Savoia ceramic tiles are manufactured with porcelainized grès technology making them highly technological ceramic products.
They are in fact highly resistant to bending stress EN100, besides 45 N/mm. Their compactedness ensures water absorption is less than 0.5% - EN99 and EN202 frost-resistance.
This is all due to the use of fine national and international clay and quartz as essential production components, together with feldspars and white kaolin. All these components are grinded with water in rotary mills until they reach extra fine consistence. The resulting mix is then placed within a high-pressure machine (atomizer) where it gets dried through a vortex of hot air at over 600°C, creating little spheres of mixture of various sizes.
The different sizing of the spheres is necessary to reach maximum compactedness during the pressing stage. Pressing is made with highly powerful (over 2400 ton) hydraulic presses, with a pressure force of over 500 kg/cm).
Pressing is made at 6% of humidity circa, later eliminated before glazing by means of a hot-air drier reaching up to 250°C. Once dried, tiles are ready for glazing.
Glazing is made through a number of different applications: glazing huts, airbrushes for flashing, brushing machines for antique effects, shotblusting machines to add glass to the glazing, roller decorators with five or more decoration heads: each stretching over 1.5 linear meters, indented or not indented, for the production of tiles hardly ever showing the same decoration twice.
Baking is the following stage and it takes place in multi-leveled roller ovens reaching over 1250°C. Thanks to such high temperatures and to their long stay within the baking area the row materials used are completely greyed and smelted.
Baked tiles comply with current regulation on acid attack resistance, ensuring resistance to acids and bases, as well as to stains, as specified in E122 standards. Glazed tiles are highly resistant to MOHS7-9 scratching, as well as to PEI IV and V abrasion according to EN101 standards.
Selection and packaging are carried out through the most modern equipment. Tiles are selected through completely automated telecameras distinguishing tones and faults. Further equipment is used to distinguish tiles by gauge (length and weigh), squareness, flatness and thickness.
All parameters set by Savoia Italia comply with EN98 standards. Finally, tiles are sampled in boxes, divided by article/gauge/tone and selection category (1st, 2nd and 3rd choice) and placed on Europallets thermally protected against atmospheric agents even for outdoor storage.
