Quick Answer
Assess dryness of wood by looking for cracks, splits, and a light weight, and by performing a simple scratch test to check for sap and moisture content.
Preparing to Assess Wood Dryness
When assessing the dryness of wood for a fire, it’s essential to look for visual cues. Check for cracks, splits, or checks in the wood, especially on the surface and along the grain. Wood that is too green or wet will not have these signs. A dry log will typically feel light for its size, with a weight that is significantly less than a similar-sized wet log. For example, a dry log weighing 8 pounds may be a sign of good dryness.
The Scratch Test
Performing a simple scratch test can also help determine the dryness of the wood. Lightly scratch the surface of the wood with your fingernail or a sharp knife. If the wood is dry, the scratch will be a clean, smooth line. If the wood is moist, the scratch will be cloudy or white. Additionally, if you notice any sap or resin oozing from the scratch, it’s a sign that the wood is too green for a fire. Aim for a moisture content of 20% or lower for optimal firewood.
Final Checks and Preparation
Once you’ve assessed the dryness of the wood, perform a quick inspection for any signs of mold, mildew, or insect damage. Remove any debris or leaves from the surface of the wood, and split it into manageable pieces for easier burning. For a fire challenge, like the one-match challenge, having a single piece of dry, well-seasoned wood will give you the best chance of success.
