Quartz
For those who love the look of granite but are wanting an exact pattern, colour or something different quartz could be the answer. Quartz is the most common mineral found on the earth’s surface. It is present in nearly every geological environment and is a component of almost every rock type. It exists in an impressive range of varieties and colours. it ranks 7.0 on Moh’s Hardness Scale, which is used to measure the scratch-resistance of a material. Only the diamond (at 10), topaz and sapphire (at 9) are harder than quartz. Quartz does not form in huge stone blocks like granite does. It grows in clusters and which contain 40% – 60% quartz, limestone or other types of rock, it is not suitable in its natural state to make into countertops or other large slabs.
A process was developed and patented by an Italian company which involved using raw quartz crystals ranging in size from coarse grains to the size of rock salt. Once the quartz is ground and selected, the crystals are combined with bonding agents, resin, and colour, then heated and vibro-compacted to form an impenetrable surface. The result is a slab made up of about 93 percent quartz and 7 percent resin binders and pigments. Making it free of fissures and cracks and impervious to water, moisture and bacteria.
The appearance of the quartz surface varies depending on the size and mix of the granules. Smaller, finer crystals give a more uniform appearance, while larger ones give a more mottled look. The colours that quartz are available in also vary as pigment can be added. Most of these colours can suit modern design but can’t be found in nature! Quartz is ideal for use in countertops, flooring, shower and tub enclosures, fireplace surrounds and furniture.
