These are used as decoration or maybe even serving boards. They are sealed with polyacrylic to keep nice (this is not with the food grade safe variety). They are NOT to be used on top of hot stove or oven. They are made of wood, so can be a fire hazard if you place on hot surface. Keep that in mind if you have a stove with the knobs on the front that could easily be turned on by pets or children by accident. They are also not to be used as a cutting board. You could potentially use as a large serving tray or placed over a sink when using stove. It’s important to have the stove and oven completely cool before placing back on.
