What I like to do in the winter months is take my ceramic bowl and with tap running on hot water just turn it upside down with soap inside and soak the heat into the ceramic bowl for a least 20 seconds and then start to make the lather. Making the lather first and then heating the bowl does not work very well from my experience when testing years ago.As a further commitment towards this method, I just bought a G20 GP scuttle. One thing about this method I didn't like was cold lather. I've been wanting to try a scuttle for years anyway, just needed a little push.
The heat from the bowl raises the temperature of the lather nicely and when applying it gives a warm feeling. With the mister you could still heat the bowl and use warm water( some of fancy atomizers use a bladder & with hot water can damage the mister is my understanding) and try that method.
I take SOTD photo and I lose a a few minutes of time, but the lather is still warm usually and is a treat for my shave!
A scuttle would work better and give a person time to do other things while getting ready for your shave.
(This is a old archive photo I took years ago on the benefits of using porcelain or ceramic bowls, they retain heat longer than plastic bowls IMO.)
Have some great shaves!
