Our clays are to be included in the category of filtered clays, where you will find the mixtures that undergo a washing process through filter presses. A mixture of clays expertly dosed according to the type of mixture to be obtained, is dissolved in water and subsequently sifted through a mesh with micron-sized mesh, to prevent even the smallest part of impurities from ending up in the final product. The slurry is thus pumped into the filter presses which separate the unnecessary part of water from the solid part formed by the clay which will appear in the classic "cake" shape. The last manufacturing process is the drawing of the clay cakes through degassers which will give the dough the shape of a loaf weighing 25kg. The mixtures in this category are all suitable for glazing and some have characteristics capable of being used in the dishwasher and microwave.
