Cumbria produces the best slate in Britain, from three mines, but only one mine produces slate with a golden thread. The mine with the golden thread is Kirkstone, whose genial proprietor, Nick Fecit, has kindly agreed to co-sponsor our Victorian Aviary Garden for Chelsea with the supply of the slate for the floor of our Aviary. The golden thread will marry well with the gold-leaf decoration of the Aviary. I spent the morning at the Kirkstone workshop at Skelwith Bridge choosing the slate which we will use. It was fascinating to see the processes used to produce the various slate finishes- from walling stone to polished worktops. This video shows Nick and some of his skilled craftsmen working on the slate.
