page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PETER
BROWNE, of the Parish of Saint Mary-le-Bow, in the City of London, Painter,
send greeting.
WHEREAS I, the said Peter Browne, together with John Tempest
Christian, of Smarden, in the County of Kent, Gentlemen, did, by our petitions
humbly represent unto His present most Excellent Majesty King George the
Third, that we had, with great study, pains, and industry, invented "A NEW
METHOD OF PAINTING SILKS AND SATTENS IN OIL COLOURS, AND OF RENDERING THEM
DURABLE BY PRESERVING THE COLOURS FROM THE COMMON INJURIES ARISING FROM
WATER OR FRICTION, WHICH INVENTION AFFORDS THE ELEGANCE OF RICH BROCADE TO
THE SLIGHTEST LUTESTRING;" wherefore and in regard we are the first and true
Inventors thereof, we most humbly prayed that His said Majesty would be
graciously pleased to grant unto us His Royal Letters Patent under IIis Great
Seal of Great Britain for the sole vending and painting the said silks and sattens
in oil colours within that part of Ilis Kingdom of Great Britain called England,
Ilis Dominion of Wales, and Town of Berwick-upon-Tweed, and His Colonies
and Plantations abroad; His said Majesty, being willing to give encouragement
to all arts and inventions which may be for the publick good, was graciously
pleased to condescend to our request; and therefore, by His Royal Letters
Patent, bearing date at Westminster, the Eighteenth day of January, in the
fourth year of His reign, did, for Him. His heirs and successors, give and

page_text: grant unto us, the said John Tempest Christian and Peter Brown, our
executors, administrators, and assigns, His especial licence, full power, sole
privilege and authority, that we, the said John Tempest Christian and Peter
Brown, our executors, administrators, and assigns, and every of us, by
ourselves and themselves, or by our deputy or deputies, servants or agents, or
such others as we should agree with, and no others, from time to time and at
all times thereafter during the term of years therein-after mentioned, should
and lawfully might make, use, exercise, and vend our said Invention within
that part of His said Majesty's Kingdom of Great Britain called England,
Ilis Dominion of Wales, and Town of Berwick-upon-Tweed, and also in
His Colonies and Plantations abroad, in such manner as to us, our executors,
administrators, or assigns, or any of us, should in our discretions seem meet,
and that we, our executors, administrators, and assigns, should and lawfully
might have and enjoy the whole profit, commodity, benefit, and advantage
from time to time coming, growing, renewing, and arising by reason of the
said Invention, for and during the term of years therein mentioned; to have,
hold, exercise, and enjoy the said lycence, power, privileges, and advantages
therein-before granted or mentioned to be granted, unto us, the said John
Tempest Christian and Peter Brown, our executors, administrators, and
assigns, for and during and unto the full end and term of fourteen years from
the date thereof next and immediately ensuing, and fully to be compleat and
ended, according to the Statute in such case made and provided: And
whereas in the said Letters Patent there is contained a proviso that if we, the
said John Tempest Christian and Peter Brown, or one of us, should 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 the hand and seal of one of us, and cause the same
to be inrolled in His Majestie's High Court of Chancery within four kalendar
months from 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.
NOW KNOW YE, that in compliance with the said proviso, I, the afore-
said Peter Brown, do hereby describe and ascertain the nature of our said
Invention, and the manner in which the same is to be performed, as follows
(that is to say), :-
The receipt for preparing silks and sattens to be painted in oil colours, as
also the colours themselves. Gross materials: isinglass, half a pound; virgins
wax, half an ounce; white sugar, a quarter of an ounce; flake white, levigated,

page_text: one pound and an half; clean water, two quarts. The method of compounding
these ingredients in order to the above purpose: First dissolve the isinglass in
the water in a clean skillet over a very gentle fire, add the wax and sugar,
and continue stirring till they likewise are dissolved, strain it through a fine
lawn sieve into another clean skillet, stir in the flake white, powdered fine,
place it again on the fire, keeping it stirr'd for about ten minutes, pour it into.
a stone bottle and keep it stopt close for use; this we call ursplash. In the
proper application of this compound it is necessary to have blocks, in the
forming which observe the following method: take a piece of the finest felt
from the hat makers and dip it into the following mixture, compounded of
isinglass, an ounce; clean water, one pint; proof spirits, quarter of a pint ;*
dissolve the isinglass in the water, and let it boil half away, add the spirits
and let it just boil; when the felt is thus dipt, lay it to dry; when almost dry,
press it close in a screw press, in which let it remain an hour, take it out
and let it become perfectly dry in the open air; when dry, fasten it on a block
of asp wood, from three inches square to that of twelve inches square, in
proportion to the size of what it is to be impressed, on which the felt must be
carved and the extremities cut away; when the blocks are thus prepared
they are ready to be charged, in which the following method must be
observed: boil the ursplash, and whilst it is boiling pour it on a board
covered with fine cloth, and immediately press the carved block on it, and it
is charged; the silk is made ready to receive the ursplash from the impression
of the block by being strained on a cloth table or frame, where it must remain
till it is quite dry. To prepare the colours; grind them fine in spirits of wine
and place them on chalk stones to dry, when dry grind them again with the
finest walnut oil, keep them close stopt in glass or fine bladders for use.
Method of using the colours: mix them with fine oil of turpentine on the
pallate, as they are used to the most delicate temper, and proceed to work.
In witness whereof, I, the said Peter Brown, have hereunto set my
hand and seal, the Twelfth day of May, in the fourth year of the reign
of His Majesty King George the Third, and in the year of our Lord
One thousand seven hundred and sixty-four.
