A unique controlled process The Stellac Thermal Wood Modification technology consists of a 5-step process. During each stage, your raw material is monitored and protected, and the fully automated process control system ensures that the end-product meets your requirements and expectations: high-quality products, maximized yield and consistency of color.
Peparation. During the Initial Heating(1) and Preconditioning & Drying(2) phases, Stellac brings the temperature above water boiling point, preparing your wood for Thermal Modification. To ensure successful results without defects such as checks, your wood is dried in a gentle and accurately controlled environment.
Modifying your wood. As your wood as been relaxed by eliminating internal stresses during the Preconditioning & Drying phase, we are now ready for Thermal Modification(3). Depending on the final application and your requirements, the kiln temperature will be raised to up to 250 C (482 F) (Picture of different colors)
Relaxation. As your wood has been exposed to harsh temperatures, it needs to be relaxed carefully in order to avoid splitting and other defects. During the Conditioning(4) phase, the correct moisture level is restored, appropriate to the final application of the wood. Before being removed and further processed, the timber is taken through the gentle Cool Down(5) phase, in order to ensure a long-lasting, high-quality end product.
