190 million years old - and still up to date!

There are many different types of slate around the world. The slate chosen by uccellino comes from Germany and due to its composition and formation is not an oil shale, but an asphalt-gray to deep black bituminous mudstone from the early Jurassic period. About 190 million years ago in the Middle Ages, more precisely in the Lias Epsilon, the Lias Sea or also called Jurassic Sea extended over a wide area. When the water masses once flowed into the open sea, huge layers of mud were left behind. Large numbers of marine animals were caught and trapped by the silt. The dead animals were soon covered and preserved by the washed-in clays and limestones. Under high pressure and complete exclusion from the air, the mud was compressed layer by layer over millions of years to form Jurassic shale.

The deeper the shale is mined, the harder the rock becomes. It is known for its exceptional fossil preservation. Due to the low-oxygen and partly anoxic, so-called euxinian environment at the time of deposition, one can still find very well preserved crinoids, ammonites, fish and spectacular ichthyosaurs. After about 12 meters, the excavation reaches a horizontally bedded shale layer with an average thickness of 18 cm. In order to reach this layer, it is necessary to dig deep with the most modern machines.

uccellino uses only this particular layer, called fleist.
The small shell inclusions, also called posidonia, make each slate product unique.

We have produced exclusive home accessories from this slate like the shallow bowl Roxette and the candlesticks Cara.


Please do not put slate products in the dishwasher, but wash them by hand. Use only care products for natural stones for cleaning and refrain from all sharp and acidic cleaning agents.
