I really struggled with these soaps for a while, so much so that I sold my first batch off. Then when I saw them on sale at The Stray Whisker I decided to try again. I have seen the above video before, but for me this didn't work. Here's what I do, and again for me I have found that a synth works better than animal hair. Maybe this will work for you to, but if not, do not give up as when dialed in they produce a superb lather.
- soak the puck with a little bit of water
- after a minute tip the water into my lather bowl
- dip the synth into this water
- load the brush heavily, I'm talking about 30 - 45 seconds, at least, with a good amount of pressure. This is where I differ from the video, I overload. Again, this has worked for me.
- start lathering in the bowl adding water slowly
- After about a minute or so you should be getting a soft marshmallowy type lather. This is where I stop, I find that if I add more water now it becomes too wet.
- rinse my face with water leaving a thin layer to build on.
Using the above technique has given me some superb lathers.
