What are the effects of humidity fluctuations on the joints of pine sculptures?
Humidity fluctuations can significantly impact pine sculptures, particularly their joints. Pine, being a porous wood, absorbs and releases moisture with changes in environmental humidity. This expansion and contraction stress the joints, leading to warping, cracking, or even complete separation over time. High humidity may cause swelling and adhesive failure, while low humidity can result in shrinkage and brittleness. To preserve pine sculptures, maintaining stable humidity levels (ideally 40-60% RH) is crucial. Protective coatings and proper storage can also mitigate damage. Understanding these effects helps artists and collectors safeguard their wooden artworks from long-term deterioration.
