What does "a 4-inch candle" mean ?
Is that the length of the candle or its diameter ?
The life of a candle depends on its length, its diameter, the
thickness and starting-length of its wick, the exact substance
of which it's composed ... the type of wax ... and the motions
of the air around it.
I'll always remember the candle shop I visited ... I don't remember
what I was doing in a candle shop, but I was there. There was a
little wax turkey up on a glass shelf, with a tiny tiny flame in the
middle of its back, so tiny that you could easily miss noticing it.
The little sign standing next to the little turkey on the shelf explained
that this was a Thanksgiving candle ... it was lit last Thanksgiving,
and would continue burning until NEXT Thanksgiving, roughly a year later !
