TECHNICAL INFORMATION
 
Ceppo di Gré is a monogenic dolomitic breccia, with a conglomerate appearance, belonging to sedimentary rocks clastic, with calcareous matrix cementation.
 
It is quarried in the quarry owned by Marini Marmi company, in the municipality of Solto Collina (BG), on the North-West bank of Iseo Lake.
 
The main surface finishes are: rough sawn, honed, sand-blasted, bush hammered, chiselled, waterjet.

The dimensions of slabs are 270/290 x 130/160 cm approx, with minimum sawn thickness of 2 cm.
 
Production potential of the quarry: the current Quarry Plan of the Province of Bergamo authorises the annual production of 3500 m³ of blocks useful merchantable material. Our reservoir will enable still permit the extraction of hundreds of thousands of m³ in coming decades. 
 
Thanks to its good technical properties of frost resistance and limited reaction to atmospheric agents, Ceppo di Grè is used in construction, design, urban decoration,  parks and gardens.It's CE/EC certified for applications in which it is intended, a further guarantee of quality.
 
HISTORY
 
 
The stone called Ceppo has been used for at least two thousand years in the buildings of Milan. Rodolico  wrote that this stone was the stone the most used in the Roman times, together with others extracted from the hills of the high plains of Lombardy. At the same time it can be seen that Ceppo was used in the walls and columns of St. Ambrogio, St. Simpliciano, Arena and in St. Eustorgio, but very probably the material had been taken from other buildings and used again in the new constructions, as happened as everywhere.

Anyway the author quoted above claims that even then some quarries of Ceppo  had been opened along the banks of the rivers near Milan, where the material extracted was transported on rafts; but it was only in the 14th – 15th century that  was found evidence of quarries and transport of the blocks of Ceppo. Not only the difficulty to extract the stone and transport it to Milan by water or over land, but also the trend of the architecture was important to determine the major or minor use of the Ceppo. 

So we witnessed  periods of great use followed by others in which the Ceppo and stone materials were put to one side to follow the trend of the moment.
 
riquadratura blocchiDuring the Spanish occupation the Ceppo became once again the favourite material. Its rebirth was helped by the possibility to transport the stones load on the barges, from the quarry to the centre of the city, using the Martesana Canal, it was also determined by the choose and promotion by the architects. In the following centuries the Ceppo was less used or at least in a less evident way. In Milan Ceppo was constantly used in the monuments of the cemetery and its use was increased in the 1900s in the stone facings of numerous buildings. It was in  the beginning of this century that the quarries near the Lake Iseo were opened, from here the Ceppo was used in the nearby provinces.

During the period between the two great wars, Ceppo had its period of greatest use, especially in Bergamo and Milan, where it satisfied the requires of the architects in the Piacentini style.
In the period after the war, during the years of reconstruction, the Ceppo was used mainly for outdoor facade. Milan and the nearby cities were the major consumers. At the end of the 50s the exportation of Ceppo di Gré was well underway in North Europe, in the same period the extraction of Ceppo was reduced due the end of the quarries of Ceppo dell'Adda, di Brembate (Gentile), di Camerata and other little quarries of the same stone.
