I bought some Mystic Water shaving soap and they recommend grating the puck. Then you load the flakes or small pieces back into the container, pushing down firmly to eliminate any gap between the soap and sides of the container. This makes sense to me, as I like to put hot water onto the top of the puck while my brush soaks in the bowl. Not having a gap between the soap and container will keep the water on top of the puck, allowing it to "bloom". And most pucks that come in containers are slightly smaller than the container. I tried it and I like it. Does anyone else here do this? I am new to making my own lather and any tips or tricks will be appreciated.
