Vessels for heating milk as well as storing it without damage in kitchen

I heat milk twice in a day: morning and evening and keep them in the kitchen room only for at least a day.

While preparing the lunch or breakfast I’m facing difficulty to keep track of the milk because any small amount of addition of other substances may make the milk break down. I generally use a steel container and cover it with a steel vessel. The problem is not solving because once or some other time milk is getting damaged while adjusting vessels.

I’m thinking of any vessel that we can use for both heating and storing in the kitchen room only without any damage can solve my problem. I don’t want to replace milk to some other place etc.,

Are there any such vessels?
