Quick Answer
To store birch bark for long-term use, dry it thoroughly, cut it into thin strips, and store them in an airtight container with a silica gel packet to maintain low humidity. This will help preserve the bark's tinder properties.
Preparation and Drying
To store birch bark properly, it’s crucial to dry it thoroughly. Hang the birch bark strips in a warm, dry place with good airflow, ideally between 60-80°F (15-27°C) for 2-3 weeks. You can also speed up the drying process in a low-temperature oven (150-200°F or 65-90°C) for 2-3 hours, but be cautious not to overheat. Once dry, the bark strips should be brittle and crumbly, indicating they’re ready for storage.
Storage and Preservation
Cut the dried birch bark strips into smaller pieces, about 1-2 inches (2.5-5 cm) long and 1/8 inch (3 mm) thick. Store them in an airtight container, such as a glass jar or plastic container, to maintain low humidity. Include a silica gel packet or a small bag of desiccant to absorb any remaining moisture. Seal the container and store it in a cool, dark place, ideally between 40-60°F (4-15°C). Check the bark periodically to ensure it remains dry and crumbly.
