Uses of pumice

Pumice has been widely used in Aeolian architecture because of its very low weight and its very high insulating power.
In the form of small stones it was used in traditional Aeolian architecture to cover the cannizze of attics, which in turn were supported by strong chestnut beams.
A layer of lime on top made the roof perfectly insulated.
More recently, pumice powder has been used as an inert material to be mixed with sand and cement for the construction of attics.
From an industrial point of view, pumice is commonly used to bleach and treat fabrics or in exfoliating creams and powders.
