Im wanting to do a bit of cooking on top of the stove, and have a water tin on it to put moisture back into the air. I dont wanna mess up my nice new stove, is there something i should put down like a fireproof pad, or a little stand to keep from messing up the nice stove metal, and to keep the food and water from getting too hot? im sure that i dont want the water to be boiling to get moisture in the air.
