Rosso Levanto

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.

It has been one of the most challenging tasks in the stone manufacturing industry to handle such relatively soft and very sensitive stones. A quite complex process assures again breakage after the blocks have been cut into thin slabs at the quarry. These procedures include a reinforcement by fusing a fiber glass netting onto the rear side of each slab as well as filling and gluing the pores and cracks with polyester resin. Stone slabs with such a preparation are the materials we are going to work with at our factory.

Petrography

Mostly scarlet to wine-red grey, seldom also dark-green to grey-green rock, which is crossed by numerous white to white-grey calcite veins. In the case of Rosso Levanto, the otherwise characteristic green colouring for serpentinite has been substituted by a wine-red pigmentation, as the iron content has largely been oxidised into hematite (iron oxide). Colour continuity in the fracture does not exist. In several places, the rock changes into green serpentinite. 

Petrogenesis

Serpentinite has been generated by metamorphosis of ultra-alkaline plutonic rock (peridotite), whereby the former material content, mainly olivine, has been fully decomposed into the mineral serpentine. By adding "ite? the rock characteristics are indicated. Therefore, serpentinite is rock, which mainly consists of the mineral serpentine. In most occasions, new generation of minerals occurred versatile and simultaneously; therefore, these are multi-coloured rocks. An additional décor element is the filling of the numerous clefts, generated by tectonic, with differing thick white calcite veins. The formerly crystalline structure of the peridotite original rock was lost in the metamorphosis process.
