S.T.F. is in despair because he has, apparently, ruined a favourite plaster cast by following the advice given in the "Art Column" of a weekly journal. He says he was told to use a handful of bread crumbs, or some sponge rubber !" He did so, and the result is that " the cast is in a worse condition than before." Of course it is. There is only one way to clean a plaster cast without risk of injuring it, and that is to cover it with starch paste, applied with a soft brush, and let it dry. The starch will peel off. bringing away with it all impurities and leaving the plaster as fresh and white as ever it was. To keep it clean for the future, dissolve yellow beeswax in turpentine, and let the cast absorb as much of it as it can. This will give it a soft ivory tint without any objectionable glossiness. A cast treated in this manner, after a little while, will acquire a tone scarcely distinguishable from that of real ivory.
