(July 2013) Take a slab of black or gray basalt, apply granulated glass in desired pattern and burn the slab in a kiln. Presto: the pattern is enameled unto the stone slab.
That is one of the secrets behind Nero Sicilia.
The product slogan „Born and reborn from fire“ describes more about Nero Sicilia: When this naturally gray basalt is exposed to ultra-high temperatures comparable to the volcanic source from which it came, the stone changes its color to jet black.
The innovative material with a variety of patterns was unveiled at Nuremberg’s Stone+tec, which took place at the end of May this year.
It may sound simple but in fact, the procedure is highly complicated. E.g. the temperature in the kiln must be set to modify the structure of the stone on the surface only. This is achieved with the help of added material which later has the positive side-effect of sealing the surface of Nero Sicilia.
The procedure was developed by Frama Mosaici’s Biagio Amarù and his team.
Nero Sicilia slabs are up to 3 m long, 80 cm wide and 2 – 3 cm. With applied glass patterns the slabs can be up to 2.40 m long at most.
Patterns were designed by Giovanni Salerne and Massimo Barbini. But Biagio Amarù is quick to emphasize that pattern can be adapted to client’s wishes.
