Altar candles are tall, thin candles made of beeswax and stearine. They are topped with a brass or glass candle follower, which helps keep wax from spilling on the altar linens. Altar candles are lit using a taper, which is a lit wick attached to a long handle. They are lit and extinguished in a particular order so that the Gospel side candle is never burning alone. The Gospel side of the church is the left side as you are facing the front. So the candles are lit from right to left and extinguished from left to right.
