Why does my furniture have cracks on the ends/is cracking?

All hardwoods lose their minerals and salts and as they evaporate cracks will appear on the end grain (tops of chairs/end of tables/end of arms). This is normal. Sometimes the crack will open quite wide, especially in hot weather. They will close when it rains or is cooler. This cracking will not affect the stability of the furniture and in most cases occurs within the first few months and gets no worse. Treatment can help reduce cracking as our Timber Protector replaces some of the natural oil that is lost through evaporation.
