Expect a longer burn period with the offertory – straight candles because they are a little bigger than the small chime candles. The candle has ample surface area for you to engrave your intentions onto the surface, making it perfect for spells and rituals that need more time to function. Because they are the same size as the candle used during power outages, they are sometimes referred to as domestic candles. These are what some churches refer to as “congregational candles,” and they are frequently used for luminaries and candlelight vigils.
