Quartz stone is tough but not totally industructable. It is, still, highly resistant against rupture, abrasion and scratch. Like any other surface, Quartz stone can be permanently damaged by exposure to very strong chemicals and solvents, thermal shock, excess load or impact that weaken its physical properties. Therefore, pay due attention in order to let Quartz stone maintain its brand-new look for long years and never forget to use cutting-board and trivet.
Quartz surfaces are available in hundreds of different colours. The concrete range offers a unique leather finish. This hard-wearing surface is lighter than granite and easy to work with.
