RALPH WEDGWOOD, of the Hill, in Burslem, in the County of Stafford, Potter,
send greeting.
WHEREAS His most Excellent Majesty King George tho Third, by His
Letters Patent under His Great Seal of Great Britain, bearing date at
Westminster, the Third day of October, in the thirty-sixth year of His reign,
did grant unto me, the said Ralph Wedgwood, my exors, adiñors, and assigns,
His said Majesty's especial licence, full power, sole priviledge and authority, that
J, the said Ralph Wedgwood, my exors, adñiors, and assigns, and every of them,
by myself and themselves, or by mine and their deputy or deputies, servants or
agents, or such others as I, the said Ralph Wedgwood, my exors, adiñors, or
assigns, should at any time agree with, and no others, 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 NEW DISCOVERED AND INVENTED COMPO-
SITION FOR MAKING GLASS UPON NEW PRINCIPLES, WHEREBY GREAT ADVANTAGES WILL
ARISE TO THE PUBLIC IN EVERY INSTANCE WHERE SUCH COMPOSITION IS APPLICABLE,"
within that part of His Majesty's Kingdom of Great Britain called England,
His Dominion of Wales, and Town of Berwick-upon-Tweed, in such manner as
to me, the said Ralph Wedgwood, my exors, adññors, and assigns, or any of
them, should in his or their discretions seem meet, and that I, the said Ralph
Wedgwood, my exors, admors, 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 Invention,
for and during the term of years therein mentioned, to have, hold, exercise,

page_text: aml enjoy the said licence, powers, priviledges and advantages therein-before
granted or mentioned to be granted unto me, the said Ralph Wedgwood, my
exors, admiors, 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; in which said recited Letters Patent is contained a proviso that if
I, the said Ralph Wedgwood, should not particularly describe and ascertain the
nature of my said Invention, and in what manner the same was 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 one calendar
month next and immediately after the date thereof, that then the said recited
Letters Patents, and all liberties and advantages whatsoever thereby granted,
should utterly cease, determine, and become void, anything therein-before con-
tained to the contrary in anywise notwithstanding, as in and by the said recited
Letters Patent, reference being thereunto had, will moro fully and at large
appear.
NOW KNOW YE, that 1, the said Ralph Wedgwood, do hereby declare
my said Invention, and declare that the same is of the description and to be
performed in manner following (that is to say):-
=
My new-invented composition for making glass is male of the following
articles (that is to say), alkaline salts, pieces or parts of china or earthenware
pitchers, or pieces of baked clay, old plaister moulds, or calcarous carths,
borax, silecious carths, and terra ponderosa; and I use these articles in the
following manner (that is to say), I use the alkaline salts and borax either in
a state of powder or of solution; but I prefer to use these articles in solution.
When I use. the alkalino salts in solution, I cause to be made a solution of
alkalino salts in water, and into this solution I cast pieces or parts of china or
carthenware pitchers, pieces of bakod clay, the same being first heated red hot.
To these I add old plaistor moulds or calcareous earth, first slacking them in a
solution of borax in water, when I use borax in solution; and I also add
silecious earths and terra ponderosa, all which articles I cause to be ground
together, and then dried over a slow fire. When I apply the alkaline salts
and borax in a state of powder I use them in the sanic manner as they are 'now
used in making of glass. When these several articles are ground together and
dried over a slow fire, I put the whole into a melting pot, and cause it to be
fused with an intense heat, and when in perfect fusion I pour it from the
melting pot into cold water. The quantities of the several articles will depend
on the quantity of glass intended to be made, and the proportion of each
article inust necessarily depend in some degree on the quality of the respectivo

page_text: articles and also on the hardness or softness of the glass required, but by
attending to all or any of the following proportions of the several articles so to
be used my composition will be mado.
To make the solution of alkaline salts in water.-When I adopt the solution
I use of alkaline salts from ten to fifty pounds, and all the intermediate pro-
portions. and of water from twelve to seventy quarts, and all the intermediate
proportions; of the pieces or parts of china or earthenware pitchers I use from
fifty to one hundred and fifty pounds, and all the intermediate proportions; but
if I use baked clay, I use from eighty to one hundred pounds, and all the
intermediate proportions.
To make the solution of borax in water.-When I adopt the solution I use
of borax from three to ten pounds, and all the intermediate proportions, and
of water from ten to fifty quarts, and all the intermediate proportions, and of
calcareous earths I use from forty to one hundred pounds, and all the inter-
mediate proportions. Of silecious carths I use from fifty to one hundred
pounds, and all the intermediate proportions, and of terra ponderosa I use
from five to twenty pounds, and all the intermediate proportions. When the
alkaline salts and borax are applied in a state of powder, I use each of the
articles in the same proportion as when they are used in the solution. Other
proportions of these several articles may make a composition for glass on my
new principle; but by attending to these proportions it will be made with
greater profit and advantage than the present mode of making glass, and with
a great saving of health to the labourers employed.
In witness whereof, I, the said Ralph Wedgwood, have hereunto set
my hand and seal, the Second day of November, in the thirty-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 ninety-six.
