Various recipes have been given for imparting a fine gloss to linen. Gum arabic, white wax, spermaceti, etc., have all been highly recommended, and are, no doubt, useful to a certain extent, but the great secret seems to lie in the quality of the iron used and the skill of the laundress. If the iron is hard, close grained and finely polished, the work will be much easier. Laundresses always have a favorite smoothing iron with which they do most of their work, and many of them have the front edge of the iron rounded so that great pressure can be brought to bear on a very small spot instead of being spread over a space the size of the whole face of the iron. If smoothing irons have become rough and rusty it will pay to send them to a grinder to have them not only ground but buffed (see aritcle on Polishing Metals). The greatest care should be taken not to allow them to get spotted with rust, and they should never be "brightened" with coarse sand, ashes, emery, etc. If it is necessary to polish them, rub them on a board, or preferably a piece of leather charged with the finest flour of emery, obtained by washing, or better still, jeweller's rouge.
