One of the attractions of natural building stone is the wide variety of colours and textures available to the designer. However, such a wide range can also present a problem : how do you know which is the besst stone for the job? The variability of stone is not restricted to colour and texture. Wide variations in durability and other properties may also be encountered. Some stones may be unaffected by centuries of exposure to the weather; others, if used in the wrong environment, may have to be replaced after only a few years. Unlike colour and texture, durability is difficult to define and even more difficult to measure. This Digest summarises tests that can be applied to natural building stone. It replaces Digest 269 which is now withdrawn.
