Difference between quartz and granite
Quartz vs granite:
Quartz and granite are two materials which a e being popularly used as counter tops worldwide. They are both natural stones which are mined from beneath the soil and both are quite hardy because of which they are considered as ideal for flooring or to be used as worktops. And yet, quartz and granite are indeed two different materials which have their own strengths, weaknesses as well as qualities which define what they are.
What is quartz?
Quartz is considered as the most abundant material in the world which has a hard, glossy appearance that is quite appealing to the eye. It is made up of silicon dioxide in crystal form of which the crystalline qualities makes it a light reflective, semi-precious gemstone. It indicates a hardness of seven on the Mohs scale and thus is named as one of the hardest minerals in the world, next to the diamond. Raw quartz ranges from the size of rock salt to coarse grains which are then heated and vibro-compacted to form an impenetrable surface. This is the process which in more simple form includes raw quartz being mixed with pigments and resins which are then put in to molds, compressed, de-aired and vibrated. And yet, because of the fact that resins are involved in the production of quartz, it is not considered as being much resistant to burn marks as resin is known to be a heat responsive material.
What is granite?
Granite slabs are natural stones which are made up of a combination of quartz, mica and feldspar. It is a common coarse-grained, intrusive igneous rock which because of its natural crystalline texture, appears to glint in sunlight. However on the Mohs scale, granite can go up to a seven in hardness which depends upon the quantity of quartz that is included in the stone. It however, presents problems of radiation, issues of seam matching where different slabs are joined and also, granite needs to be annually sealed as well.
What is the difference between granite and quartz?
Granite and quartz are two natural material which are commonly used fro paving purposes as well as for counter tops worldwide. However, the qualities of these two stones differ quite significantly. For example, while quartz is considered as the world’s second hardest mineral which indicates a seven on the Mohs scale, the hardness of granite depends solely upon the amount of quartz that is found in the stone.
However, even though quartz tends to be much heavier, stronger and harder than granite, it tends to be more easier to cut and to shape than granite. This is due to the fact that granite tends to be quite brittle and of different textures in different regions, composed of more quartz in some areas than in others.
Quartz exists in the form of small crystals which then need to be processed in order to be made in to slabs whereas granite exists in the form of stone slabs. Quartz is made up of a combination of silicon dioxide, pigments and resins whereas granite is made up of quartz, mica and feldspar in varying quantities.
Because of the porous quality of granite, it needs to be annually sealed in order to prevent the breeding of bacteria or other harmful microorganism. Quartz on the other hand tends to be less porous due to the fact that it has already been sealed with resin. Granite also tends to change color as time goes on while quartz is known to retain its color for extended periods of time. However, if a quartz counter top gets damaged, one has to replace the piece entirely whereas in the case of granite, a surface polish could easily solve the issue of many chips and cracks that can occur during the course of time.
