All functional ware is fired to stoneware temperatures of 1230-1240c. Literally this means that the ceramics turn to stone and therefore can withstand oven temperatures.
Treat as you would your present china ware and don't boil dry, hold over direct heat or plunge into cold water. I do place items in the dishwasher. However, I do not use the microwave as some glazes and clay bodies contain metallic oxides.
