day ; then pour off the clear, which will be about feven- 
eighths of the whole. To this clear part add twelve gal¬ 
lons of linfeed-oil, and two gallons of fpirit of turpentine ; 
(hake them well together, and, after the whole has fettled 
two or three days, it will be fit to grind white-lead and 
aJl fine colours in ; and, when ground, cannot be diftin- 
guifhed from thofe ground in linfeed-oil, unlefs by the 
(uperiority of its colour. 
If the oil is wanted only for coarfe purpofes, the linfeed- 
oil and oil of turpentine may be added at the fame time 
that the prepared vinegar is put in 5 and, after being well 
(haken up, is fit for immediate ufe, without being fuffered 
to fettle. The vinegar is to dilfolve the litharge ; and the 
copperas accelerates the difiolution, and ftrengthens the 
drying quality. The refidue, or bottom, when fettled, 
by the addition of half its quantity of frelh lime-water, 
forms an excellent oil for mixing with all the coarfe paints 
for preferving outfide-work. 
All colours ground in the above oil, and ufed for infide- 
work, muft be thinned with linfeed-oil and oil of turpen¬ 
tine. The oil mixed with lime-water, is called incor¬ 
porated oil.

This compofition will weigh 368 pounds, which is

will be found a paint with every requifite quality, both of 
beauty, durability, and cheapnefs ; and in this (late of pre¬ 
paration does not exceed twopence-halfpenny per pound, 
whereas the coal-tar of the fame colour is fixpence.

This excellent bright-green does not exceed threepence¬ 
farthing per pound ready to lay on; and the inventor chal¬ 
lenges any colour-man or painter to produce a green 
equal to it for eighteen-pence. After painting, the colour 
left in the pot may be covered with water, to prevent it 
from (kinning; and the brufhes, as ufual, (hould be 
cleaned with the painting-knife, and kept under water. 
A brighter green may be formed by omitting the blue- 
black ; and a lighter green may be made by the addition 
of ten pounds of ground white-lead. A variety of greens 
may be obtained, by varying the proportions of the blue 
and yellow. Obferve that the wet-blue muft be ground 
with the incorporated oil, preparatory to its being mixed 
with the mafs.

This moft excellent paint is fcarcely one penny per pound. 
A good chocolate-colour is made by the addition of 
blue-black in powder or lamp-black, till the colour is to 
your mind, and a lighter brown may be formed by adding 
ground white-lead. 
Yellow is prepared with yellow ochre in powder, in the 
fame proportion as the Spanifh-brown. Black is alfo 
prepared in the fame proportion, ufing lamp-black or blue- 
black. 
5. White.- —In a fubfequent communication, Mr. Vatir 
lierman added the following receipt for a conftant white 
for infide-painting. This paint, the author obferves, is 
not entirely free from fmell in the operation, but becomes 
dry in four hours, at the end of which time the fmell is 
entirely diftipated. 
“To one gallon of fpirits of turpentine add two pounds 
of frankincenfe ; let it fimmer over a clear fire until dif- 
folved ; drain it, and bottle it for ufe. To one gallon of 
my bleached linfeed-oil, add one quart of the above, (hake 
them well together, and bottle it alfo. Let any quantity 
of white-lead be ground with fpirits of turpentine very 
fine; then add a fufficient portion of the laft mixture to 
it, until you find it fit for laying-on. If in working it 
grows thick, it muft be thinned with fpirits of turpentine. 
It is a flat or dead white.”
