What is lightered knot?

Lightered knot is a type of wood found in the heartwood of longleaf pine trees and is also known as fatwood. It is highly resinous and has a unique aroma that is often used for fire starting. The wood is filled with resin that makes it highly combustible even when wet, and it burns extremely hot and fast. It is commonly used as a natural fire starter, for lighting campfires, barbecues, and fireplaces, and also as an essential oil in perfumes and aromatherapy products. Because of its high resin content, lightered knot is also sought after by woodworkers for its unique grain patterns and durability.
