Wood burning is the process of using fire to convert wood into heat and light. This method has been used for thousands of years for cooking, heating homes, and providing illumination. When wood is burned, it undergoes a chemical reaction called combustion, releasing energy in the form of heat and producing byproducts like ash, smoke, and gases. In modern times, wood burning can be done in various ways, including using fireplaces, wood stoves, and fire pits. While it is a renewable energy source, it is important to use seasoned wood to minimize smoke and pollutants. Proper ventilation and maintenance are essential for safe wood burning practices.
