Steep your ivory or bone in aquafortis (nitrous acid) diluted with twice its quantity of water, then take it out, and put it into your scarlet dye till the color is to your mind. Be careful not to let your aquafortis be too strong; neither let your ivory remain too long in it. Try it first with a slip of ivory, and if you observe the acid has just caused a trifling roughness on its surface, take it out immediately, and put it into the red liquid, which must be warm, but not too hot. A little practice, with these cautions, will enable you to succeed according to your wishes; cover the places you wish to remain unstained with white wax, and the stain will not penetrate in those places, but leave the ivory of its natural colour.
