Steam Crutch.—far more effective way of mixing other substances as silicate of soda for example) with soap is by means of the steam crutch and crutching-pot, by aid of which a perfect incorporation of the materids is effected, without manual labour, in a few minutes, and the soap thus treated is much more uniform... 

The contents of the little pan are now allowed to flow into the pot, and soon after the required quantity has been crutched in, the revolving shaft is stopped, and the crutch raised out of the pot, which is then wheeled away to make room for a second pot, and is then drawm. up close to a frame, and its contents allowed to pour out by raising an iron gate situated near its base. Fig. 8 represents the crutching pot with its gate A raised by the lever B and at Fig. 7 is a drawing of the steam crutch, in which its several blades are shown. The bevel wheels above indicate its connection with the usual shafting. 

It is now commonly the practice to melt the crystals of sulphate of soda (Qlauber s Salt), or carbonate of soda in a steam-jacketed pan, and to ladle the liquid as required into the melted soap, after it has been put into the frames when the union of the materials is completed by crutching in the ordinary way or the liquid salts are introduced by means of the steam-crutch. 

To mix the fuller s earth with soap (resin soap by preference), the latter should be put into a steam jacket-pan, and the earthy powder spread over the surface, a little at a time, with constant crutching, until the full quantity has been introduced. Bearing in mind, however, that the dried clay is highly absorbent, after a certain quantity has been worked in, the mass will become considerably stiffened, and thereby render the crutching both laborious and difficult, therefore, to make up for the water expelled from the soap by evaporation, a small quantity of hot water may be added, if necessary, and finally, any desired perfume added, if for a toilet soap. In this way...

The whole being thoroughly crutched, the pan is covered and ponification allowed to proceed for one hour or one and a half hours. Should the saponification for some reason be retarded, a. little steam may be very cautiously admitted to the jacket of the pan, the mass well crutched until the reaction commences, and the whole allowed to rest the specified time.
