For those of you who are having a hard time with the lather, or whose lather with this puck is different from your normal Williams lather, let me reiterate something....
This is normal! We are doing this as an experiment, and as sometign different form the norm, just to have a little fun..... however, the addition of aftershave to the puck will, the vast majority of the time, affect the lather in a negative way. If all the alcohol doesn't burn off, that's definitely going to affect that, but unless your soap is soupy or soft, It's probably gone. However, there's other ingredient in the AS, that are probably affecting the lather as well. One thing I did say before was to try to pick an AS that had a good glycerine content, or to add glycerine to it to help combat this. When I did this a few years ago, I used Aqua Velva Original Sport (the green stuff from Canada). It's marketed as a cologne and not an AS, and doen't have as much (or any, I can't remember), but the lathers I got form that puck were horrible. I experienced the dissipating lather that a lot of you are experiencing.
Next time, try to add a drop of glycerin to your puck or bowl before you lather and see if that helps.
