This type of limestone is extracted in the heart of the Natural Park of Serras de Aire e Candeeiros, more specifically in Monsanto, Alcanena. Used for a long time cladding the walls of Portuguese houses, this type of limestone presents many positive characteristics. It can be easily confused with some kind of marble when polished, but it ends up having a very superior resistance considering its durability outdoors. In addition to presenting a notable resistance, the Alpinina limestone also integrates very characteristic colours such as: pinkish cream coloured background with strong white calcite lines and reddish fine grain veins.
Abrasive treatments with repeated applications result a shiny surface, highlights the color and properties of the natural stone.
Brushing the slab with a range of brushes and the result is a slightly undulating surface, very soft, warm and smooth to the touch.
Blasting silica sand against the material through an air gun and generates very small craters.
Hitting the material, with a masonry tool called a bush hammer, that generates uniformly distributed craters of different sizes over the surface of natural stone.
A honed finish is identical to the polished finish, the surface is smooth but without glare or light reflections.
Abrasive brushes under high pressure generate a touch-sensitive and smooth surface of natural stone.
Splitting stone either by hand or by machine so that the surface exhibits a natural quarry texture.
Scratched finish is applied so that the surface exhibits a texture with straight reliefs and natural colours.
Rough and irregular surface with small furrows and undulations in a mate tone.
