What Is Kindling Wood?
What kindling is, why it matters, and how it bridges the gap between a firelighter and a full-size log.
The short answer
Kindling is small, dry pieces of wood used to build a fire between a firelighter or tinder and the larger logs that keep it burning. Because each piece is thin, it has a lot of surface area relative to its size — that's what lets it catch quickly and burn hot enough to ignite thicker fuel.
Why you can't skip it
A firelighter alone rarely generates enough sustained heat to ignite a full log — the flame burns out before the log's surface gets hot enough to catch. Kindling closes that gap: it catches almost as easily as the firelighter itself, but burns for long enough, and with enough heat, to bring a small log up to its own ignition point.
Skip kindling and you'll often end up relighting a fire two or three times, or wasting firelighters trying to force a large log to catch directly.
What makes good kindling
Three things matter most: size (thin pieces catch faster), dryness (damp wood wastes heat evaporating moisture instead of burning), and consistency (a mix of sizes gives you control over how quickly the fire builds).
