The heat in the kiln dries off the resins in softwoods. Air-drying is a natural process that can take up to 8 -16 months, depending on the species of wood. Kiln-drying, on the other hand, usually takes 6 – 8 weeks. This process doesn’t introduce any internal tensions in the wood.
What temperature do you kiln dry wood?
Temperatures inside the kiln range from 120 to 190 degrees F, depending on the stage of drying. Although there are kilns in which temperatures reach up to 240 degrees F, they are usually limited to softwoods that dry very easily and low-value hardwoods.

This method is costly (though the space required is less).It requires skilled labor.Due to the process of drying is quick; continuous attention needs to be given to check seasoning defects such as warping, internal cracks, surface cracks, and end- splits.
Is kiln drying necessary?
Because the dimensions of wood products change with fluctuation in relative humidity, kiln drying becomes one of the most important processes for the efficient use of wood products. Proper machining, gluing and finishing of wood are not possible until moisture content is reduced to an appropriate amount.
How do you dry wood without a kiln?
Kiln Dried Wood
Without a kiln, you should try to achieve an air-dry moisture content of 15-20 percent. Further moisture reduction occurs when you move the boards indoors where they’ll eventually reach their equilibrium moisture content (EMC).
Can you dry wood in a pottery kiln?
No problem for the kiln, but it changes the wood some. As long as the furnace atmosphere can get out (the chimney is open), air circulation shouldn’t be an issue. Heating will drive the water out and unless it is a sealed or pressurized vessel, it won’t push back in.
