With our recent lectures in materiality trip back home to Norfolk this weekend enlightened me to the fact that Norfolk is not a county rich in hard rock, although there is plenty sand, stone, gravel and carrstone.
A circular walk around Wolferton and Sandringham is filled with 'gingerbread' houses and carrstone detailing, encouraging myself to expand my knowledge.
Carrstone (aka gingerbread, silsoe, heathstone or ironstone) is a sedimentary sandstone formed during the, Cretaceous period (beginning 145 million years ago ending 66 million years ago). Carrstone is a relatively soft rock, typically used as a building stone extensively in historic buildings of northwest Norfolk. Carrstone can also be phased into puddingstone, ferricrete and silver carr. Below are examples of ashlared carrstone.
Below is clay brick archway, with sandstone capping and centre piece and carrstone detailing. The carrstone here is it rustic and random on each wall whilst the carrstone above is asharled and laid in courses.
The carrstone below is a strong example of true gingerbread coloured carrstone with brick quoins, protecting the carrstone from wear and providing additional detailing. This is taken opposite Wolferton's disused railway station.
Below is a strong example of the variety of colours of carrstone (along with some brick and other filled stones!).
