Year: 1749

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, DANIEL
JEWERS, of Saint Edmunds Bury, in the County of Suffolk, send greeting.
WHEREAS His most Excellent Majesty King George the Second, by His
Letters Patent under the Great Seal of Great Britain, bearing date the First
day of July, in the twenty-third year of His reign, did give and grant unto
me, the said Daniel Jewers, and William Lodge, of the same place, Gentle-
man, His especial lycence that I, the said Daniel Jewers, and the said William
Lodge, dureing the term of years therein expressed, should and lawfully might
use, exercise, and vend our "NEW LEVENTION OR METHOD OF MAKING PEARL-
ASHES FULL AS GOOD AS ANY MADE ABROAD BEYOND THE SEAS, AND IN MUCH GREATER
PERFECTION FOR USE AND STRENGTH THAN WHAT IS MADE IN THE KINGDOM OF
PRUSSIA OR ELSEWHERE, AND AT A MUCH CHEAPER RATE," within that part of Great
Britain called England, Dominion of Wales, and Town of Berwick-upon-
Tweed; in which said Letters Patent there is contained a provisoe obliging
me, the said Daniel Jewers, and the said William Lodge, or one of us, by
writing under our or one of our hands and seals, to cause a particular descrip-
tion of the nature of our said Invention, and in what manner the same is to be
performed, to be inrolled in His Majesty's High Court of Chancery within four
calender months after the date of the said recited Letters Patent, as in and
by the same, relation being thereunto had, may more at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Daniel Jewers, do hereby declare that the nature of our said Invention for

page_text: making pearlashes doth consist and is to be performed in the manner herein-
after mentioned (that is to say):-
Place in a proper place eight or ten deal vatts, sufficient to contain between
sixty and seventy bushels apeice, & under each vatt in the ground fix an
underbeck, likewise of deal, large enough to hold an hundred gallons of
liquor; &, having made an hole of an inch diameter thro' the bottom of the
upper vatt into the underbeck, they fill the upper vatt with wood ashes, and
drench the same with small lye and water till all the salts are drained from
them; &, when the lye becomes too weak to bear an egg, itt's esteemed too
small for boyling, and is then laid upon a fresh vatt of ashes instead of water,
so that four or five of these vatts are workt round one under the other in a
regular succession. The strong lye is boiled in a pan of cast iron, containing
two hundred gallons or thereabouts, till all the liquor is evaporated, and the
salt of the ashes left dry at the bottom of the pann, which is afterwards put
into a reverberating furnace built in the fashion of an oven in the inside, ten
feet in length, six feet in breadth, and fourteen inches in the heighth from the
floor of the furnace to the bottom of the arch towards the center. One foot on
each side of this furnace is seperated from the middle thereof by a partition of
brick, four inches in heighth, and four inches and a half in breadth; and under
each of these fireplaces are small pitts, about twelve inches in depth. Across
these fireplaces, about two inches below the middle floor, are fixed barrs of
iron, at the front and back of the middle part of the furnace; and alsoe at the
front of each of the fireplaces are flues to carry off the smoak, and the fire-
places are entirely separated from the middle of the furnace, for two feet and
an halfe in length, both at the front and back thereof. The salts being thus
placed in the middle of this furnice, great fires of pealed oaken wood are made
on each side, so as intirely to fill the middle part with one continual flame of
fire, which must be kept up till the goods are made of a fine pearl colour.
During this process of calciuation a person is employed to keep the goods
frequently stirring.
In witness whereof, I, the said Daniel Jewers, have hereunto sett my
hand and seal, this Fourteenth day of October, One thousand seven
hundred and forty-nine, in the said twenty-third year of King George
the Second

page_text: AND BE IT REMEMBRED, that on the said Fourteenth day of October,

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
LODGE, of Bury St. Edmunds, in the County of Suffolk, Gentleman, in com-
pliance with a provisoe contained in Letters Patent under the Great Seal of
Great Britain, bearing date the First day of July last, do hereby declare that
iny method of making pearlashes after the foreigne manner, by me discovered
and brought into this kingdom, doth consist and is to be performed in the
manner herein-after mentioned, that is to say:-
Place in a proper place eight or ten deal vatts, sufficient to contain abcut
sixty or seventy bushells apeice, and under each vatt in the ground fix an
underbeck, likewise of deal, large enough to hold an hundred gallons of liquor,
and having made an hole of an inch diameter thro' the bottom of the upper vatt
into the underbeck; then fill the upper vatt with wood ashes, and drench the
same with small lee and water till all the salts are drained from them. And
when the lee becomes too weak its esteemed too small for boiling, and is then
laid upon a fresh vatt of ashes instead of water, so that the whole number of
these vatts are workt round, one under the other, in a regular succession.
The strong lee is boyled in a pann of cast iron, containing two hundred gallons
or thereabouts, till all the liquor is evaporated, and the salts of the ashes left
dry at the bottom of the pann; which is afterwards put into a reverberating
furnace, built in the fashion of an oven in the inside, ten feet in length, six
feet in breadth, and fourteen inches in heighth from the floor of the furnace to
the bottom of the arch towards the center. One foot on each side of this
furnace is seperated from the midle thereof by a partition of brick, four inches
in height and four inches and a half in breadth, and under each of these fire-
places are small pitts, about twelve inches in depth. Across these fireplaces,
about two inches below the middle floor, are fixed barrs of iron at the front
and back of the middle part of the furnace; and also at the front of each of

page_text: the fireplaces are flews to carry of the smoak; and the fireplaces are intirely
seperated from the middle of the furnace for two feet and an half in length,
both at the front and back thereof. The salts being thus placed in the middle
of this furnace, great fires of pealed oaken wood are made on each side, so as
intirely to fill the middle part with one continued flame of fire, which must
be kept up till the goods are made of a fine pearl colour. Dureing this process
of calcination a person is employed to keep the goods frequently stirring.
In witness whereof, I, the said William Lodge, have hereunto set my
hand and seal, this Nineteenth day of October, One thousand seven
hundred and forty-nine, in the twenty-third year of the reign of King
George the Second.
