Quick Answer
Bark cordage can last for approximately 1-3 years in storage when properly dried and maintained, but its durability and lifespan depend on various factors, including storage conditions, handling, and the type of bark used.
Types of Bark Suitable for Cordage
When it comes to selecting bark for cordage, different types are more suitable for storage and use than others. For instance, cedar, cypress, and redwood bark are known to be durable and resistant to rot, making them ideal choices for long-term storage. On the other hand, softwoods like pine and fir tend to be less durable and more prone to decay.
Drying and Storage Techniques
To extend the lifespan of bark cordage in storage, it’s essential to dry the cord thoroughly before storing. This involves hanging the cord in a cool, dry place or using a desiccant to remove excess moisture. When storing, wrap the cord in a breathable material like paper or cloth to prevent moisture buildup. Store the cord in an airtight container, such as a plastic bag or airtight container, to protect it from dust, dirt, and pests. The ideal storage conditions for bark cordage are a temperature range of 40°F to 60°F (4°C to 15°C) and humidity levels below 50%.
Testing the Durability of Stored Cordage
To evaluate the condition of stored bark cordage, perform a simple tensile strength test. Cut a length of cord and attach it to a surface using a knot. Then, apply a gentle tension to the cord, slowly increasing the force until the cord breaks. Measure the breaking strength and compare it to the original breaking strength. If the breaking strength has decreased significantly, it may be time to replace the cord with a fresh one.
