Pounce
a fine powder, such as pounded gums and arach and cuttlefish bonus, used to dry up the ink on a fresh written manuscript; now superseded in the United States by blotting paper, except in the case of parchment. The word is also applied to charcoal dust inclosed in some open stuff, as muslin, etc., to be passed over holes pricked in the work, to mark the lines or designs of a paper underneath. It is used to some extent by embroiderers to transfer patpainters, sometimes by engravers, and in terns upon their stuff; also by fresco varnishing.
