*To make long rectangles
of soap that can be sliced, you can do this same technique using long
rectangular trays or drawer liners manufactured by Rubbermaid. Once
the soap is cooled remove from the mold and cut into 1" slices. If
you find that your soap crumbles when cutting, chances are it is too
cold. Be sure it is at room temperature before slicing into bars.
If transparent soap pieces
breakaway from the white soap, the white soap was probably too cold
when it was poured over the transparent. Do not freeze the
transparent soap pieces before pouring the white soap base over them.
Also, if you find that
your transparent soap pieces were melted when the white was poured
over them, the white soap base was too warm.
