— What is used in imitation sealing-wax? I used to get an excellent sealing-wax, but of late years it appears to me to be greatly deteriorated in quality. —T. R., Indianapolis, Ind.
Answer. Good sealing-wax is made of shellac and vermilion, or other mineral coloring, according to the color desired. Much of the cheap sealing-wax sold today is adulterated with resin and the cheaper red lead in place of vermilion.
