Drying Bark Slips in a Solar Kiln

Solar drying preserves the natural oils in the bark and prevents the paper from warping during the process.

Constructing the Solar Rack

• Use reflective aluminum sheeting to direct heat towards the paper rather than allowing it to escape.
• Construct a frame that allows for air circulation on all sides to prevent moisture buildup.
• Install a clear acrylic sheet on top to trap solar energy and maintain a consistent temperature.

Monitoring the Drying Cycle

• Check the humidity levels inside the kiln every two hours to ensure proper airflow.
• Rotate the sheets ninety degrees halfway through the drying process to ensure even results.
• Cover the rack immediately if the ambient temperature drops significantly to avoid condensation.

Proper drying is essential to prevent mold growth and maintain the structural integrity of the bark paper.
