Jiadoli Granite (加多利 / Jiāduōlì) is a vibrant, coarse-grained natural granite quarried in China. It features a dense combination of light grey, pale green, and dark black minerals, accented by prominent reddish-brown to rust-coloured crystal patches. Its highly polished surface produces a strong mirror-like reflection, emphasizing the stone's granular structure and dramatic mineral variation.
Texture & Pattern
- Base Colour: Light grey, pale green and dark black
- Accent Colours: Reddish-brown, rust and occasional earthy tones
- Grain: Coarse-grained
- Texture: Dense, crystalline and granular
- Pattern: Irregular, multi-directional mineral distribution with contrasting crystal clusters
- Finish: Highly polished / mirror finish
- Appearance: Dynamic and strongly variegated, with rust-coloured crystals creating distinctive focal areas
Physical & Mechanical Properties
Actual values can vary according to quarry and block. The following should be treated as indicative values until confirmed by a laboratory report for the specific material.
- Water Absorption: 0.10–0.50% by weight
- Bulk Density: 2,600–2,750 kg/m³
- Apparent Porosity: 0.3–1.5%
- Compressive Strength, Dry: 150–220 MPa
- Compressive Strength, Wet: 130–200 MPa
- Flexural Strength, Dry: 12–20 MPa
- Flexural Strength, Wet: 10–18 MPa
- Abrasion Resistance: Low wear / high resistance
- Freeze-Thaw Resistance: Generally suitable for exterior use, subject to testing
- Mohs Hardness: Approximately 6–7
Mineral Composition
Jiadoli Granite is expected to contain the typical minerals associated with coarse-grained granitic rocks. An indicative composition is:Approximate Content (% by weight)
- Quartz: 20–35%
- Feldspar: 45–65%
- Biotite / Mica: 3–10%
- Amphibole: 0–8%
- Pyroxene / Other dark minerals: 0–5%
- Accessory iron-bearing minerals: <3%
The reddish-brown crystals may be associated with iron-bearing minerals or altered feldspar, while the dark grains are commonly related to biotite, amphibole or other mafic minerals.
Chemical Composition
Indicative chemical composition for a granitic stone: Approximate Content (% by weight)
- SiO₂: 65–75%
- Al₂O₃: 12–17%
- K₂O: 3–6%
- Na₂O: 2–5%
- CaO: 1–4%
- Fe₂O₃: 0.5–3%
- MgO: 0.1–2%
- TiO₂: 0.1–1%
- MnO: <0.2%
- P₂O₅: <0.5%
These figures are indicative chemical ranges and should not be treated as certified test results without a laboratory analysis of the specific Jiadoli Granite quarry.
Applications
Jiadoli Granite's high hardness, low water absorption and strong visual character make it suitable for:
Kitchen countertops, Kitchen islands, Vanity tops, Flooring, Interior wall cladding, Exterior wall cladding, Staircases and steps, Window sills, Fireplace surrounds, Reception desks, Hotel and commercial interiors, Monumental and memorial work, Outdoor paving, Landscaping features, Tables and furniture, Architectural feature elements
The polished finish is particularly effective for countertops, wall panels, furniture and decorative architectural applications because it enhances the contrast between the light, dark and rust-coloured crystals.
Maintenance
Jiadoli Granite is relatively easy to maintain because of its hardness and low porosity.
- Clean regularly with a pH-neutral stone cleaner.
- Wipe spills promptly to prevent staining.
- Avoid strong acids and highly aggressive chemicals.
- Avoid abrasive cleaning products that may reduce the polish over time.
- Use cutting boards and trivets on kitchen countertops.
- Apply a suitable penetrating sealer when recommended for the particular application.
- Periodically check countertops and other high-use surfaces for water or oil absorption.
- Polished surfaces can be professionally re-polished if they become dull or scratched.
