«N MAKING CHEAP OIL PAINTS. IfS 



To prepare the Vinegar for the Oil, 



Into a cask which will contain about forty gallons, put 32 gallons 

 of good common vinegar; add to this 12 pounds of litharge, and 

 12 pounds of white copperas in powder ; bung up the vessel, and 

 shake and roll it well twice a day for a week, when it will be fit to 

 put into a ton of whale, cod, or seal oil ; (but the Southern whale 

 oil is to be preferred, on account of its good color, and having little 

 or no smell :) shake and mix all together, when it may settle until 

 the next day ; then pour oti" the clear, which will be about seven- 

 eighths of the whole. To this clear part add twelve gallons of 

 linseed-oil, and two gallons of spirit of turpentine ; shake them 

 well together, and after the whole has settled two or three days, it 

 will be tit to grind white-lead and all fine colors in ; and when 

 ground, they cannot be distingtiished from those ground in linseed- 

 oil, unless by the superiority of their colors. 



If the oil is wanted only for coarse purposes, the linseed-oil and 

 spirit of turpentine may be added at the same time that the pre- 

 pared vinegar is put in ; and after being well shaken up, it is fit for 

 immediate use, without being suffered to settle. 



The vinegar is used to dissolve the litharge, and the copperas 

 accelerates the solution and increases the drying quality. 



The residue, or bottom, when settled, by the addition of half its 

 quantity of fresh lime-water, forms an excellent oil for mixing with 

 all the coarse paints for preserving outside work. 



Note. — All colors, ground in the above oil, and used for inside 

 work, must be thinned with linseed-oil and spirit of turpentine.

The method of preparing various Impenetrable Paints. 



First — Sxihdiied Green. 



Fresh lime-water, 6 jralls. I Wpt blue, 20 lbs. 



Ilnail-diist. finely sifted, 112 lbs. | Residue of the oil. 3 jralls. 



\Vliitinir, 112 lbs. I Yellovv-oclire, in powder, 24 lbs. 



r.hie-blac-k, 30 lbs. | 



This composition will weigh 368 pounds, which is scarcely one 

 penny per pound. To render the above paint fit for use, to every 

 eisiht pounds add one quart of the incorporated oil. and one quart 

 of linseed-oil ; and it will be found to be a paint with every requi- 

 site quality of beauty, durability, and cheapness ; and, in this st^te 

 of jueparation, docs not exceed two-pence half-penny per pound : 

 whereas the coal-tar paint of the same color, is six-pence per 

 pound. 



The mi'thod of mixing the Ingredie7ii3 for the Subdued Green. 

 First, pour six gallons of lime-water into a large tub, then throw- 

 in 112 pounds of whiting ; stir it round well with a stirrer ; let it 

 settle for about an hour, and stir it again. Now you may put in 

 the 112 pounds of road-dust, mix it well ; then add the blue-black, 

 after which, the yellow-ochrs ; and when all is tolerably blended, 

 fake il out of the, tub, and put it on a large board or platform, anH
