254 CHEAP Olt PAINTS. 



Painters* CO- A good chocolate colour is made by the additiQn of blue- 



lours cheaply hig^k in powdcr or lamp-black, till the colour is to your mind^ 

 and well pre- ' ' ' _ •' . 



pared with fish- and a lighter brown may be formed by adding ground white^ 



'"'^ lead. 



Note. — By ground lead, is meant white-lead groimd in oil. 



Yellow is prepared with yellow ochre in powder, in the same 

 proportion as the Spanish brown. 



Black is also prepared in the same proportion, using lamp- 

 black or blue-black. 



To "whiten Linseed-Oit, 



Take any quantity of linseed-oil, and to every gallon add 

 two ounces of litharge ; shake it up every day for fourteen 

 days, then let it settle a day or two ; pour off the clear into 

 shallow pans, the same as dripping-pans, first putting half a 

 pint of spirits of turpentine to each gallon. Place it in the 

 sun, and in three days it will be as white as nut-oil. 



This oil, before it is bleached, and without the turpentine, is 

 far superior to the best boiled oil, there being no waste or of-^ 

 fensive smell.

 dirt or dust collected in highways much travelled by horses and 

 carriages, and afterwards finely sifted, is the article recom- 

 mended, as possessing the properties required.

 mond, with his opinion respecting the painting of his Grace's 

 house and premises, at Earl's Court, Little Chelsea ; which wa$ 

 finished December, 1803. 



The Letter. 



SIR, 



I have just received your letter dated the 15th instant, and 

 am happy to find that your oil and colour business so well 

 stands the test of others, as well as that of myself. The fish- 

 pil composition you made use of, in all the painting you have 



done
