23 galls of the thick dirty vsh bottoms out of tub – put it into steam cistern add,23 galls linseed oil – and apply steam heat for 3 hours the rest of that day,Memm the bottoms and 3 galls of the oil are put together then heated till it liquifies, when the rem of the oil may be added,The next day the steam is turned strongly on so as to heat the mixture well, & continued the whole of the day stirring 4 or 5 times during the day, but having it from 4 o clock till 7 without stirring at all. Turn off steam & allow the impurities to subside ,Next day – a dark coloured oil is the result – of which may be dipped off,32 galls of “first colour oil” for canvass,This oil had a skin on it,About 15 galls of thick black liquid remains which is put into the oil bottom tub for using with painters grd colours.,At the bottom off all the skins & other insoluble matters have caked at the bottom – then are use & may be thrown away,When this is used it is stirred up in the cistern before any is taken out,I valued this with labour included at 5 per gall – being capital stuff for canvass 1st colour (Hlh?) ,
