Wax candles are solid blocks of wax that are designed to burn slowly, providing light and fragrance. They are typically made from materials like paraffin, beeswax, or soy wax. When a wick is lit, the heat melts the wax around it, creating a pool of liquid wax that fuels the flame. These candles come in various shapes, sizes, and colors, making them popular for decoration and ambiance. Many people use wax candles during celebrations, religious ceremonies, or simply to create a cozy atmosphere at home. They can also be scented, enhancing the overall experience with pleasant aromas.
