MANDER, Chymist, AARON MANBY, Iron Master, and JOSEPH VERNON,
Furnace Man, all of the Parish of Wolverhampton, in the County of

WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Thirty-first day of May,
in the fifty-third year of His reign, give and grant unto us, the said John
Mander, Aaron Manby, and Joseph Vernon, our exors, adññiors, and assigns,
His especial licence, full power, sole priviledge and authority that we, the
said John Mander, Aaron Manby, and Joseph Vernon, our exors; adiñiors, and
assigns, should and lawfully might, during the term of years therein men-
tioned, make, use, exercise; and vend, within England, Wales, and the
Town of Berwick-upon-Tweed, our Invention of "A METHOD OR METHODS
OF MAKING THE CINDER, SCORIA, SLAGG, OR BY WHATSOEVER NAME THE
REFUSE PRODUCED IN THE SMELTING OR REFINING OF IRON MAY BE CALLED, INTO
FORMS THAT MAY BE USED FOR ANY PURPOSE TO WHICH BRICK, QUARRY, TILE,
SLATE, OR STONE NOW ARE OR MAY BE APPLIED;" in which said Letters
Patent there is contained a proviso that if we, the said John Mander, Aaron
Manby, and Joseph Vernon, or one of us, shall not particularly describe and
ascertain the nature of our said Invention, and in what manner the same
is to be performed, by an instrument in writing under our hands and seals,
or under the hand and seal of one of us, and cause the same to be inrolled
in His Majesty's High Court of Chancery within six calendar months next

page_text: and immediately after the date of the said Letters Patent, that then the said
Letters Patent, and all liberties and advantages whatsoever thereby granted,
shall utterly cease, determine, and become void, as in and by the same
(relation being thereunto had) may more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, we, the said
John Mander, Aaron Manby, and Joseph Vernon, do hereby declare that the
nature of our said Invention or discovery, and the manner in which the same
is to be performed, is as follows, that is to say:-
The nature of it is to make the slagg, cinder, or scoria that is produced in
the smelting of iron ore and in the refining of iron (which is at present of little
or no value but to mend the roads, and is a great expense and inconvenience
to the iron masters) useful and valuable. And the manner in which we
perform it is: We receive the slagg, cinder, or scoria, by whatever name it is
or may be called, that flows from the furnace or furnaces, finery or fineries
used in smelting iron ore and refining iron into moulds (previously heated,
formed suitable to the purpose for which the matter (which we call Patent
Iron Stones) is designed, and then gradually cool them in annealing flues,
ovens, stoves, or chambers, before we take the matter so formed out of the
moulds.
In witness whereof, we, the said John Mander, Aaron Manby, and
Joseph Vernon, have hereunto set our hands and seals, this Fifteenth
day of November, in the year of our Lord One thousand eight
hundred and thirteen.
