If a ceramic dish says it's microwave safe then can I put it in the oven?
They are all made from welded tubingA solid piece of metal wouldn't be as strong and would be much heavier
Most handmade pottery can be used in the oven, however, with ceramics (porcelain, stoneware, or earthenware) you need to worry about thermal shockIt you take a piece from a cold refrigerator and put it into an already hot oven, or if you take a piece from a hot oven and put it on a cold counter, then you may have cracking due to thermal shockFor heating in the oven you need to put the piece in a cold oven and heat up slowly for best resultsThere is a special clay that is used for flamewareThis is a high thermal shock resistant clay body with a large amount of grog for pieces used on top of the stove that can take direct heatHopefully a label will say oven proof as well as microwave safe and dish washer safe, because heating in an oven is very different than heating in a microwaveSo be very careful if you choose to try your piece in the oven.
