The range
Marble & Onyx Slab
The lines an importer needs alongside travertine to close a project: Cappuccino Forest, Bianco Lasa, Fantastic Onyx, Pietra Grey, Spanish Dark and Bronzetto, polished or honed. These come from partner quarries, not ours, and we say so — a supplier who claims to quarry fourteen materials in one district is describing a warehouse, not a quarry.

Technical data
Our reading on the left, the standard on the right.
Values are from the current production run on Ivory and Classic, tested to the European methods named in the last column. Where a harmonised standard sets a limit we quote it; where the limit is our own we say so, because in this trade an in-house rule and a CE requirement get blurred deliberately and often.
| Parameter | Unit | Petrarra | Limit / standard |
|---|---|---|---|
| Apparent density | g/cm³ | 2.45 | EN 1936 — declared value, no minimum |
| Open porosity | % | 2.9 | EN 1936 — declared value |
| Water absorption, atmospheric | % | 1.6 | EN 13755 — declared; Denizli basin runs 0.9 – 2.6 |
| Compressive strength | MPa | 62 | EN 1926 — declared; basin range 44 – 70 |
| Flexural strength, concentrated load | MPa | 11.4 | EN 12372 — declared value |
| Abrasion resistance, wide wheel | mm | 21 | EN 14157 — lower is better; declared |
| Frost resistance | cycles | 48 | EN 12371 — flexural loss under 20 % required |
| Slip resistance, unpolished, dry | USRV | 41 honed / 57 tumbled | EN 14231 — declared per finish |
| Thickness tolerance, calibrated tile | mm | ± 1.0 | EN 12057 class 1 permits ± 1.5 |
| Length and width tolerance | mm | ± 0.8 | EN 12057 class 1 permits ± 1.0 |
| Flatness deviation, 40.6 cm tile | mm | 0.4 | in-house reject above 0.6 |
| Reaction to fire | class | A1 | EN 13501-1 — natural stone, without testing |
| Filling material | — | Resin + cement, colour matched | unfilled supplied for external use |
Denizli travertine is not one material. Values above are for Ivory and Classic from our own benches; Country Classic and Walnut are denser and read differently on porosity and absorption. Ask for the bench-specific sheet before you write a specification against these numbers.
