Introduction
The materials of daily-use ceramic tableware directly impact its safety, durability, and aesthetics. Whether for household or commercial use, choosing the right ceramic materials (e.g., bone china, reinforced porcelain, stoneware) and glazing techniques (underglaze vs. overglaze) is critical. This article provides a comprehensive guide to selecting tableware that meets food safety standards while balancing practicality and style.
Core Concepts: Key Materials in Ceramic Tableware
Daily-use ceramic tableware is primarily made from natural minerals like kaolin, quartz, and feldspar. Different formulations and firing processes create the following common materials:
Bone China
Contains over 30% animal bone ash, offering translucency and high hardness. Ideal for luxury tableware.
Advantages
- Translucent appearance
- Scratch-resistant glaze
- Acid/alkali-resistant
Disadvantages
- Expensive (CNY 300+ per piece)
- Relatively fragile
Reinforced Porcelain
Enhanced with zirconium silicate for significantly improved impact resistance, a cost-effective choice.
Advantages
- High durability
- Dishwasher-safe
- Budget-friendly
Disadvantages
- Less translucent
- Lower aesthetic appeal
Stoneware
Fired at high temperatures with less than 1% water absorption, suitable for oven and microwave use.
Advantages
- Heat-resistant (up to 300℃)
- Rustic style
- Microwave-safe
Disadvantages
- Heavyweight
- Not child-friendly
Glazing Techniques Comparison
Underglaze
Patterns beneath the glaze, low lead/cadmium risk, safest option.
- More durable decoration
- Higher production cost
- Preferred for food-contact surfaces
Overglaze
Patterns on the glaze surface, prone to wear and heavy metal release.
- More vibrant colors
- Lower production cost
- Not recommended for acidic foods
Material Comparison
| Feature | Bone China (CNY) | Reinforced Porcelain (CNY) | Stoneware (CNY) |
|---|---|---|---|
| Heat Resistance | Excellent (microwave-safe) | Good | Excellent (oven-safe) |
| Impact Resistance | Low | High | Medium |
| Safety | Lead/Cadmium-free | GB-compliant | Natural minerals |
| Price (per piece) | 300+ | 50-200 | 30-100 |
Buying Guide
- Identify Needs:
- Daily use: Prioritize reinforced porcelain or underglaze tableware.
- Special functions: Choose stoneware with "heat-resistant" labels for microwaves.
- Inspect Craftsmanship:
- Check for smooth, bubble-free glaze to avoid cracks.
- Overglaze patterns feel raised, while underglaze is smooth to the touch.
- Verify Certifications:
- Domestic products: Verify GB 4806.4 (China's food contact material standard).
- Exported products: Look for FDA or LFGB certification.
Safety Tips
- New Tableware Preparation:
- Before first use, boil in water and vinegar (1:1 ratio) for 10 minutes.
- Usage Warnings:
- Avoid sudden temperature changes (e.g., hot dish into cold water).
- Overglaze tableware should not hold acidic foods (vinegar, citrus).
- Cleaning Recommendations:
- Use soft sponges for bone china to prevent glaze scratches.
- Avoid abrasive cleaners for decorated pieces.
Reading Product Labels
- Material Claims:
- High-quality bone china states "30%+ bone ash content".
- Safety Symbols:
- Microwave-safe: Labeled "Microwave Safe" or with wavy lines.
- Lead/Cadmium limits: "Pb<0.5mg/L, Cd<0.25mg/L" on compliant products.
- Manufacturer Information:
- Legitimate brands disclose factory details and standards (e.g., GB/T 3532).
Professional Advice
When purchasing ceramic tableware, we recommend:
- Choosing reputable brands and authorized dealers
- Requesting material safety test reports when possible
- Considering your actual usage needs rather than just appearance
