In hospitality-grade porcelain manufacturing, three core minerals—kaolin, feldspar, and quartz—form the foundation of performance-driven tableware. Kaolin contributes structural strength and refined translucency, while feldspar and quartz enable controlled vitrification, delivering the durability required for commercial dining environments.

When these materials are precisely balanced, porcelain achieves a level of consistency, resilience, and visual refinement that surpasses conventional ceramics. This formulation discipline is especially critical in premium hospitality collections, where brands such as PITO focus on long-term performance, aesthetic stability, and operational reliability.

Key Materials in Porcelain Formulation

Kaolin’s Structural Role

Kaolin functions as the structural backbone of porcelain, providing the plasticity required for precise shaping while maintaining dimensional stability during high-temperature firing. Its high melting point ensures plates and serving ware retain their form—an essential requirement for large-scale, consistent production.

High-purity kaolin with low iron content delivers a clean, white appearance, supporting the visual standards expected in luxury hotels and professional dining venues. Above 1000°C, kaolin transforms into mullite, reinforcing the internal microstructure and enhancing resistance to deformation and mechanical stress.

The table below outlines the key properties that make kaolin indispensable in commercial porcelain formulation:

Feldspar as Vitrifying Agent

Feldspar serves as the primary vitrifying agentin hospitality-grade porcelain bodies, introducing fluxing oxides that promote controlled melting and the formation of a stable glassy phase during firing. This vitrification process binds ceramic particles together, creating the dense, non-porous structure required for high-traffic hotel and restaurant use.

Typically beginning to melt at approximately 1150°C, feldspar performs optimally at 25–35% content in porcelain formulations. At this range, it lowers the maturing temperature while enhancing fired strength and translucency—two critical attributes for commercial tableware that must balance durability with refined appearance.

• Feldspar provides the flux required for effective vitrification in commercial porcelain bodies.
• It binds the ceramic matrix, forming a smooth, glassy surface that supports both hygiene and aesthetics.
• Proper feldspar content enhances resistance to chipping and surface wear, extending product lifespan in hospitality operations.

Quartz for Stability

Quartz plays a critical role in stabilizing porcelain bodies for commercial production, contributing both mechanical strength and thermal reliability. As a non-plastic raw material, it moderates plasticity and reduces drying shrinkage, supporting dimensional accuracy during forming and drying.

During firing, quartz helps counteract excessive shrinkage and increases melt viscosity, minimizing risks such as deformation or softening. It also forms a skeletal framework within the body, reinforcing mechanical strength and thermal stability—key requirements for porcelain subjected to frequent washing, temperature fluctuations, and daily service cycles.

The table below summarizes the functional contributions of quartz in hospitality-grade porcelain:

PITO upholds strict sourcing standards for all raw materials. You can trust that every batch of kaolin, feldspar, and quartz meets non-toxic, eco-friendly, and certified quality benchmarks. This commitment ensures your porcelain achieves the highest standards of safety, durability, and visual appeal.

Impact on Porcelain Properties

Strength and Durability

In hospitality-grade porcelain, strength and durability are determined by the precise balance of kaolin, feldspar, and quartz, each contributing a distinct function to the fired body. Kaolin establishes the structural framework, feldspar drives vitrification and density, and quartz reinforces mechanical resistance.

Adjusting these proportions directly impacts how well porcelain withstands daily service demands in hotels, restaurants, and catering operations, including repeated handling, washing, stacking, and transport.

The following table shows how different proportions affect mechanical strength and durability:

Increasing quartz content enhances mechanical strength, but excessive kaolin can reduce translucency—an important consideration for luxury hospitality tableware. Achieving this balance is critical in commercial production, where durability must align with visual refinement.

PITO’s Premium Fine Porcelain Plates exemplify this formulation discipline, delivering high impact resistance and reduced chipping rates—qualities that support long service life and lower replacement costs in hotels and restaurants.

Laboratory evaluations further indicate that selected material additions, such as spodumene tailings, can improve flexural strength and thermal stability when applied within an optimal range of 25–35 wt%.

This data-driven formulation approach ensures porcelain bodies meet the strength, reliability, and consistency standards required for professional hospitality use, rather than relying on trial-and-error adjustments.

Translucency and Whiteness

Translucency and whiteness distinguish premium porcelain from standard ceramics, particularly in upscale dining environments where presentation is integral to the guest experience. High-purity kaolin with low titanium and iron content enhances light transmission while maintaining a clean, refined white tone.

Feldspar contributes to translucency by promoting vitrification, though excessive levels may compromise structural stability if not properly balanced. Quartz, when precisely calibrated alongside kaolin and feldspar, ensures that visual refinement does not come at the expense of performance.

Here is a summary of how each material affects translucency and whiteness:

You can see the difference when you compare product types:

PITO’s Flower Decal Green Dinnerware Set and Horeca Blue Flower Porcelain Dinner Plate both showcase excellent whiteness and controlled translucency. These features create a refined dining experience and elevate the visual appeal of your table settings.

Note: Studies show that whitening agents and the balance of kaolin, quartz, and feldspar can influence the overall appearance of porcelain, especially in dental and hospitality applications.

Workability and Forming

Workability and forming behavior are decisive factors in large-scale porcelain production, particularly for commercial and hospitality tableware. A well-balanced body formulation ensures consistent shaping, smooth surfaces, and reduced defect rates throughout manufacturing.

When this balance is not maintained, defects such as craters, black specks, or reduced frost resistance may occur—leading to yield loss and inconsistent quality. Insufficient mullite formation or inadequate aluminum oxide content can result in unbound SiO₂, complicating production control and compromising the strength of the fired body.

Common forming challenges in commercial porcelain production include:

• Surface defects such as craters and black specks, which reduce strength and frost resistance.
• Low mullite content, leading to diminished physical and mechanical performance.
• Insufficient aluminum oxide levels, resulting in unbound SiO₂ during high-temperature firing.

These challenges are mitigated through the use of high-quality raw materials and precise formulation control. PITO’s White Vintage Floral Plates demonstrate how advanced forming techniques and strict quality management preserve shape accuracy and surface integrity. This consistency is especially valuable for large banquet programs and customized hospitality orders, where uniform appearance and predictable performance are essential.

Tip: Always monitor the balance of kaolin, feldspar, and quartz during production. This practice ensures that your porcelain remains easy to form, strong, and visually appealing.

Porcelain Body Ratios and Formulation

Standard Mixing Ratios

Consistent quality in commercial tableware begins with precise material proportions. Industry-established ratios for kaolin, feldspar, and quartz provide a reliable foundation for producing hospitality-grade porcelain with predictable performance:

These ratios enable precise control over density, water absorption, and fired strength. For example, a 50:25:25 blend (kaolin:feldspar:quartz) produces a dense porcelain body with low water absorption and high fired strength—ideal for hospitality environments requiring durability and hygiene.

PITO’s manufacturing process is designed to maintain these ratios consistently, ensuring each production batch meets stringent hospitality performance standards.

Effects of Ratio Variations

Adjusting the proportion of each raw material directly influences the final performance and manufacturing behavior of porcelain tableware. The table below summarizes how ratio variations affect firing behavior, densification, and long-term stability in commercial production:

Tip: In addition to material ratios, particle size distribution and compaction pressure significantly influence densification, shrinkage, and water absorption. Higher forming pressure supports greater dimensional consistency, particularly in thicker plates and serving ware commonly used in hospitality settings.

Practical Formulation Tips

Porcelain body formulation can be optimized by adhering to established industry guidelines:

• Select kaolin with low iron, magnesium, and titanium content to enhance translucency and color stability.
• Blend complementary kaolins, such as Grolleg and New Zealand, to balance workability with visual refinement.
• Maintain a Si:Al ratio close to 4:1 to achieve optimal fired performance.
• Adjust feldspar content according to firing temperature requirements.
• Target water absorption rates below 2% to ensure hygiene, durability, and suitability for hospitality use.
• Increase alumina to improve strength, while avoiding excessive reduction that may weaken the body.
