Just a simple melt and pour soap. I used a clear suspension base, orange oil, and ground up pistachio shells (this was a recycling project). At first I tried grinding them up in the food processor but it couldn't even touch them so I used my Vitamix, which survived but the shells did pit some of the surface of the plastic of the jug so be warned if you have a Vitamix and want to attempt grinding nut shells in it (really you're supposed to use the dry jug/blade but I didn't want to shell out another 125 bucks for a separate pitcher/blade). The idea was to make a bar a soap that could really clean grime off your hands. Haven't tried it yet but it was fun and simple to make.
