I was bored and thought bad to a few weeks ago when I had said something on the 30 day thread about lathering Lava bar soap. So I decided that today was the day. I didn't want to use a brush I liked because I am sure pumice is bad for the hairs so I pulled out the new to me mystery brush I pulled out of the Nationwide box tour box. It feels like boar but it sheds more then I can accept and it kinda thin and overly stiff. I thought that lathering just Lava would be boring so I lathered up Proraso White, Modern Williams, and the lava. All three latherings used the same brush and mug and they were all loaded for 30 seconds. Pictures were taken 10 minutes after lathering was complete. So proraso first. I managed as good as ever with the proraso. A good solid lather that felt good between the fingers. I've always gotten decent lather from Williams. This was as good as the Proraso. Even in lasting power. Lava lathered better then I thought. It feels good between the fingers and is rich and creamy. However, within minutes I started getting bubbly and breaking down. In a pinch you could use it but why bother? It would ruin brushes and dull blades. Might be fun to try with a disposable at less once just for giggles.
