The Quarry
Clay with a high galestro and calcium carbonate percentage digging during summer time.

Dry Grinding
With hammer mill and vibration sift to obtain a dust
with a fine granulometry.

Blunging
The clay blunging is with addition of water (about 15 %) to make it plastic.

Extrusion
The clay, under vacuum state, is pushed to the extrusiion mouth, called drawplate.

Drying
In tunnel or statics rooms with different storage times.
In respect to each product the drying is obtained
with a combination of warm (about 100) and wind.

Brushing
The brushing and grinding of the surface is by abrasive paper. The "rustic" surface is obtained by the action
of steel brushes.

Firing
In tunnel furnace with metan with a cycle of 72 hours. Max. firing temperature about 1.000 °c.

"Wetting"
After quality control and packing the material is dipped under water for min. 3 hours to slake calcium carbonate.
