I was browsing the forum today, and came accross the "How to Mill any soap into a container ~ Photo Tutorial" thread, which I have used for reference in the past. But just reading the title today made me wonder; Instead of milling a tallow shaving stick into a bowl, can one take a tallow shaving soap puck, and mill that into a shaving stick-style container to make a shaving stick? Obviously one cannot melt a tallow soap, like a glycerin soap, so I was just wondering, is it possible? My worry would be whether the stick would be durable enough after such a procedure.
