n the article pH values of wood and their influence on processing and usage of different woods are discusssed. Wood species mostly show low pH values, which are results of extracting organic acids, mainly acetic acid. At unappropriate air moisture and temperature extracting is even more vigorously.
Woods with low pH values are the cause for metal corrosion, make glueing and finishing difficult, cause color stains and assure adequate conditions for fungi attack.
