Nero Assoluto
The close-up view of each stone type shows a relatively true image of the crystalline structure and the colouring. This is suitable for grained slabs to a limited extend only. In regard to the colour matching, please take an original sample of the stone from your furniture store as a basis.
Petrography
Fine-crystalline, dense and very homogeneous plutonic rock belonging to the darkest natural rocks. Nero Assoluto consists of a uniform mixture of black pyroxene minerals, colourless plagioclase feldspar and black-grey metallic shimmering magnetite ore. Olivine, apatite and titanite can also be found as lesser constituents. The possibly rough surface is created by short-term heating of the stone surface and transformation of the upper crystal layer into slate-like structure.
Petrogenesis
Nero Assoluto was generated from a dark, alkaline magma type with gabbro content, which got stuck in the earth crust as a gigantic cone-shaped pluton and then cooled uniformly. Consequently, crystallisation resulted in a highly regular grain size.
