Ardesia Nera Indiana: Complete Guide
Ardesia Nera Indiana is a dark slate that, as the commercial name indicates, is associated with the Indian market. It is chosen for flooring and cladding with a rustic and contemporary character.
History and origin
India is a major exporter of slates and split stones, but the specific origin of the batch is not documented in the company catalogue. Like all slates it is a metamorphic rock that splits into plates along parallel planes. Carrara marbles are supplied on request.
Look and veining
The colour is black or very dark grey, with possible lighter shades or veining due to minerals. The natural split surface is irregular and textured; brushed or polished it becomes more uniform. Among the pieces variations in tone and texture are noticeable.
