THOMAS DELAVAL, of Seaton Delaval, in the County of Northumberland,
Esquire, send greeting.
WHEREAS I, the said Thomas Delaval, did, by my petition, humbly
represent unto His present most Excellent Majesty King George the
Third, that had by my great study and application discovered "A
CERTAIN COMPOSITION OR FLUX FOR THE MAKING OF GLASS, CONSISTING OF
ASHES, SEA WATER, COPERAS, AND OTHER INGREDIENTS NEVER BEFORE MADE
USE OF FOR THE LIKE PURPOSE; AND THAT I HAD ALSO DISCOVERED THE MEANS
OF MAKING GUNPOWDER FROM SULPHUR STONES, COMMONLY CALLED BRASSES,
FOUND IN COAL MINES, AND OTHER INGREDIENTS NEVER BEFORE MADE USE OF
FOR THAT PURPOSE, AND THOSE WITHOUT THE USE OF CHARCOAL," which ‹lis-
coveries would be of great utility to the public, both in the improve-
ment and reduction of the prices thereof respectively; and therefore
most humbly prayed His said Majesty that he would be graciously
pleased to grant unto me, my executors, administrators, and assigns,
His Royal Letters Patent, for the sole use and benefit of the said
Discoveries or Inventions, within that part of His Kingdom of Great

page_text: Britain called England, His Dominion of Wales, and Town of Berwick
upon Tweed, and IIis Plantations in America, for the term of fourteen
years, pursuant to the Statute in that case made and provided; and
His said Majesty, being willing to give encouragement to all Arts and
Inventions which might be for the publick good, was graciously pleased
to condescend to my request, did, therefore, by His Royal Letters
Patent, bearing date at Westminster, the Twenty-second day of April
now last past, of His special grace, certain knowledge, and meer motion,
for Himself, His heirs and successors, give and grant unto me, the said
Thomas Delaval, my executors, administrators, and assigns, His special
license, full power, sole priviledge and authority, that I, the said Thomas
Delaval, my executors, administrators, and assigns, and every of us, by
myself and ourselves, or by mine and our deputy or deputies, servants
or agents, or such others as I, the said Thomas Delaval, my executors,

from time to time and at all times thereafter, during the term of years
therein expressed, should and lawfully might make, use, exercise and
vend my said Inventions respectively, within that part of His Kingdom
of Great Britain called England, His Dominion of Wales, and Town of
Berwick upon Tweed, and also in Ilis Plantations abroad, in such
manner as to me, the said Thomas Delaval, my executors, adminis-
trators, and assigns, or any of us, should in our discretions seem nicet;
and that I, the said Thomas Delaval, my executors, administrators,
and assigns, should and lawfully might have and enjoy the whole profit,
benefit, commodity, and advantage from time to time coming, growing,
accruing, and arising by reason of the said Inventions respectively, for
and during the term of years therein mentioned, to have, hold, exercise,
and enjoy the said licence, powers, priviledges, and advantages in and by
the said Letters Patent granted, or mentioned to be granted, unto me,

date of the said Letters Patent next and immediately ensuing, and
fully to be compleat and ended, according to the Statute in such case
made and provided; in which said Letters Patent is contained a proviso,
that if I, the said Thomas Delaval, should not particularly describe and

page_text: ascertain the nature of my Inventions, and in what manner the same
are 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 said Letters Patent, and
all liberties and advantages whatsoever thereby granted, should utterly
cease, determine, and become void, anything therein contained to the
contrary thereof in any wise notwithstanding.
NOW KNOW YE, that I, the said Thomas Delaval, in compliance
with the said proviso, do hereby describe and ascertain the nature of
my said Inventions, and in what manner the same are to be performed,
as follows (that is to say):
As for touching and concerning the ingredients for the flux for
making glass, the same are ashes, coperas, soot, arsnick, animal dung,
and salt water, all boiled together till they come to a consistancy, the
proportion of each of the ingredients to be according to the strength
thereof respectively. And as for touching and concerning the
ingredients for the gunpowder from sulphur stones, without the use
of charcoal, the same are saltpetre and sulphur stones, with a very
small proportion of sulphur, according to the strength of the said
stones, and all to be prepared with any kind of spirits.
In witness whereof, I have hereunto put my hand and seal, this
Twenty-ninth day of May, in the year of our Lord One thousand
seven hundred and sixty-six.
