What is the difference between high-temperature and low-temperature porcelain?

Please verify the following points and require itemized written supplier responses:（ceramic tableware high temperature porcelain） High-temperature porcelain is generally more vitrified, denser and lower in water absorption; lower-temperature products may look bright but require stricter durability and decoration checks. Consider chip resistance, water absorption, glaze hardness, rim strength, dishwasher suitability and batch consistency. Define capacity, accuracy, materials and operating environment before requesting quotes on a uniform basis. Request specification sheets, test reports, certificates, maintenance manuals and spare-part lists.

Do not compare unit price alone; include customization, freight, spare parts, after-sales support and downtime risk. Keep written records of inquiries, confirmations, FAT, acceptance and warranty commitments.
