARIS, AND FOR MANUFACTURING BRASS
INTO BRASS WIRE BY STONE OR PIT COAL INSTEAD OF WOOD NOW USED," and did
therefore pray His said Majesty to grant unto me, the said William
Champion, my exors, adiiors, and assigns, His Royal Letters Patent for
the sole use, benefit, and advantage of the said Invention within that
part of Great Britain called England, the Dominion of Wales, and Town
of Berwick-upon-Tweed; and whereas His most Excellent Majesty King
George the Third, by His Royal Letters Patent under the Great Seal
of Great Britain, bearing date on or about the Twenty-sixth day of January,
in the year of our Lord One thousand seven hundred and sixty-seven, did
give and grant unto me, the said William Champion, His especial licence,
full power, sole priviledge and authority, that I, the said William Champion,
my exors, adiñors, and assigns, or either of them, my or either of their deputy
or deputies, servants or agents, or any other whomsoever I, the said William
Champion, should at any time licence, should and lawfully might make, use,
exercise, and vend the said Invention, within that part of Great Britain called
England, the Dominion of Wales, and Town of Berwick-upon-Tweed, for the
term of fourteen years from the day of the date of the said Letters Patent.

page_text: NOW KNOW YE, that I, the said William Champion, in compliance with
and performance of a proviso or condition contained in the said Letters
Patent, do hereby describe and ascertain the nature of my said Invention to
be as follows, vi z :-
By refining of copper for making of brass with wrought iron intermixed
or thrown into the copper, which when put in fusion causes an extraction of
that pernicious arsenical quality in the copper so hurtful to brass; the sub-
stitution of a mineral called black jack or brazil, instead of calamy or lapis
calaminaris making better brass at a less expence, calamy growing very
scarce; the manufacturing brass into brass wire, by the use of stone or pit
coal instead of wood, more beneficial to that manufactory. And I, the said
William Champion, do hereby aver and declare, that the above is a full, true,
and perfect description of my said Invention, which I am fully purswaded will
be of great benefit to the publick, and a great saving to the nation in
general.
In witness whereof, I, the said William Champion, have hereunto set
my hand and seal, this Twenty-first day of April, in the seventh 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 sixty-seven.
