page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
SCOTT, of the County of Edinburgh, in Scotland, Surveyor of Land, send
greeting.
WHEREAS His most Excellent Majesty King George the Third, by His
Royal Letters Patent under the Great Seal of Great Britain, bearing date
the Twenty-third day of January, in the fifth year of His reign, and in the
year of our Lord One thousand seven hundred and sixty-five, did give and
grant unto me, the said John Scott, my exors, adñiors, and assigns, His
especial lycence, full power, sole priviledge and authority, that I, the said
John Scott, my exors, adiñors, and assigns, should and might, during the
term of years therein expressed, make, use, execise, and vend, throughout
that part of His Majesty's Kingdom of Great Britain called England, and
His Dominion of Wales, and Town of Berwick-upon-Tweed, my "NEW ART
AND MISTERY OF MAKING GLASS FROM ONE SINGLE MATERIAL, WITHOUT THE HELP
OF ANY COMPOSITION, WHICH GLASS IS CAPABLE OF BEING BLOWN AND FASHIONED
INTO VESSELLS OF USE OF ANY FORM AND OF A STRONGER QUALLITY THAN GREEN
GLASS; AND ALSO A NEW AND DIFFERENT APPARATUS AND FURNACES FOR MAKING
THIS GLASS; AND ALSO MY NEW ART AND MISTERY OF MAKING PIG IRON FROM ONE
SINGLE MATERIAL NEVER BEFORE USED BY THE MAKERS AND MANUFACTURERS OF PIG
IRON IN GREAT BRITAIN, WITH AN APPARATUS AND FURNACES FOR MAKING THIS
PIG IRON ALTOGETHER NEW AND DIFFERENT FROM THE BLAST FURNACES NOW USED
FOR MAKING OF PIG IRON, AFTER A NEW AND DIFFERENT MANNER, AND WITH FAR
LESS EXPENCE, BY THE METHODS NOW USED IN MAKING GLASS AND PIG IRON;" in

page_text: which said recited Letters Patent is contained a proviso obliging me, the said
John Scott, by writing under my hand and seal, to cause a description of
my said Invention to be inrolled in Ilis Majesty's High Court of Chancery
within four callendar months from the date of the said recited Letters Patent,
as in and by the same, relation being thereunto had, may more fully and at
large appear.
NOW KNOW YE, that in complyance with the said proviso, I, the said
John Scott, do hereby declare that my said Inventions are made and performed
in manner following (that is to say) :-
Take of such stones or rocks commonly called or known by the name or
names of whinstones or whinstone rocks as are attracted by the magnet with-
out being burnt or or calcined, which being broken to pieces put into furnaces.
After the same are heated, and, by force of the fire only, they are resolved into
glass and pig iron; the iron, by reason of its specifick gravity, falls to the
bottom, and the glass remains above it in the furnace untill they are caused to
run out of the furnaces, each by a proper vent made for that purpose; and the
whinstones that are not attracted by the magnet, and which do not contain iron,
are reduced to glass in like mañer, which glass thus made may be blown and
fashioned into any size, form, or shape, for such uses and purposes as may be
thought fit, or it may be used by the makers and manufacturers of common
green glass bottles, and mixed with any part or portion of common green glass,
and blown and fashioned in any shape, as above.
The apparatus or furnaces for making glass and pig iron are constructed and
used as follows:-There is a house built of any convenient size. On one side
within the house is built a furnace that is to work without any bellows; the
whole length may be about twelve feet, and the breadth within about three feet,
and the heigth of the furnace, from the bottom to the roof, about two feet. The
fireplace is a grate or branders matle of cast iron, and occupies a space of three
feet by two feet. Opposite to the middle of the fireplace there is a hole of nine
inches square, thro' which the coales or feowell are conveyed, to make and repair
the fire, and about two feet from the fire there is a door made in the front of
the furnace for conveying the stones into it. At the extremity of the furnace,
opposite to the fire, and within, there is a pit or well of a convenient depth
and width which the metalls descend into as they are fluxed or melted. From
this pit there are two vents through the wail of the furnaces, the one for
running the iron, and the other for conveying the glass out of the furnaces
when it is sufficiently melted. The soal and roof of the furnaces are nearly
paralell to one another, and have a sloping or oblique direction from the fireplace
to the pitt which is below the levell of the fireplace. Immediately over the

page_text: pitt is the smoke vent carryed up in the wall of the house to about forty or
forty-six feet in height. The inside of the furnaces are built of what is
commonly called the firebricks, as also the inside of the chimney stack or
smoke vent. The bottom of the furnaces are only sand of a particular kind
that is not apt to melt; which furnaces and apparatus may be varied in size
and shape as occasion shall require.
