This past weekend I purchased a puck of shaving soap made from a small soap vendor. She described how it had been formulated, and I thought I would give it a try. When I read through the list of ingredients I realized it was missing one of two critical components Glycerin or a Tallow product. It had clay in it. It was slick and smelled good but unfortunately it didn't have any cushion when lathered. I tried multiple times hand lathering to get it to work; still no dice. It also had sugar in it which my wife told is used to aid in exfoliating, hopefully my brush wasn't damaged. Now it will become an expensive shower soap. The lesson, read the label if your not buying a well known brand.
