Quartz and Granite, what's the difference?
Article by Steven Tyler.
What is Granite?
Granite is formed in the ground by the fusion of 3 natural minerals: Feldspar, Quartz and Mica. These minerals occur in different proportions and it is this that gives each slab of granite its own colour, texture and unique characteristics.
The advantages of Granite:
- 100% natural
- Tough and durable
- Markings in the stone are unique
- Many manufactures will let you choose which slab your worktops are cut from, ensuring a consistent quality
The disadvantages of Granite:
- It is porous, therefore susceptible to staining
- Needs to be sealed annually to prevent staining
- No suitable for use in kosher kitchens due to porosity
- Not as durable or heat resistant as Quartz
- Comes in a limited range of colours
What is Quartz
Quartz worktops are a semi natural man made product. They are made is made by mixing the natural mineral quartz with various resins, polymers and pigments. The ratio of these ingredients is approximately 90% quartz to 10% resins, polymers and pigments
The most popular brands of Quartz are Silestone, Caesarstone, Cambria, Compac, Unistone and Cimistone.
The advantages of Quartz:
- More durable and heat resistant than granite
- 100% non porous, so it's almost impossible to stain and is suitable for kosher kitchens
- Available in an almost unlimited choice of colours and finishes
- Never has to be sealed like Granite
The disadvantages of Quartz:
- It is not 100% natural like granite
- Perceived by some people as being characterless due to the consistency of markings
- Unlike granite there's no point in choosing your exact slab as all slabs will look identical
- Can vary in quality dependent on the brand chosen
