高品質の陶磁器食器の見分け方

In the catering, hotel, and retail industries, 陶器食器 serves not only as a vessel for food but also plays a crucial role in shaping brand image. High-quality tableware enhances the dining experience while simultaneously reducing replacement frequency and saving long-term costs. However, when purchase volumes reach hundreds or even thousands of sets, the ability to quickly and accurately assess the quality of ceramic tableware becomes paramount.
This article aims to provide you with a practical guide for evaluating ceramic quality from several key aspects, including firing temperature, glaze quality, water absorption rate, and thickness design. Even when handling large orders, this guide will help you select tableware that meets your expectations.

Firing Temperature: The Core Factor Affecting Hardness and Safety

Why is it important?

The firing temperature directly determines the hardness, density and service life of ceramics. High-temperature firing (usually between 1250 °C and 1350 °C) can fully vitrify the porcelain clay, resulting in a harder and denser surface that is less prone to cracking.

Risks of low-temperature firing:

• The porcelain body has insufficient strength and is prone to cracking due to bumps and knocks
• It has a high water absorption rate and is prone to bacterial growth and unpleasant odors
• The glaze has poor adhesion and may peel off after a period of use

Procurement suggestion

When making large-scale purchases, it is recommended to confirm the firing temperature with the supplier and request relevant test reports or process descriptions.

Glaze Quality: Aesthetics and Safety

• Vision and Touch
  High-quality glaze should be smooth and fine, free of pinholes, bubbles, glaze flow or color differences. Whether it is a glossy or matte finish, it should be uniform and consistent.
• Food safety
  The glaze of ceramic tableware must comply with food contact safety standards (such as the EU LFGB and the US FDA), ensuring that it does not contain harmful metals such as lead and cadmium.
• Wear resistance and stain resistance
  High-quality glaze is easy to clean, not easily scratched by knives and forks, and not prone to attracting color spots.
• Inspection skills
  Carefully observe the glaze surface under natural light or backlight to see if there are any cracks, impurities or unevenness.

Water Absorption Rate: An Invisible Indicator of Durability

• What is the water absorption rate?
  Water absorption rate refers to the proportion of water absorbed by ceramics. The lower the water absorption rate, the denser the porcelain body is, and it is less likely to absorb water or develop an unpleasant odor.
• Industry standard
  The water absorption rate of high-end porcelain is usually ≤0.5%, which is also a common requirement for high-quality ceramic tableware internationally.
• Simple detection method
  Drop a drop of water at the bottom of the tableware and observe the penetration time. If it is absorbed in a short time, it indicates that the density of the porcelain body is insufficient.

Thickness and Weight: A Balance Between Hand Feel and Durability

Thick vs. Thin

• Thick: More durable, with strong impact resistance, but heavier
• Light and thin: It feels light and is suitable for exquisite dining occasions, but it is fragile

Selection suggestions

• Thick and solid types are suitable for high-frequency usage scenarios such as hotels and restaurants
• For household or gift tableware, it is advisable to choose a light and thin style to enhance the hand feel and aesthetic appeal
• Before making large-scale purchases, it is necessary to confirm through samples whether the thickness is in line with the brand positioning and usage scenarios.

Quality Control Suggestions for Bulk Purchases

• Request samples and sign them for production: Ensure that subsequent batch sizes are consistent with the samples
• Confirm batch consistency: The color, thickness and glaze surface should all be uniform
• Prefer manufacturers with international certifications, such as ISO, BSCI, LFGB, etc
• Introduce third-party inspection when necessary: Reduce quality risks

結論

The standard for 高品質セラミック食器 lies not only in its beautiful appearance but also in the craftsmanship and details behind it. Firing temperature, glaze treatment, water absorption rate control, and thickness design these factors that jointly determine the lifespan and user experience of tableware. Especially in large orders, the purchaser needs to ensure that each piece of tableware meets expectations through scientific methods and standardized procedures.
