Casserole purchased to heat the dishes of my baby as I do not have a microwave oven, it has done its use. Also ideal for cooking 1 or 2 hard boiled eggs. Rather surprised at the quality for the price, the bottom is thick, resistant sleeve, shows no sign of wear despite daily use for several months (and washing in the dishwasher). So glad I bought 2 sizes above me to form a series of small handy pots.
