«8^2 Metmir oA a Method of Uoufe Pa!nlt>tg. 



This metliod of painting befides cods ten fols the toife ; but as we have before obferved, 

 the painting in diftemper with milk does not cofl more than one fol, fix deniers, to which 

 ■we rauft add a fmall matter for the expence of laying it on, as a man can cover a great 

 number of toifes in a day. 



But I fho.uld prefer for thefe purpofes the painting with the refinous compofition and 

 milk, -ufing the lime and yellow ochre, with or without the addition of Spanifli white. 

 This paint would laft twenty or thirty years without alteration ; I know of nothing but the 

 Hittification of the walls which coold injure it, and this is a flow procefs. 

 i I have fpoken much to the difadvantage of painting in oil and in diftemper, and I hare 

 pleaded the caufe of my new procefs ; but the theory on which I founded my preparation, 

 and the experience I have had, fpeak ftrongly in favour of my conclufions. 



I fee only one objeftion, namely, the ditficulty of procuring milk. This is far from 

 being a difficulty, for there is more want of buyers for milk, than milk for the buyers. In 

 the feafon of fruits in France there is fcarcely any demand for milk, and in many places 

 ■they are but very indifferently fkilled in making cheefe or butter. The fummer is the 

 feafon for painting. The confumption of milk at that time will even be advantageous lo 

 the farmer, and in no refpe£t detrimental to thofe who confume it as food. It may alfo 

 be obferved, that for this purpofe the milk may be brought from a much greater diftancc 

 than it could for confumption as food, for if half the lime be added at the place where the 

 milk was produced, it may then be carried without becoming four or clotting, in a perfect 

 ftate to the place of its deilination. Little objedion can be made in the country as to the 

 fcarcity of milk. 



The political obje€lion, that the houfe painters wonld by this praftice be reduced to 

 beggary, would alfo be a great objediion with me to the procefs, if I were not convinced 

 from numberlefs inftances, that the increafed confumption of a cheap thing more tlian 

 compenfates for the difference of charge by the abundance of employ it gives. Out of a 

 hundred perfons who would paint their apartments at twenty-five francs, there are fcarcely 

 five who would paint, if the price were fifty crowns. Thofe who hold their dwellings 

 only for a fhort term, would adopt this ufeful and wholefome procefs when they knew its 

 cheapnefs; fo that upon the whole we might reafonably infer, that twice thewumber of 

 "toainters might be employed in the workmanfhip, when the materials could be afforded fo 

 much better and cheaper. 



The facility with which this work may be performed, may alfo be of fome advantage in 

 preventing workmen from giving the law to their employers -, for there arc many opera- 

 tions of domeftic employ which are much more difficult than this. The mixture may he 

 brought to a ftill greater degree of perfe6lion. Fat or tallow may bt fubflituted inilead of 

 oil, and wax inflead of Burgundy pitch. 



I therefore invite thofe chcmifts who devote their exertions to the ipiprovement of the 



arts,, to attend to this method of painting, and fix the grogortionsi to ascertain whether
