Product Introduction
5-extra Cassani Abrasive is oxalic acid pressed abrasives stone, made with selected materials and exclusive oxalic acid bond, to get high mirror polishing at low polishing cost.
The core advantage of oxalic acid grinding blocks(5-extra Cassani Abrasive is one kind of oxalic acid grinding block) is that they can efficiently form a "protective film" on the surface of stone that combines hardness and luster. Make the polished stone have a longer lasting luminosity. At the same time, the price is relatively cheap. So it gained a large number of users.
Note:
5-extra Cassani Abrasive is an exclusive polishing tool for calcium carbonate (CaCO) stone, only suitable for calcium containing stones such as marble, limestone, terrazzo, etc. For silicate stones such as granite and quartz, o5-extra Cassani Abrasive cannot undergo effective reaction and is ineffective when used

Features and Advantages of Oxalic Acid Polishing Blocks
The 5-extra Cassani Abrasive is mainly made of oxalic acid as a binder, which we also refer to as oxalic acid polishing block. It has the following advantages and characteristics when used for stone grinding and polishing.
Exceptional Polishing Efficiency and High Gloss
Through a chemical reaction, these blocks rapidly enhance the surface gloss of stone, effortlessly achieving a finish of over 90 degrees-or even a high-gloss, mirror-like effect of 100 degrees. Compared to traditional abrasives, polishing time is significantly reduced, resulting in a substantial improvement in work efficiency.
Efficient Chemical Polishing Mechanism
This constitutes its fundamental advantage. Oxalic acid (H₂C₂O₄) undergoes a chemical reaction with calcium carbonate (CaCO₃)-the primary constituent of calcium-bearing stones such as marble-to form a hard, dense crystalline layer of calcium oxalate (CaC₂O₄). This thin film fills the microscopic pores on the stone's surface, thereby imparting a mirror-like luster.
Physical Abrasive-Assisted Leveling
To enhance the polishing effect, abrasives such as diamond micro-powder and aluminum oxide are frequently added to the formulation. These abrasives perform physical grinding, effectively removing minute scratches and rendering the stone surface finer and smoother.
Rapid Polishing with Long-Lasting Results
Users consistently report that these oxalic acid polishing blocks deliver "rapid glossing and excellent restoration effects." Furthermore, the resulting crystallized surface layer exhibits superior abrasion resistance; it is highly resistant to hydrolysis and retains its luster without dulling over time.
Durability and Stability Combined
The product boasts stable performance characteristics and offers a long service life. By utilizing high-quality oxalic acid raw materials in conjunction with fully automated grinding or polishing machines, it ensures consistent and uniform polishing results.
Versatile Application Scenarios
Highly versatile in nature, these blocks are compatible with a wide array of equipment, including all types of automated continuous grinding lines, single-head grinders, and stone restoration machines.
Ease of Use and High Cost-Effectiveness
Operation is relatively straightforward, and block replacement is quick and convenient.
Moreover, compared to complex chemical polishing agents, this product offers a more economical solution, making it a highly cost-effective choice.
Primarily for Natural and Engineered Stone
Widely utilized for the surface polishing and thickness calibration of various stone materials-including marble, engineered marble (agglomerate), and quartz stone-these blocks help achieve a smooth, refined surface finish that facilitates subsequent polishing processes.
Limitations of Oxalic Acid Polishing Blocks
Applicable Only to Calcium-Rich Stone Materials
The chemical reaction involved relies on calcium carbonate (CaCO₃); therefore, these blocks are suitable only for materials such as marble, limestone, and terrazzo. They are completely ineffective on silicate-based stones, such as granite and quartz.
Risk of Long-Term Acid Etching
This constitutes the most significant potential hazard. As an acidic substance, oxalic acid-when used over extended periods-erodes the softer components and binding agents within marble. This accelerates the stone's pulverization and may lead to surface defects such as "orange peel" texture, pitting, darkened grout lines, and color variations.
Potential for Diminished Luster
For certain products containing excessively high concentrations of oxalic acid, the resulting crystallized surface layer possesses limited hardness. Consequently, under conditions of frequent foot traffic and routine cleaning, the stone's surface luster is prone to rapid deterioration.
Impact on Human Health and the Environment
Oxalic acid itself is toxic and acts as an irritant to the skin and mucous membranes. However, when utilized in accordance with industry standards-typically involving dilution with copious amounts of water and the use of appropriate protective gear-the direct health risks to humans remain relatively controllable. Nevertheless, the irreversible damage that oxalic acid inflicts upon stone materials remains a persistent environmental concern within and beyond the industry.
