A dense, fine-grained metamorphic
rock, slate was formed when ancient seabeds, filled
with sediments of clay and shale, were pushed upwards
by collisions between the continents. It is an extremely
durable tile whose beautiful color variations indicate
the presence of minerals such as iron oxide. All
slate exhibits clear clefting along parallel planes
which gives it a unique, streaming texture –
a wonderful touch in even the finest of homes.
