Solid slate slabs or slate tiles for fireplaces are cut to size and supplied and installed by Scarlett Fireplaces in various sizes, shapes and thickness to suit your design requirements. Slate hearth finishes are either polished for a smooth surface, natural for a authentic finish or riven for a uniformed textured surface. Slate can withstand high temperatures found in fireplaces but must be installed as sections near hot wood fires to allow for expansion. Polished smooth slate, popular with gas fires, isn't very practical when used with a real working solid fuel fire because the polished surface scratches easily. It is best to oil slate hearths to protect the finished surface.
