To make a suitable composition for repairing an ebonised picture-frame, crush a small quantity of gilder's whiting and mix it in a pipkin with sufficient dry lampblack to make a slate-coloured powder. Now pour a small quantity of very thin glue into the middle of the powder and mix the Litter into a ball, well kneading with the hands. Place this putty in a, wet state on the frame and build up all sharp edges to correspond with the original work. When dry and hard, sandpaper the repaired parts until level and smooth. Finish with a coat of black enamel which gives a good hard surface.
