Where the manufacturer has steam-power at his disposal, the apparatus may be connected with the transmission and allowed to run for 48 to 60 hours during working time. After the expiration of this time, proceed to strain off the finished extract (No. 1) as follows: Over a clean tin vessel stretch a close, white linen cloth, and pour the entire contents of the apparatus upon the latter; the liquid portion runs through the cloth into the vessel, while the pomade remains behind upon the cloth. Finally, the cloth is thoroughly wrung out in order to obtain as much alcoholic extract from the pomade as possible. Bring the extract, No. 1, thus obtained into a glass flask, allow it to stand in a cool cellar for about 48 hours, and then filter it through paper into another glass bottle. This filtering through paper is necessary, even if the extract should appear clear and pure, as, in straining, not only do small particles of fat pass through the cloth, but are also dissolved in the extract. By quietly standing in a cool cellar these particles of fat are separated and appear as white flakes on the bottom and sides of the flask. At a higher temperature, these flakes melt and appear as drops of oil on the bottom of the flask. If filtering were omitted, these particles of fat would be transferred to the extracts and thus cause stains upon handkerchiefs, clothing, etc. If the manufacturer has not a cool cellar at his disposal, the fatty particles are readily separated by placing the flasks containing the extract upon ice, and filtering immediately after separation is complete. The fat then remains upon the filter. The pomade remaining upon the straining cloth is, without being previously melted, returned to the apparatus, and, after adding the same quantity of alcohol (3½ quarts to every 2 lbs. of pomade), the mixture is again worked as previously described. The straining off and filtering of extract No. 2 is effected in precisely the same manner as extract No. 1. The pomade upon the cloth is now brought for the third time into the apparatus and, after adding 3½ quarts of alcohol for every 2 lbs. of pomade, subjected to the same treatment as for extracts Nos. 1 and 2. After thoroughly wringing out the cloth containing the pomade, the latter is brought into a clean tin vessel and entirely melted upon the water-bath. The vessel containing the melted pomade is placed in a cool cellar and, if after complete cooling, a liquid appears upon the surface, it is added to the flask containing extract No. 3. This extract, No. 3, is used in place of alcohol when preparing, the next time, extract No. 1 from the same kind of pomade. In this manner, an extract No. 1 of still greater strength is obtained, and by treating the pomade three times with alcohol, it is more completely exhausted. The exhausted pomade can, in conjunction with fresh fat, be used for ordinary hair pomades.
