Will putting wet wood on a bed of coals in stove create creosote chimney?

Yes, putting wet wood on a bed of coals in a stove can create a creosote chimney.

When you burn wet wood, it produces more water vapor than dry wood. This water vapor condenses on the cooler surfaces of the chimney, forming creosote. Creosote is a highly flammable substance that can cause chimney fires.

In addition, wet wood burns at a lower temperature than dry wood. This can cause the smoke to condense on the walls of the chimney, forming creosote.

To avoid creosote buildup, it is important to burn only dry wood in your stove. You should also make sure that the chimney is properly insulated and that there is good airflow.
