Dyeing of silk with color extracted from branches of apple has been carried out by the method used in a general handcraft dyeing. With the view of giving a scientific examination to that, in this report, the influences of color concentration and of mordant metal were examinated. The color differences of dyed silk cloths were measured on a color difference meter.The brightness of color of dyed cloth was decreased with the increase of concentration of dyestuff, and the values were equilibrated above 500％ o. w. f.. The influences of kinds of metal (Al, Cr, Cu, Fe, and Sn) on color were remarkably observed. From 50％ o. w. f. of dyestuff the color differences were observed, and beyond 500％ o. w. f. these came up to constant.In the dyeing of silk with the extracted dyestuff from apple branches, various series of color are available by the combination of the dyestuff concentration and the kind of mordant metal.
