When soft stone does not mean poor stone !
It can take a while for a layman to understand how sometimes it is not the harder stone that make the longest standing building ! Take clunch limestone from Bedfordshire, it has been used on so many churches in that area and there are still standing. Of course when you see a piece of lunch your first thought are,
how can such a soft stone stand weather and pollution ?! We have used this particular stone for centuries in France ! called tuffaut all the Loire valley is made of it. Trimmed every 100 years the limestone stone shed its new skin of Calcin every century.
This bright and white tracery mullion window are a treat to look at !
