mixed together； then add the ground lead； first blending it with 2 1/2
galls。 of the prepared fish oil； after which； thin the whole with 2 galls。
of linseed oil and 2 galls。 of incorporated oil； and it will be fit for
use。 For garden doors； and other work liable to be in constant use； a
little spirits of turpentine may be added to the paint whilst laying on；
which will have the desired effect。
259。 BRIGHT GREEN PAINT
112 lbs。 yellow ochre in powder at 5 cts。 per lb。。。。 5。50
168 lbs。 road…dust。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。 0。25
112 lbs。 wet blue； at 20 cts。 per lb。。。。。。。。。。。。。。。。 22。40

7 1/2 galls。 linseed oil； at 90 cts。 per gal。。。。。。 6。75
Weights； 592 lbs。。。。。。。。。。。。。。 42。24
It will be seen that the bright green paint costs but about 7 cts。 per
lb。； ready to lay on； and the inventor challenges any colour…man or
painter to produce a green equal to it for five times the price。 After
painting； the colour left in the pot may be covered with water to prevent
it from sinking； and the brushes； as usual； should be cleaned with the
painting…knife； and kept under water。 A brighter green may be formed by
omitting the blue…black。 A lighter green may be had by the addition of 10
lbs。 of ground white lead。 Observe that the wet blue must be ground with
the incorporated oil； preparatory to its being mixed with the mass。
260。 STONE…COLOURED PAINT
Lime…water； 4 galls。。。。。。。。。。。。。。。。。 0。04
Whiting； 112 lbs。。。。。。。。。。。。。。。。。。。。 1。12
White lead； ground； 28 lbs。。。。。。。。。。 2。24

Prepared fish oil； 2 galls。。。。。。。。。。 1。20
Incorporated oil； 3 1/2 galls。。。。。。。 2。00
Linseed oil； 3 1/2 galls。。。。。。。。。。。。 3。15
Weights； 293 lbs。。。。。。。 9。85
The above stone…colour fit for use； is not three and a half cents per
pound。
261。 BROWN…RED COLOURED PAINT

Spanish brown； 112 lbs。。。。。。。。。。。。。。 3。36

4 galls。 incorporated oil。。。。。。。。。。。 2。28
4 galls。 linseed oil。。。。。。。。。。。。。。。。 3。60
Weights； 501 lbs。。。。。。。 12。12
This paint is scarcely two and a half cents per pound。 The Spanish brown
must be in powder。
262。 A GOOD CHOCOLATE COLOURED PAINT
This is made by the addition of blue black in powder； or lamp…black to
receipt No。261； till the colour is to the painter's mind； and a lighter
brown may be formed by adding ground white lead。 By ground lead is meant
white lead ground in oil。
263。 YELLOW PAINT
This is prepared with yellow ochre in powder； to receipt No。261； in the
same proportion as Spanish brown。
264。 BLACK PAINT
This is also prepared in the same proportion； as in receipt No。261； using
lamp…black or blue…black； instead of Spanish brown。
265。 WHITE PAINT
Slack a peck of nice； clean； fresh lime in a covered vessel； with water
which is boiling hot； when well slacked； strain it well； then add to it 1
1/2 lbs。 of finely ground rice； let the rice be boiled to a thin paste；
and stirred in while very hot； 1/2 peck of common salt； well dissolved in
warm water； 1/2 lb。 of clean glue； dissolved in water； and 1/4 lb。 of
whiting； when well mixed； add 5 gallons of very hot water； then stir well；
and let stand a few days well covered。 Pit it on hot； and it will stand
the weather as well as a good deal of white lead。 You may colour this
paint to suit your taste； using and stirring in well Spanish brown for a
red pink colour。 Take common clay finely powdered； and mixed well with
Spanish brown for a reddish stone…colour。 For yellow colour use yellow
ochre if you please； but chrome yellow makes a richer colour and less
does。 You may make the colours dark or light according to the quantity of
colouring matter used。
266 COMPOUND COLOURED PAINTS
The various colours that may be obtained by the mixture of other colours；
are innumerable。 I only propose here to give the best and simplest modes
of preparing those which are required for use。 Compound colours； formed by
the union of only two colours； are called by painters virgin tints。 The
smaller the number of colours of which any compound colour is composed；
the purer and the richer it will be。 They are prepared as follows：
267。 LIGHT GREY
This is made by mixing white lead with lamp…black； using more or less of
each material； as you wish to obtain a darker or lighter colour。
268。 BUFF COLOUR
This is made from yellow ochre and white lead。
269。 SILVER OR PEARL GREY
Mix white lead； indigo； and a very light portion of black； regulating the
quantities by the shade you wish to obtain。
270。 FLAXEN GREY
This is obtained by a mixture of white lead and Prussian blue； with a
small quantity of lake。
271。 BRICK COLOUR
This is prepared by mixing yellow ochre； and red lead； with a little white
lead。
272。 OAK WOOD COLOUR
Mix together three…fourths white lead； and one…fourth part umber and
yellow ochre； the proportions of the last two ingredients being determined
by the required tints。
273。 WALNUT TREE COLOUR
Two…thirds white lead； and one…third red ochre； yellow ochre； and umber；
mixed according to the shade sought。 If veining is required； use different
shades of the same mixture； and for the deepest places； black。
274。 JONQUIL
Mix together yellow； pink； and white lead。 This colour is only proper for
distemper
275。 LEMON YELLOW
Mix together realgar and orpiment； some object to this mixture on account
of the poisonous nature of the ingredients。 The same colour can be
obtained by mixing yellow…pink with Naples yellow； but it is then only fit
for distemper。
276。 ORANGE COLOUR
For this colour mix red lead and yellow ochre。
277。 VIOLET COLOUR
Make by mixing vermillion； or red lead； with black or blue； and a small
portion of white： vermillion is far preferable to red lead； in mixing this
colour。
278。 PURPLE
Made by mixing dark…red with violet…colour。
280。 GOLD COLOUR
This is procured by mixing massicot； or Naples yellow； with a small
quantity of realgar； and a very little Spanish white。
281。 OLIVE COLOUR
This may be obtained by various mixtures： black and a little blue； mixed
with yellow； yellow…pink； with a little verdigris and lamp…black； or ochre
and a small quantity of white； will also produce a kind of olive colour。
For distemper； indigo and yellow…pink； mixed with white lead or Spanish
white； must be used。 If veined； it should be done with umber。
282。 LEAD COLOUR
Mix together indigo and white lead or whiting。
283 CHESTNUT COLOUR
Mix red…ochre and black； for a dark…chestnut。 To make it lighter； employ a
mixture of yellow…ochre。
284。 LIGHT TIMBER COLOUR
For this colour mix together spruce…ochre； white and a little umber。
285。 FLESH COLOUR
Mix lake； white…lead； and a little vermillion。
286。 LIGHT WILLOW GREEN
This is made by mixing white with verdigris。
287。 STONE COLOUR
Mix white with a little spruce…ochre。
288。 DARK LEAD COLOUR
Mix black and white with a little indigo。
289。 FAWN COLOUR
Mix white lead； stone…ochre； and a little vermillion。
290。 CHOCOLATE COLOUR
Mix lamp…black and Spanish brown。 On account of the fatness of the
lamp…black； mix some litharge and red lead。
291。 PORTLAND STONE COLOUR
Mix umber； yellow ochre； and white lead。 The variety of shades of brown
that may be obtained； a
