CASTING RECESSO FITTINGS 

In the case of "Recesso" fittings, the next product to be considered, the making process differs radically from that of tiles. "Recesso," we need hardly explain, is the trade name we apply to the built-in glazed earthenware receptacles for soap, sponge, etcetera, which, introduced by us some twelve years ago, are now installed almost as a matter of course in every well-appointed bathroom. These invaluable aids to hygiene are made by the "casting" process. Plaster-of-Paris moulds of the articles required are prepared, and into them is poured a dense though quite fluid form of the above described " slip," which is delivered to the casting shops through iron pipes. In the mould the slip is quickly relieved of most of its moisture by the absorbent plaster, and in a few hours the casting has set hard enough to be removed, whereupon it is carefully finished by hand and placed in a rack to dry. 
Casting, of course, is a much slower operation than machine pressing, but it lends itself to the production of articles much too complex for the latter process.
