After setting the heat, place one kitchen rack on the bottom and another in the center. Now, place a large baking pan on the bottom rack and put an oven thermometer onto the center rack in one of its far corners. If your oven doesn’t let you set the temperature to 217 °F (103 °C), set it to the closest increment, such as 215 °F (102 °C). Monitor your oven thermometer every 10 minutes. If it's too high, lower the temperature, and if it's too low, increase it. Always adjust the temperature by the smallest increments for optimal accuracy. Turn on your kitchen fan if it has one—this will ensure optimal airflow. Be sure that none of the pieces are touching. For smaller pieces, lay them perpendicular to each rung of the oven rack to prevent them from falling through. Continue monitoring the oven thermometer every 10 to 15 minutes and adjust temperature accordingly. After 1 hour has passed, remove 2 to 3 wood pieces of varying sizes from the oven. Measure their moisture content using a moisture meter. Continue heating the pieces for 15-minute intervals until the desired MC or until the moisture levels do not decrease anymore. Purchase moisture meters from home hardware stores and online suppliers.
Preheat your oven to 217 °F (103 °C) and monitor its temperature. Adjust your oven settings until it hits 217 °F (103 °C). Place your wood onto the center rack for 1 hour. Test your wood's moisture content (MC) after 1 hour and reheat for 15 minutes increments as necessary.
