I have been on a mission to find the best way to make warm lather as well as to make it last for three passes. I started with a wood bowl and a candle warmer results were not good. The lather was to dry due to the bowl getting too hot. I used other bowls with similar results, until I came across a bowl made from soap stone. The soap stone bowl was able to hold the heat for a long time without drying the lather. In the picture below it is the bowl on the right of my shave den picture. I purchased the bowl at Walmart in the scented oil and candle section section for about $4.00 it make great lather as well.
