Ravendale is without doubt one of the most interesting stones
on the market, offering excellent availability and value for
money, with an appearance similar to old Welsh blue black
slate.
Ravendale is completely free from Iron Pyrites and requires
the minimum of grading due to its consistency of thickness.
Ravendale slate will give many years of trouble free service.
|
| Ravendale
is almost unique in appearance with a blue/black colour and
non grainy slightly riven surface, a sedimentary stone with an
attractive edge detail. |
