Mallet SA

Volvic lava is considered extremely rare because the lava flows are located within the NATIONAL PARK of the AUVERGNE VOLCANOS with the extraction sites upon the flow being very small.

The lava in the Nugere crater is unique across the world & being of such quality & size that it permits enamelling & firing. All aspects of extraction are carefully monitored by Pyrolave as well as the French administrative departments. Environmental limitations are stringently followed; ‐ each extraction area is subjected to an << administrative authorization for extraction within a classified zone>> following a 2 year study of the zone. Respecting the rules of extraction is rigorously enforced. Environmental controls & inspections are frequent. Studies that record the impact upon the environment are carried out & restoration of the sites after extraction is compulsory.

The authorisation file includes the analysis & control of direct & indirect, temporary & permanent effects upon the environment & specifically a landscape study, a study on noise, dust & vibrations, hydro‐geologic & hydrologic studies. The "developer" must prove that there is no risk of pollution due to hydrocarbon, organic or mineral waste. These documents are not considered confidential & can be viewed upon request. The annual extraction for a company like Pyrolave is the equivalent to an area of 50 mtrs x 10 mtrs high. We can guarantee a yearly yield of 10‐20,000 m2 continually over a 20 year period in strict respect of the environmental rules. The lava "quarries" are situated over the flow zone of Volvic mineral waters owned by Danone (1st European food industry group) who are equally stringent about the environmental risks.

Historic Perspective

The Volvic lava has been an important historic architectural stone in France for many hundreds of years. In the large cities close to Volvic (Riom, Clermont Ferrand, Lyon) you can witness many cathedrals, municipality buildings, schools, shops & public places constructed of natural lava building blocks, carvings & statutary through to simple walling.

The Michelin company based locally to the quarry were the first to identify & use Volvic lava for glazing having secured the contract to map France. These orientation maps can still be seen on the roadside after 150 years. The original art nouveau world famous "Metro" signs were also made of glazed lava as was the facade of the equally famous Samaritaine building in Paris which is still in place today. The ancient lava quarries were a way of life & vital to the local economies. The stone being extremely heavy was very difficult to move long distances but such was the importance of the stone that Volvic railway station was built by the quarry owner to link into the national network & expand the market across France.

The natural Volvic lava continues to be used as flooring & paving stone, a material for construction (building blocks, lintels etc.) for carvings, staircases & fireplaces, industrial acid burning chimneys & as an open jointed rain‐screen facade cladding.
