Lamps have been used in magico-religious systems much longer than candles, although candles are a lot more common now. Lamps are good for long-term spells, and once you have the materials they’re actually more economical than candles. Plus they can be “loaded” with appropriate items.
This is a lamp for protection of the family, so I used a blue mason jar. The fuel is canola oil (olive oil would also be appropriate here), and the wick is a length of rolled cotton bandaging. Inside is a whole angelica root, a chunk of dragon’s blood resin, and a cat’s eye shell–all strong protective items. They were all dressed with Peaceful Home Oil (and I added a few drops of it to the fuel oil) and smudged with sandalwood incense before being placed in the jar. Under the lamp is a petition paper; a family photo would also work.
You can use these lamps for virtually any purpose, just fill them with items appropriate to the purpose and make sure you use the right color. Apparently some people leave theirs perpetually lit, but I am way too paranoid for that. I light it when the sun goes down and pinch it out when I go to bed. (NEVER blow out a lamp, or a candle unless the spell is over–and usually you’re supposed to let them burn out. Blowing a flame out signifies the spell is over.)
