Mahallat
Research on samples from the Mahallat area examines deterioration caused by salt crystallization, among other subjects. This matters when assessing stone for exposed environments. [1]
Travertines of Iran
Colour catches the eye. Structure, cutting direction and origin help you choose. A first guide to the regions and characteristics worth understanding before selecting a block.
Regions, not quality grades
This first overview covers selected areas documented in research. A geographical name is a starting point; comparing supplies requires identified samples and batch information.
Qorveh–Takab
Research describes thermal-spring deposits with compact, laminated and iron-rich structures. One area can contain different textures; compare the specific material. [2]
Abarkooh and Tabas
Stones from these origins were studied alongside a Mahallat travertine to assess protective treatments and artificial ageing. They provide two further distinct origins for material research. [3]
The photographs on this page show Silver Travertine already featured on the site. Its extraction area is not documented here and is not assigned to any of the regions above.
Look closely at the material
Two views of the same Silver presentation: notice the rhythm of the layers and distribution of voids. Presentation images do not replace a physical sample.
Pattern and cutting direction
Ask for images of both cutting directions: linear veining and a cloudier appearance may belong to the same material. Agree the desired pattern using a sample.
Voids and filling
Examine how voids are distributed, not just how many are visible. When comparing finishes, specify open-pore or filled stone, including the filling product.
Tone and selection
Compare photographs under similar light, with dry surfaces and several pieces from the batch. A single image cannot represent the full colour variation.
Physical data: a first documented example
Sample S7 “Kerem Hajiabad”, Bameri et al., 2025, Table 2. Density, porosity and absorption: ISRM method; compression: ASTM C170, as reported by the study. [4]
- Dry density
- 2.46 g/cm³
- Effective porosity
- 5.55 %
- Water absorption
- 2.25 %
- Compressive strength
- 50.85 MPa
Values for the studied sample, not regional averages or certification of blocks for sale. No batch-specific test report is available here for the illustrated Silver.
Flexural strength, freeze–thaw, abrasion and slip resistance: batch data unavailable. Required tests depend on the intended application.
Sourcing: what to check
A deposit does not guarantee immediate supply. For each selection, we collect practical information:
- Actual blocks and date of the availability check.
- Usable dimensions, integrity and cutting direction.
- Quantity obtainable with consistent colour and pattern.
- Preparation, processing and shipping times to be confirmed.
We do not yet publish typical quantities or lead times for these regions: current commercial checks are missing. Individual records show the status of materials already in the catalogue.
Travertines on the site
Records link to the catalogue. “On request” means availability must be confirmed; it does not mean ready for delivery. Colour is never used to infer extraction origin.
