An oven accessory is an item used to protect the user from heat when using an oven. Two common oven accessories are mitts and gloves. Mitts are four-letter items that are usually made of cloth or silicone and are designed to protect the user's hands from heat. Gloves are five-letter items that are usually made of cloth, leather, or silicone and are designed to cover the user's entire hand and arm for extra protection.
