Frequently Asked Questions

PATRA manufactures two distinct commercial-grade ceramic bodies engineered for specific hospitality environments:

• Hard Commercial Porcelain: Formulated using fine kaolin, feldspar, and quartz, fired at high temperatures exceeding 1,300°C. This produces a dense, fully vitrified body with ultra-low water absorption (<0.1%). It provides the exceptional mechanical density and scratch resistance necessary for heavy-duty banquet, buffet, and all-day dining service.
• Fine Bone China: Formulated with a minimum of 43% tri-calcium phosphate (refined bone ash). Fired with precise atmospheric control, it achieves high translucency, a warm ivory tone, lightweight elegance, and remarkable flexural strength. It is the premier specification for fine dining, executive lounges, VIP catering, and wedding venues.

Yes. All standard white ware porcelain and bone china collections manufactured by PATRA are engineered to withstand commercial kitchen stress:

• Commercial Warewashing: Glaze formulations resist chemical corrosion from aggressive commercial detergent solutions and rinse aids over thousands of washing cycles.
• Thermal Resistance: White ware items withstand rapid temperature changes without cracking or crazing. They are fully safe for use in microwave ovens, warming cabinets, and standard convection pass-through heaters.
• Precious Metal Decor Care: Tableware featuring gold or platinum bands or metallic overglaze decals requires standard low-temp or gentle wash cycles to maximize the aesthetic longevity of the precious metal finish.

Our engineering team designs every rim profile, plate foot, and handle connection with operational stress distribution in mind. We apply reinforced rolled-edge profiles to high-impact hotel rim plates, reducing mechanical breakages. Additionally, raw material batches undergo daily thermal shock testing (rapid cycles from hot oven to cold ice bath) to ensure structural stability in high-tempo kitchens.

Yes. PATRA maintains a full-service technical studio and decoration plant offering comprehensive OEM and ODM solutions for global hotel chains, fine-dining groups, and brand owners:

• Brand Logo Backstamps: Custom high-fire underglaze or on-glaze logo prints on plate undersides or cups.
• Bespoke Decal & Pattern Development: In-house graphic designers create signature rim treatments, full-bleed artwork decals, metallic banding, and custom glaze colors matched to brand guidelines.
• Custom Shape Engineering: From technical 3D CAD modeling to physical plaster sampling and trial firing, we collaborate directly with culinary directors to create proprietary holloware and plate shapes.

Upon receipt of artwork or design briefs, our technical studio generates electronic proofing documents within 3 to 5 business days. Following digital approval, physical decorated pre-production samples are produced and shipped via express courier within 14 to 21 days for final visual and functional verification before mass production.

As a direct manufacturer, our standard commercial terms are structured for project supply and wholesale distribution:

• Standard Catalog White Ware: MOQ starts from 500 pieces per SKU. Standard manufacturing lead time is 30 to 45 calendar days after deposit and artwork sign-off.
• Custom OEM & Decorated Projects: MOQ typically ranges between 1,000 and 3,000 pieces per SKU depending on item complexity and decoration style. Manufacturing lead times average 45 to 60 calendar days.

All items are packed using heavy-duty, 5-ply corrugated export cartons with customized inner dividers, protective tissue layering, and bubble wrap. Cartons are loaded onto fumigated wooden or plastic export pallets, shrink-wrapped, and corner-strapped to guarantee full cargo integrity during international container shipping.

PATRA maintains long-term mold archives and precise digital glaze-formulation records for all standard and custom collections. Hotel purchasing directors can seamlessly re-order replacement inventory years after original installation, ensuring identical body whiteness, weight, dimensions, and stacking tolerances across operational years.
