Ornamental Stones

Granite is a rock composed of a combination of minerals.

Characteristics:

• Igneous rock (formed by the cooling of molten magma).
• High degree of hardness.
• Crystalline.
• Varied coloration.

Interesting Fact: Granite is harder and more resistant than marble due to its composition, which primarily consists of three minerals (mica, feldspar, and quartz), whereas marble is formed from a single mineral, calcite. Additionally, granite has fewer veins and is less porous than marble.

Quartzite is a type of natural stone abundantly found in Brazil. Formed from highly resistant sedimentary rocks, quartzite consists of 75% quartz and 25% other materials such as tourmaline, Muscovite, biotite, among others. This natural formation gives quartzite a marble-like appearance with distinct veins across its surface.

Characteristics:

• Strength and durability.
• Impermeability.
• Variety.
• Easy to clean.
• Due to its high resistance, durability, and beauty, quartzite is a stone that can be applied in various areas of the house, ranging from countertops to flooring and wall cladding.

Interesting Fact: Quartzite differentiates itself by its composition. While quartz is composed of 90% pure quartz, quartzite contains a lower percentage of quartz in its composition. This results in a distinct appearance, as quartz has a speckled surface. Another significant difference between the two stones is that quartzite can be used both indoors and outdoors, while quartz is limited to indoor use only. Furthermore, when compared to marble and granite, the differences become even more evident. Aesthetically, granite differs greatly from quartzite due to its more granulated and irregular surface.

Marble is a metamorphic rock formed from limestone that has been exposed to high temperatures and pressure.

Characteristics:

• Widely used in the construction industry.
• Varied coloration.

Interesting Fact: Commercially, all carbonate rocks capable of being polished are classified as marbles. The mineral composition depends on the chemical composition of the sediment and the degree of metamorphism, resulting in a wide variety of colors and textures.

Basalt is a fine-grained rock, typically dark gray in color, and belongs to the group of igneous rocks.

Characteristics:

• Resilient.
• Highly aesthetically pleasing.
• Limited color variation.

Interesting Fact: Basalt is an eruptive igneous rock with a mafic composition, meaning it is rich in magnesium and iron silicates and has a low silica content. It is one of the most abundant rocks in the Earth's crust.

Silestone is a composite material consisting of 94% natural quartz, making it extraordinarily hard and resistant. It is an excellent surface for kitchen countertops, bathrooms, floors, and wall coverings, with minimal joints.

Characteristics:

• Stain resistance.
• High resistance to acids.
• Scratch resistance.
• Impact resistance.
• Bacteriostatic protection.

Interesting Fact: Silestone is a non-porous surface that is highly resistant to stains. It is also one of the hardest minerals, making it highly durable.

Quartz is an industrial product composed primarily of 93% quartz and 7% high-performance binding agents (polyester resin).

Characteristics:

• High impact and scratch resistance.
• High resistance to acids and alkalis.
• Zero water absorption.
• High durability in high-traffic areas.
• Suitable for kitchen countertops and high-traffic flooring.

Interesting Fact: In addition to quartz and polyester resin, quartz surfaces are produced with other properties such as quartz sand, mirrors, and glass fragments, giving the surface a shimmering and dynamic effect.

Granite tombstones are granite plates used to mark graves and memorialize deceased loved ones. Granite is widely used in the production of tombstones due to its advantageous characteristics as an ornamental rock. Here are the benefits of using granite as a material for tombstones:

1. Durability: Granite is an extremely resistant and durable rock. It can withstand adverse weather conditions such as rain, intense sunlight, and temperature changes over time without losing its structural integrity.
2. Low maintenance: Granite tombstones require minimal maintenance. Their smooth and dense surface makes it difficult for dirt, stains, or liquids to be absorbed, facilitating cleaning and preserving the original appearance for a long time.
3. Variety of colors and patterns: Granite is available in a wide range of natural colors and patterns. This allows for customization of the tombstone according to aesthetic preferences and the desired memorial style.
4. Wear resistance: Granite is highly resistant to wear and erosion, ensuring that inscriptions and engraved details on the tombstone remain legible and sharp for many years.
5. Symbolic meaning: In addition to its physical qualities, granite is valued as a rock that symbolizes strength, longevity, and dignity. These characteristics add meaning and reverence to the tombstone, honoring the memory of the departed loved one.
6. Aesthetic value: Granite is naturally beautiful and elegant, adding a touch of sophistication to the cemetery environment. Its visually pleasing presence can bring comfort and tranquility to family members and visitors of the grave.

When choosing a granite tombstone, one can combine the physical characteristics of the rock with personal feelings and aesthetic preferences, creating a lasting and meaningful memorial to honor those who have passed away.

Sculptures made from ornamental rocks using CNC (Computer Numerical Control) machines represent a modern and precise way of creating stone artworks. This technology employs an automated and computer-controlled process to sculpt the rock based on a digital design.

CNC machines utilize various tools such as drills, mills, and diamond tips, precisely controlled to cut and sculpt the rock. The process begins with creating a digital 3D model of the desired sculpture, which is loaded into the CNC machine's software. The machine then translates this information into coordinated and precise movements to sculpt the rock according to the design.

There are several advantages to using CNC machines for ornamental rock sculptures:

• Precision: CNC technology enables a high level of precision in executing the sculptures. The measurements and details of the project are faithfully reproduced in the rock, resulting in high-quality sculptures with refined finishes.
• Repeatability: Once the digital design is loaded into the CNC machine's software, the same sculpture can be reproduced multiple times with accuracy and consistency. This is particularly useful for serial projects or when identical replicas are required.
• Complexity: CNC machines can execute intricate cuts and complex sculptures that would be challenging or impossible to achieve manually. This allows for the creation of intricate details, textures, and unique shapes that enhance the artistic value of the sculptures.
• Efficiency: The use of CNC machines speeds up the sculpting process compared to manual methods. Automation enables faster and more efficient production, reducing the time required to create a sculpture.
• Error Reduction: CNC machines eliminate human error, resulting in more precise and consistent sculptures. This reduces rework and costs associated with manual errors and adjustments.

Sculptures made from ornamental rocks using CNC machines are appreciated both in the artistic realm and in architectural applications, such as building facades, monuments, and interior decoration. This technology offers a unique combination of precision, complexity, and efficiency, allowing for the creation of truly impressive stone sculptures.
