Quartzites are typically the metamorphosed product of an original sedimentary rock e.g. sandstone, composed almost entirely of quartz. In general quartzites are hard wearing, have low porosity, a high compressive strength and good durability making them suitable for use as flooring. The metamorphic varieties in particular may be brittle and so some care is required in assessing a material prior to use. While composed largely of quartz, the presence of some impurities can lead to the development of different colours and the typical range is from white to yellowish brown, through to green, brown, gold, grey and blue. InEire, the metamorphic quartzites have a complex geological history which has tended to result in them having a relatively small natural block size. All operating quartzite quarries in the British Isles occur inEire. Elsewhere quartzites are commercially available fromNorway,Sweden,Italy,South Africa,USAandBrazil. Affordable Granite and Marble can supply quartz worktops in many colours including quartz black and quartz white.
