: what do people mean when they say candles have “burn-memory”

43 viewsChemistryOther

So this often comes up when I see people talking about how their candles go fast. There tends to be a comment mentioning that it’s because of “burn memory” meaning that the FIRST time you light the candle, if it’s blown out too soon (before the melted wax reaches the edges of jar), then from there on it might not melt to the edges of the container ever again and will continue to tunnel downward every time you light it. I guess I know what they’re describing, but this makes zero sense to me. When you go to light it at a later time….how would the candle know and why not just continue melting outward 😩
