Let’s take a look together at the processes that are normally applied to a windowsill or a custom-made Natural Stone product in general.
We can choose different finishes based on materials including: shiny top, polished top, brushed top, saw/disk top, flamed top.
The choice of the type of workmanship on the sill depends essentially on personal taste, but it is good to say that shiny, polished or brushed surfaces are often used for interiors, while rougher finishes such as sawed or flamed are more suitable for exteriors.
Marble is generally chosen polished or shiny as the beauty of the marble is enhanced by the rub-up and even more by the polishing as it increases the contrasts of the veins present.
Some granites, on the other hand, look very good outdoors with the rougher finishes such as saw top or brushed.
