Not sure about others but I was assured by GP that my scuttle was microwave, dishwasher, and oven safe...as long as I didn't heat it up above 500 degrees. I "nuke" mine because it's faster and more convenient than boiling water on the stove. You have to be careful though because if you use it right away it's too hot and will either dry out or make it impossible to make decent lather...and if you fill the outer bowl too full and it boils it will do the geyser thing in the microwave.

After many years of shaving with lukewarm lather I'm really liking what the scuttle can do for me.
