Non-porcelain Tiles
Based on the current normative ISO 10545-3 that rules the ceramic tile classification on their porosity the Non Porcelain Tiles can be divided in 3 main clusters as:
- BIIa water absorption (w.a%) 3 to 6%
- BIIb water absorption (w.a%) 6 to 10%
- BIII water absorption (w.a%) >10%
Unfortunately within the market place we could find other “market” classification as: monoporosa and/or wall tiles.
The quality and the consistency of the raw materials used for Non Porcelain tiles production influence the main properties of the ceramic body as:
- Strength (clay)
- Fired shrinkage (clay, kaolin)
- Fired colour (clay, kaolin, sand)
- Porosity ( clays, feldspars)
