To the above add two galls. of the incorporated oil, and 2 galls. of the linseed oil to thin it for use, and it will not exceed two cents and a quarter. The lime-water, whiting, road-dirt, and blue-black, must be first 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 10 lbs. blue-black, at 5 cts. per lb............... 0.50 6 galls. of lime-water............................ 0.06 4 galls. fish oil, prepared....................... 2.40 7-1/2 galls. incorporated oil..................... 4.28 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.
