vääntymiset
Vääntymiset, a Finnish term, refers to the twisting or warping of materials, particularly wood, during the drying process. This phenomenon is a natural consequence of uneven moisture loss within the material. As wood dries, its internal structure shrinks. If this shrinkage occurs at different rates in different parts of the wood, or if the wood is exposed to varying environmental conditions, internal stresses build up. These stresses then manifest as visible distortions, such as cupping, bowing, or twisting.
Several factors influence the degree of vääntymiset. The type of wood, its grain orientation, the initial moisture
While vääntymiset cannot always be entirely prevented, certain practices can minimize its occurrence. Air-drying wood slowly
