Clay
Product Benefits
Combined with talc, feldspar, quartz/silica and kaolin, ball clays are utilized for their plasticity and bonding properties.
Ukrainian ball clays
- Higher bonding strength at both green and dried stage which can increase the module of rupture of the porcelain tile body, with the aim of reducing losses during tile production
- White-firing colour which improves the colour of fired tiles, reduces the usage of engobe in porcelain glazed tiles, improves colour development in coloured unglazed porcelain tiles, and reduces the usage of whitening agent in superwhite bodies.
- Low firing shrinkage which can increase tile size and support the flatness of larger sized tiles.
- Low level of organic matter that allows a fast firing cycle.
- High fusibility features that can reduce the final porosity of the ceramic body and increase the speed of the firing cycle, saving on natural gases and increasing production yield.
German clays
- A wide range of products which can be tailor made based on customer requests, from coloured clays up to white firing clays, with a different level of plasticity.
- Low level of organic matter that allows a fast firing cycle.
- Stable product along supplies which support the stability of the production process.
UK clays
- White firing colour which improves the colour of fired tiles and reduces the usage of engobe in porcelain glazed tiles.
- Constant product
Russian clay
- High alumina clay with good plasticity thanks to clay minerals like smectite that can be used in combination with other ball clays in order to reach the required body strength.
- White firing colour which improve the colour of fired tiles and reduces the use of engobe in porcelain glazed tiles.
- Constant product
