A:AnswerI have no problems with chipping that is why i picked the copper one on the advice from you tube, when you pour coffee or tea do not use a metal spoon in the cup.I have had the cup for a month now with no problems and no it does not feel ceramic. Wash by hand and completely dry it before putting it on charger.
A:AnswerThe lid from Target’s $3 Room Essentials 10 oz coffee cup fits this perfectly. I use them regularly because it helps maintain the temp therefore preserving battery life and keeps my beverage from being exposed
A:AnswerWould depend on the Temperature setting you use and your own sensitivity.
I use the default 135 degree F setting with Coffee and Tea and the surface of rim is not too hot when drinking. The handle is still practically cool to touch.
The Ember mug only goes to 145 degrees F
