All these products are food and liquid safe, and can go in your microwave and oven. However, they are delicate and if not cared for over time they will show signs of wear.
To look after your pieces I recommend handwashing, and reducing exposure to temperature shock.
(Essentially don't take a hot dish out of the oven and put it on a cold stone countertop and don't put a cold dish from the freezer into a hot oven).
