CORROSION RESEARCH ROUND‐UP

METAL IN WOOD Corrosion of metal in wooden casings. Certain woods (e.g. beech and oak) contain up to 5% combined acid, mainly acetic acid. During furnace drying and steam treatment, a considerable quantity of acetic acid is released which, being volatile, is liable to promote corrosion through the gaseous phase. The dependence of this acid separation on the external conditions and the escape of the acid from the wood during storage have been investigated.
