Is fatwood suitable for long-term storage and usage?

April 5, 2026

Quick Answer

Fatwood is suitable for short-term storage but not long-term due to its high moisture content, making it susceptible to mold and decay. This affects its usability and reliability in fire starting.

Characteristics of Fatwood

Fatwood is a type of wood resin that’s often used as a fire starter. It’s high in sap and pitch, making it highly flammable. However, this also contributes to its short shelf life. When exposed to air, fatwood naturally dries out, but its high moisture content when harvested makes it prone to mold and decay. This can lead to a loss of its flammability and effectiveness as a fire starter.

Storage and Handling Techniques

To prolong the usability of fatwood, it’s essential to store it in a dry environment. This can be achieved by keeping it in airtight containers or plastic bags, which should be sealed to prevent moisture from entering. The storage area should be cool and dry, with a temperature range between 40°F to 60°F (4°C to 15°C). It’s also crucial to keep fatwood away from direct sunlight, as this can cause it to dry out too quickly.

Identification and Sourcing

To identify suitable fatwood, look for pieces that are high in sap and pitch. These tend to be the most flammable and effective. When sourcing fatwood, choose logs that are already decaying or have visible signs of sap flow. These will be more likely to contain the resinous material needed for fire starting. When cutting fatwood from logs, use a sharp knife or saw to minimize damage and prevent the wood from becoming too brittle.
