THE EXPERT S OPINION
Among your quartzite varieties, are there any that are well suited for distinctive forms of use? Based on their colouring, almost all quartzite varieties are well suited for cladding solutions, kitchen tops and the furnishing sector in general.
Which is the most sought out among these quartzite varieties? Taj Mahal quartzite: thanks to its veined ivory colour, this stone resembles high quality marble, but is actually even more resistant.
What are the aesthetic and structural characteristics of quartzite? Quartzite is a metamorphic stone, largely consisting of quartz - approximately 70-80% - plus calcium carbonate, feldspar and mica. The variable percentage of these components is what gives the material its colour. The higher the quartz concentration, the more transparent or translucent the quartzite.
Where do the Marmi Lanza quartzite varieties come from? Quartzite can be found in every continent. The best-suited
specimens for slab processing are the Brazilian ones.
How are quartzite blocks extracted? The blocks are extracted either from mountain quarries or from boulders, i.e. large isolated rocky elements. Usually, once the bank is identified, it is then cut into blocks. We are typically looking at a time frame between one week and 10 days between the sectioning of the bank and the cutting of the blocks. The banks can be quite imposing, reaching sizes of up to 20- 30 metres in length and 3 metres in thickness.
