Church candles, also known as altar candles or sanctuary candles, are tall, thin candles used in religious ceremonies. They are typically made of beeswax and come in a variety of sizes. The term 'church candles' is often used to refer to the tapers, which are the tallest and thinnest type of candle used in churches. Tapers are usually about 12 inches long and have a diameter of 1/2 inch or less. They are used to light the way for processions, to symbolize the presence of God, and to provide a source of light during worship services.
