Oh, I haven’t used a chime candle since I was about 12 years old- when the chime candles we owned almost burned down the wooden holiday chime Mom bought in Bryant, Ohio. She was so thrilled with that thing and so disappointed to lose it.
I trust @starborn and her assessment of time for each candle.
I am low income. Yes, I reuse candles for different kinds of spells.
I think of it this way: if I only had one piece of rose quartz and needed it for a self care and a love spell, I’d still be working with my own heart. Even if I saved the crystal for years between spells, it is my intention that casts the spell, not the crystal. I am casting upon myself, using the crystal as a focal point for my mind. Candles work the same way, but get used up over time.
When I do a spell, I use my candles to represent the elements rather than the spell itself. The spell may draw energy from different directions, but I am the one who focuses the energy. The spell happens in my mind and heart.
Do you carve your candles for your spells? You may want to save carved candles for similar intentions, but I still think you can use them for separate spells.
Blessing candles with oil and intention is a tool of focus for the current spell. It can be cleansed with a new intention.
Please remember that the candle itself is a tool, not a cage or rule. You hold the intention and all the power.
Another possibility is to save the partially used candle until the spell manifests and light it to express gratitude.
If it were me, saving partial candles, I might end up with a drawer full of candle nubs with no clue which ones were for which spells- which means I’d forgotten the original intentions and could use the nubs for anything after all.
I began my practice using any candle I could get my hands on. The focal point was the flame, which was the energy source. Burning a 7 day or evening taper took a long time, so I did several spells on one candle on a regular basis. Once the flame was extinguished, the spell was sent out to the Universe for manifestation. Nothing unexpected ever happened from using a candle multiple times.
