What exactly causes foam or air bubbles in lather. It seems lots of times when I palm or do a test bowl lather that when I squeeze the brush out of lather and run it between my index and thumb and then pull it apart so to speak to see if it separates there is a foam look, instead of a solid clump of lather. A lot of times if I try and bowl lather using an old spice mug the lather will look great, but then in some parts where I stick the brush down and pull it up it’s as if there is a foam looking hole that separates instead of just like a solid clump of lather which I suspect it should be. Anyone every experience this? To much water, not enough water? It’s as if it looks great but then when i do these two things I know something is wrong.
