Slate Mantels

Cast Tec offer a range of two beautiful grey slate mantelpieces, the Hexham and Kensington.


Slate has been used in the manufacture of fireplaces for many years and being a particularly hard substance is ideal to be used as a mantelpiece or hearth. Slate tends to be shades of black, grey, blue and green, however our slate is similar in colouration to that of typical Welsh and Lakeland slate.


Our two slate mantel designs have shelf lengths of 1350mm (53″) and arrive with concealed fixing attachments. CastTec also offer matching hearths and stove inglenook infills for those requiring a slate suite to suit a wood burning stove installation.

About Sandstone:
Sandstone is a clastic sedimentary rock composed mainly of sand-sized mineral particles or rock fragments. Most sandstone is composed of quartz or feldspar because they are the most resistant minerals to weathering processes at the Earth's surface.

Like uncemented sand, sandstone may be any colour due to impurities within the minerals, but the most common colours are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colours of sandstone have been strongly identified with certain regions.

The formation of sandstone involves two principal stages.

First, a layer or layers of sand accumulates as the result of sedimentation, either from water (as in a stream, lake, or sea) or from air (as in a desert). Typically, sedimentation occurs by the sand settling out from suspension; i.e., ceasing to be rolled or bounced along the bottom of a body of water or ground surface (e.g., in a desert or erg).

Finally, once it has accumulated, the sand becomes sandstone when it is compacted by the pressure of overlying deposits and cemented by the precipitation of minerals within the pore spaces between sand grains.

The most common cementing materials are clay, silica and calcium carbonate.

Sandstone has been used for domestic construction and housewares since prehistoric times, and continues to be used today as a building material. It is relatively soft, making it easy to carve. It has been widely used around the world in constructing temples, homes, and other buildings. It has also been used for artistic purposes to create ornamental fountains, grindstones and statues.
