General
Characteristics
A great purity limestone and bone colour, clear shade and compact. Its
grain is fine.
About its extraction, in big blocks is done in the called Paraje de la
Aduana, in the Serranía de Loja (Granada), in extensive working
fronts of quarries, with several banks of approximate height between 10
and 12 metres.
About superficial ending, take any suggested types of this kinds of stones.
