ABSTRACT:
Liquid soap is made in small quantities in the home by mixing a fat, such as left over cooking fats, with an alkali while adding a diluent each time viscosity of the mixture is detected to rise. Apparatus for making the soap includes a sealed container 17 with compartments filled with the alkali and other additives, with the sealed container having protrusions 68 which engage switch elements 69 that control the amounts of each additive to be mixed with the fats. A tiltable baffle 78 feeds the grease added to the system alternately to one of two grease receptacles 75 or 76, a D.C. motor drives a mixer 55, and water from a water tank 30 is added to the mixture in response to the detection of an increase in voltage drawn by the motor.
