So I got a Georgetown Pottery G12 Scuttle Mug. I really want to like it but I have been having issues. Every shave I have had with it has been terrible...I have a great shave every time I don’t use it. I think the heat from the scuttle mug makes the lather really light and airy. The lather dissipates extremely quickly and offers no protection. Is this normal with the heat from a scuttle mug?
