A candle mold is a specialized container used in candle-making to shape melted wax as it cools and solidifies. Made from materials like silicone or metal, molds come in various shapes – from classic pillars to intricate designs. The mold holds the wick in place while the wax sets, ensuring the candle retains its desired shape. Once cooled, the mold is removed, revealing a beautifully crafted candle ready for use or decoration.
