Although very elegant, its intense shine may be too formal or not suitable for contemporary styles that demand a more sober aesthetic.

 

  • Flamed Granite: This is obtained by applying a thermal lance to the surface of the granite, causing the grain to “pop.” It creates a rough texture. This finish is ideal for exteriors and areas where a non-slip surface is required, such as terraces or public areas, as required by the Technical Building Code (CTE-SUA). Unlike honed granite, which is smooth, flamed granite offers a coarser and more rustic appearance.

 

  • Satin Finish Granite: This finish is among the most demanded. It offers a smooth surface but with some texture. It provides a slight reflection without being as matte as honed granite, making it an excellent option for those looking to give some personality to the product. Satin finish is popular in facades and interior cladding where an elegant but not overly shiny finish is desired.

 

  • Granulated Granite: The granulated finish is executed through impacts of stainless steel balls under pressure, creating a rough and textured surface. Similar to the flamed finish, it is particularly suitable for outdoor applications where high slip resistance is needed, such as pavements and areas with heavy pedestrian traffic, complying with the standards required by the Technical Building Code (CTE-SUA). Its texture is much rougher than that of honed granite and slightly lightens the color of the material, making its use for indoor pavements less common.

Antibacterial properties of granite: a hygienic option for worktops

In a world where hygiene and cleanliness have taken on unprecedented importance, choosing the right material for kitchen and bathroom worktops takes on unprecedented relevance. Granite, known for its durability and natural beauty, is emerging today not only for these aesthetic and functional qualities, but also for its outstanding antibacterial properties. At Marcelino Group, our experience in countless interior design projects underlines the versatility and hygienic character of granite, demonstrating its ability to enrich every space with its elegance and functionality. Therefore, in this post we will go into more detail on how granite is the ideal material to guarantee hygienic surfaces.

What is an anti-bacterial material?

 

In the context of increasing hygiene and health standards, it is essential to understand what makes a material antibacterial. An antibacterial material is a material which, either by its natural composition or by specific treatment, is capable of inhibiting the growth or reproduction of bacteria. This capability makes it an ally in the prevention of contamination and the spread of disease, especially on surfaces that come into frequent contact with food, hands and everyday objects.

With this in mind, while there are a number of materials that offer antibacterial properties, granite stands out among them.

Propiedades antibacterianas del granito

 

Although not often talked about, granite has natural antibacterial properties. Its low porosity surface effectively prevents the build-up of bacteria and other microorganisms, making it a perfect choice for areas where cleanliness is essential.

In addition to its inherent antibacterial properties, granite’s other properties such as durability, stain, scratch and heat resistance make it an attractive choice for bathrooms and countertops. Granite’s ability to resist bacterial growth is further enhanced by its ease of cleaning. Unlike other materials that may require aggressive cleaning products to keep them hygienic, granite can be kept clean with a simple solution of water and mild soap, thus avoiding the need for chemicals that could be harmful to health.

With over six decades of experience in quarrying and processing premium quality granite from our quarries, we at Marcelino Group are committed to providing a material that is not only aesthetically superior and durable, but also promotes safer and healthier environments.

Comparison with other materials

 

When granite is compared to materials such as wood or stainless steel, granite stands out not only for its aesthetic appeal but also for its superiority in terms of hygiene. Unlike wood, which can retain bacteria in its pores and fissures, or stainless steel, which despite its name can scratch and harbour bacteria in those scratches, granite retains its integrity over time.

Granite’s ability to withstand daily wear and tear without losing its natural beauty or hygiene is unparalleled. Materials such as laminate can deteriorate or peel over time, creating crevices where bacteria can proliferate. On the other hand, granite maintains a smooth, continuous surface thatcan be effectively cleaned and disinfected.

Granite applications

Granite in the kitchen: The importance of worktop hygiene

 

Far from being simple work surfaces, kitchen worktops become the epicentre of the home, where everyday life takes shape. Keeping these surfaces hygienic is essential to prevent the transmission of bacteria and to ensure the safety of the food we share with family and loved ones.

Such a surface must face daily challenges such as contact with hot elements, oils and frequent use of cutting utensils, which demands exceptional resistance. In this area, granite stands out for its heat tolerance, its hardness and its ability to repel most stains, marking a notable difference with materials such as marble or certain woods, which tend to be more vulnerable to damage and stains.

Granite in the bathroom: Cleanliness raised to the highest expression

 

The bathroom, a personal haven for grooming and relaxation, demands surfaces that not only reflect beauty, but also support impeccable hygiene. This is where granite, with its natural antibacterial properties, distinguishes itself as the ideal choice for worktops, sinks and floors.

Its robustness against humidity and the ease with which it can be kept clean make it the perfect candidate for environments that seek to combine functionality with refined design.

Care and maintenance of granite

 

To preserve the antibacterial properties and beauty of granite, it is important to follow some maintenance practices. For daily cleaning, we recommend the use of warm water and neutral soap, a mild solution that is effective without being harmful to the granite surface.

This is particularly important in kitchens and bathrooms, where frequent cleaning is essential to maintain a healthy environment. Avoiding the use of acidic or abrasive products is key, as these can damage the sealer applied to the granite and thus its stain resistance and surface integrity, preventing bacteria and micro-organisms from finding a place to proliferate.

By following these care and maintenance recommendations, granite worktops in the kitchen and bathroom will not only retain their beauty and durability, but will also continue to provide a hygienic and safe surface for the whole family.

If you are contemplating the renovation of your kitchen or bathroom and are looking for a material that perfectly harmonises aesthetics with advanced hygienic functionalities, we invite you to explore Marcelino Group’s wide range of granites.

Meticulous focus and profound understanding of its extraction are essential to ensure an efficient and sustainable process.

Geological Characteristics and Location of Granite Quarries

 

The genesis of granite originates from the slow solidification of underground magma, facilitating the growth of crystals that are visible to the naked eye. This plutonic igneous rock is composed of quartz, feldspar, and mica, and is recognized for its durability and beauty. Granite quarries are located in geological areas rich in igneous rocks, often in mountain belts and regions with a geological history characterized by magmatic activity.

Stages of the Extraction Process in a Granite Quarry

 

The process of extraction and mining in a granite quarry consists of a series of interdependent stages that ensure efficient and safe acquisition of the material.

Geological Study and Prospecting

 

Before commencing extraction, a comprehensive analysis is carried out to determine the mining scope and production scale. This analysis involves evaluating natural, economic, and technical factors that will influence the operation. This ensures that extraction adapts to the specific conditions of the quarry and maximizes its efficiency and profitability.

Transport Development and Initial Loading

 

Transport development is crucial for establishing routes from the mine to points of natural stone transformation and the waste dump area. Methods such as road development and the use of mast crane systems without trench development are employed to optimize loading equipment efficiency. These methods allow flexibility and adaptation to changing operational needs.

Initial Extraction

 

Mining begins with the extraction of the upper layer, removing overlying soil and non-mineral rock layers covering the deposit. Excavation and splitting methods are used to separate rock from minerals, involving manual tools, drilling, wedging, and controlled cracking techniques. These processes are fundamental for exposing mineral reserves.

Granite Extraction

 

The extraction process can be carried out through two methods. First, controlled drilling and blasting of large granite stone blocks. Second, using diamond wire cutting equipment. In both cases, the aim is to obtain manageable-sized granite blocks for transport and subsequent transformation.

Block Cutting and Lifting

 

Granite blocks are cut using diamond saws into specific sizes and shapes as needed. Tools like manual jacks, hydraulic stone machines, and push air bags are used to perform this crucial task. Precision and safety are essential at this stage. Lifting these blocks from the quarry floor is done using cranes and other heavy lifting equipment.

Cleaning and Waste Transport

 

Crushed stone that doesn’t meet block standards is transported out of the block processing plant for proper disposal. Proper waste management is vital to ensure the operation’s sustainability.

Environmental and Social Considerations

 

Extraction and mining in granite quarries must address environmental and social concerns. Changes in the landscape, dust and noise emissions, and involvement of local communities are critical aspects to consider. Planning and implementing sustainable extraction practices are essential to mitigate negative impacts and promote equitable development.

Marcelino Group’s aggregate plant is a clear example of sustainability and environmental respect, as the waste and debris generated from granite are recycled and transformed into aggregates of various sizes. These are subsequently supplied to concrete plants, terrazzo factories, construction material warehouses, and more.

Furthermore, sector regulations mandate that once a quarry’s exploitation is complete, the responsible company must rehabilitate the affected areas. Many reclamation projects focus on creating lakes, parks, green spaces, as well as restoring local fauna and flora.

Conclusions

 

The process of extraction and mining in a granite quarry is a comprehensive and meticulous endeavor that spans from geological study to the formation of finished blocks. Each stage requires an analytical approach and specialized skills to ensure an efficient and sustainable operation. This analysis provides an in-depth view of the complexity involved in granite extraction and mining, essential components of the construction and ornamentation industry. Meticulous attention to each stage ensures the acquisition of high-quality blocks that satisfy both technical requirements and aesthetic demands.
