Okay, so I hit my shave soap with my hand mixer yesterday, and it became a much smoother paste, and as of today it hasn't separated. Still trying to decide how to package this stuff up. It's very thick, but it's not as dry as I thought it would be, so pucks are out of the question. (I'll tweak the water amount next time to see if I can get it to form pucks!)
In the meantime... I currently have three options. I have empty deodorant/lotion bar tubes (not previously used!). I'm going to put some in a couple of those for sure, not sure if I'm going to do more than that. Today I purchased some wide-mouth pint jars and plastic wide-mouth lids, as well as four ramekins. I'm debating between them... For reference, none of my friends who shave currently use shaving soap, so they don't have brushes.
