ABSTRACT:
Disclosed is a soap making split mold composed of a set of splits1A and1B adapted to be assembled together to form a molding cavity1C. The split1A has a larger surface area in its recess11A defining part of the cavity1C than the other split1B does in its recess11B defining the other part of the cavity1C. The ratio of the surface area of the recess11A of the split1A to that of the recess11B of the split1B ranges from 52:48 to 66:34. Otherwise, the split1A has a larger surface roughness Ra in its recess11A defining part of the cavity than the other split1B does in its recess11B defining the other part of the cavity. The difference of the surface roughness Ra between the recess11A and that of the recess11B is 0.1 to 30 μm.
