A candle is a source of light made from wax or similar materials, containing a wick that is lit to produce a gentle flame. Beyond illumination, candles are often used for decoration, fragrance, and creating a warm, calming atmosphere. Available in various shapes, sizes, and scents, they can be simple and functional or ornate and decorative. Candles are commonly used for celebrations, religious ceremonies, relaxation, romantic settings, or home décor, making them both practical and aesthetically pleasing.
