The Official Naming Of The Product Is Sharpening Stone but it is known also as <<water stone>> or <<whetstone>>.
It is a natural , non metallic mining constituted at 96-99% from Dioxide of Silicon (SiO2) that it is found in micro-crystal form in the Mountains Of Elouda. It is only met there with the form of layers of sediment material that is to say constituted from skeletons (basically marine) micro-organisms. From these parallel layers of the water stone that is usually from completely white up to open grey colour excavates and then produced the known abrasive material, the whetstone.
This layers have thickness from 2 until 15 centimeters and are found between a lot of thick calcareous mining layers.
The Sharpening Stone is a infrequent mining characteristic of the region. It was excavated in the 18th century when it was also discovered by French tradesmen that they organised locally the excavation and they imported systematically already the crude product in Southern France where they created also factories of treatment and commercial houses of distribution of the final product.
The historical reports give to this fanous Stone the henceforth name of “The Stone of East”. In the mountains behind the current Schism Of Eloyntas we can easily see the traces of multiple pits of excavation of the Whetstone.
