Plastically pressed wall and floor tiles
Clays firing to friendly colours ranging from cream-white to yellow and red. Chamottes with low rate of water absorption and adapted grain size guarantee stable shape of structural ceramics during drying and firing. Feldspathic sand (pegmatite) as white-firing non-plastic material with good shorting and vitrification properties. Mixed feldspar intensifies vitrification.
