Origins, Natural Resistances and Maintenance

There is little doubt that quartzite is of the toughest natural worktop surface choices

Naturally Tough

With a huge quartz content of over 90% and naturally durable and resistant due to its quartz content, Yes, quartzite worktops are tough. But despite its amazing natural resistances, it is not impervious and any extreme activity can and will mark the surface just like any other. It must be understood that all quartzites differences in appearances is due to all the minerals from the environment it was created and as a result the surface may vary in hardness and some areas or colours may mark easier than others. It is for this reason, sealing natural quartzite worktops periodically is essential for the longevity and upkeep of this material. Often mistaken by name for engineered quartz, and sometimes tougher marbles have seen mis-representations as quartzite, it is very important that you speak to an expert first to ensure that your quartzite worktop is in fact a quartzite.

Metamorphosed from Sandstone

SUMMARY: Quartzite is formed when Chert or Quartz Rich Sandstone is exposed to high temperatures and pressures. Through metamorphism, the quartz grains are fused together to form a dense, hard, equigranular Metamorphic Rock called Quartzite. To be classified as quartzite, a metamorphic rock must contain at least 80% quartz by volume. Quartzite appearances are determined through the metamorphism process and the minerals within its environment.

Diversity

The choice of quartzites, as a natural and quarried stone, is very diverse. Many are suitable for quartzite kitchen worktops, and colours vary substantially from one type to another. With appearances that can be best described as abstract paintings, some with vivid colouration, bright and pearlescent or gentle with linear veins. It is guaranteed that you will have a unique kitchen worktop for all to admire.

Material Sourcing

With the range of colours available varying substantially from each block cut from the quarry. It is advised projects requiring precise colour and pattern matching are quantized carefully so that ordered surfaces are cut from the same block. Check with us in advance to material source your preffered quartzite material, as stone suppliers stock levels vary from day to day to meet demands.

Resistances

Quartzite, alike all other natural stone materials is formed in extreme conditions and naturally resistant to heat and fading from sunlight and UV ray exposure. The denseness of this mineral rich stone, especially as highly polished surface, its porosity is low, making it resistant to staining from chemicals and acids. The high content of quartz crystal makes quartzite extremely hard and scratch resistant. Being almost twice as hard as glass and a mohs hardness of 7 to 8 (10 being that of diamond), it is harder than granite.

Support Bars

Quartzite is that tough, that when broken with force, the break will cut through the quartz crystals along the break line. It is for this reason that supports will be required to the front and back of cut-outs for sinks and hobs. Also, it is likely that veins and fissures within the quartzite worktop will cross the narrowed sections making weak points too.

Maintenance

Sealing

Sealing this material at least once a year will help maintain resistances to liquids. Quartzites with fissures along quartz rich veins provide higher risks, reccomendation is to seal these surfaces twice yearly. At mgm & Rocks Ltd we seal all quartzite surfaces before installation.

Protective Utensils

Despite a heat resistance in excess of 450 degrees Fahrenheit, the use of trivets and placemats are strongly recommended to reduce the risk of thermal shock from hot and cold pots, pans and plates. Habitual use of chopping boards will prevent mishaps and also contain troublesome juices when preparing food.

Cleaning

Quartzite worktops require little maintenance, its highly polished and sealed surfaces contributes to antibacterial and anti-mold aspects. Wiping the surface clean with a soft cloth and warm soapy water is all that is required to clean, for stubborn deposits, soak and repeat wiping.

Avoidance

Household cleaning chemicals and abrasives should be avoided as these only wear away the protective sealant layer. Calcium in tap water contributes to dulling worktop surfaces over a period of time, so wiping dry with a cloth will also prevent the build up of calcium desposts (Hard water) and keep your worktop shiny.

Products

Products that can be made from Quartzite are wide and varied, its hardness and suitability can be compared to granite in many ways. However, as quartzite consists of a substantially higher content of quartz, veining and natural fissures provide weak points. Without adequate support or if not fully bedded on floors, its liklehood to cracking is high
