I would assume that was probably what is called pool fire. If you heat a candle enough, you can get its stearin to vaporize before it’s lit on fire. The vaporized stearin burns very hot, causing the rest of the stearin to vaporize even faster, meaning there will be more fire, etc.
That’s why you should never put many tealights next to each other. They can be very skilled in causing a pool fire. And looking at the photo of a lot of candles shoulder to shoulder to each other, one would assume from the photo that there will eventually be a pool fire. Especially since there’s a tent that can do a good job directing the oxygen flow.

What kind of candles are prone to this? Like, why make them out of that material at all? Beeswax candles don’t do that, as far as I know…
