I fashion it into a shave stick.
Curious, do you grate or melt, and how do you form it?
I have tried a couple VDH experiments. The addition of Old Spice cologne went well, and was just a nuke, add and stir affair.
I was gifted a puck of Burt's Bees Bay Rum soap. For those of you who don't know about this soul-sucking, nasty, deceitful and demoralizing abomination parading about as shaving soap, let me describe it.
It has a wonderful, intoxicating Bay Rum scent that acts as a siren song, luring you close enough to be driven to gibbering insanity by it's inability to lather, or even produce a film that could be useful for shaving. Imagine that sadistic killer bees made a hive out of old congealed oatmeal and infused it with waxy hardness, and then lured prey close enough for the kill with a nice Bay Rum aroma.
I decided to fix this by adding VDH. I melted my portion of VDH, and then made the critical error of putting the Burt's Bees Slice O' Hell Marketed as Soap in the microwave...It burned and releases a noxious, choking cloud that is hard to describe. Let's just say that when I was able to return to the kitchen hours later, I found the floor littered with cockroaches, tiny pistols still clutched in their claws, brains blown out and noses pinched shut.
There are some things that mortal man is not meant to mess with.
