<human>: Here is a goal: How to heat coals for a charcoal fire?

How would you accomplish this goal?

OPTIONS:
- Once you have sufficient embers on your wood, remove the wood with a stick and lay fresh coals against some new wood, light it until they turn and glow red
- Once you have sufficient embers on your wood, chip away at the wood with a stick and lay fresh coals and more wood against the broken embers until they turn and glow red
