Year: 1770

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
RICHTER, send greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of Great Britain, bearing date the
Twenty-eighth day of December, in the eleventh year of His reign, give and
grant unto me, the said John Richter, His especial licence that I, the said
John Richter, during the term of years therein expressed, should and law-
fully might use, exercise, and vend, within England, Wales, and Town of
Berwick-upon-Tweed, my Invention of "AN ART OB METHOD OF INLAYING
SCAGLIOLIA OR PLAISTER IN AND UPON MARBLE AND METALS TO IMITATE FLOWERS,
TREES, FRUITS, BIRDS, BEASTS, LANDSCAPES, AND ALL SORTS OF ORNAMENTS;" in
which said Letters Patent there is contained a provisoe obliging me, the said
John Richter, under my hand and seal, to cause a particular description of
the nature of my said Invention, and how the same is to be performed, to be
inrolled in His Majesty's High Court of Chancery within four calendar
months after 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 compliance with the said provisoe, I, the said
John Richter, do hereby declare that my said Invention of an Art or Method
of Inlaying Scagliolia or Plaister in and upon Marble and Metals to imitate

page_text: Flowers, Trees, Fruits, Birds, Beasts, Landscapes, and all sorts of Ornaments,
is described in the manner following (that is to say):-
First, procure statuary marble, or metal, and which must be finely polished.
Secondly, take size water, and mix the same with common whiting; brush
the same all over the polish'd marble or metal; when the same is dry, draw
the design thereon, and cause that part within which is meant to be inlaid
to be cut out a quarter of an inch deep.
Thirdly, take the scagliolia or plaister, and which must be finely sifted; have
all the necessary colours finely ground, which must be such as are used in oil by
the painters; mix the scagliolia or plaister into a paste with size water, add to
the same such colours as the design requires, then with a small trowell lay the
same into those cavities that are intended to be filled up, and let the same
remain until it becomes dry and hard, after which level the same to the face
of the marble or metal with a small plane or knife, which must be very
sharp. Care must be taken that the corners of the plane or knife do not
take off the polish of the marble or metal. Then take scuttle bone and
water, and grind the same more level than the plane or knife may have left
the same; after washing the same well, take scagliolia or plaister, mixed with
the same size water and colours, but more liquid, then lay the same over
the washed parts with a trowell, so as to stop those pores which may be per-
ceived. Let this remain until the same comes to be dry and hard, and
then again, with scuttle bone and water, grind that stopping off, so that
none remains but in the pores.
Fourthly, let the work dry for six days, then paint the same over with
olive oil. Great care must be taken not to oil the marble or metal. When
the same is dry take tripoli, ground into a fine powder, and with a piece of
soft leather rub over the work until the same has obtained a fine polish.
Fifthly, the ground of the marble or metal must be made rough for the
scagliolia or plaister to stick the better upon.
Lastly, in order to lay scagliolia on metal without the metal appearing
on the surface, the scagliolia must be laid on mixed with such colours as are
intended to be the ground, the same to be levelled as above, and stop the
ground, and draw the design upon it; the rest of the proceeding as above-
described.
In witness whereof, I, the said John Richter, have hereunto set my
hand and seal, the Fourteenth day of March, One thousand seven
hundred and seventy-one
JOHN RICHTER (L.B.)
