How to choose a Yixing teapot?

Choosing a Yixing teapot you love requires considering the clay, craftsmanship, form, functionality, and your personal needs. Here is a systematic purchasing guide:

---

### 🔍 **I. Clarify Your Purpose and Define Your Needs**
1. **Personal Use**  
   - **Capacity**: Choose according to the number of tea drinkers (for example, a small teapot under 200 ml for 1-2 people, and a medium teapot of 300-400 ml for 3-5 people).  
   - **Clay suitability**:  
     - Zini clay (highly breathable) is suitable for pu-erh and black tea.  
     - Zhuni clay (dense and aroma-retaining) is suitable for oolong and Tieguanyin.  
     - Duanni or lüni clay (which dissipates heat quickly) is suitable for green tea and white tea.  
   - **Form preference**: Round teapots retain heat well (suitable for black tea), while flat teapots dissipate heat quickly (suitable for green tea).

2. **Collecting**  
   - Consider the maker's professional title (such as a nationally certified artisan), the scarcity of the clay (such as raw ore from Huanglong Mountain), and the complexity of the craftsmanship (fully handmade > semi-handmade > slip-cast).  
   - Beginners are advised to start with works by young and mid-career artisans in the 500-1,000 yuan price range, which offers a relatively balanced potential for appreciation and risk.

3. **Gifting**  
   - Consider regional differences: Chaozhou and Shantou favor small Mengchen-style teapots; northern regions are better suited to large round teapots; Japan and South Korea favor side-handle or Shipiao teapots.  
   - Custom engraving can make the gift more meaningful.

### 🧪 **II. Identifying Authenticity of the Clay (Core)**
1. **Color and Texture**  
   - Authentic Yixing clay: Natural colors (purplish brown, dark red, or beige), a subtly grainy surface, and no shine or garishness.  
   - Chemically treated teapots: Bright, vivid colors (such as brilliant red or glossy purple), with a smooth or "plastic-like" surface.

2. **Water Absorption and Weight**  
   - Authentic Yixing clay: It absorbs water quickly after being rinsed with boiling water (due to its dual-pore structure) and dries slowly; it feels substantial in the hand (density 2.6-2.8 g/cm³).  
   - Chemically treated teapots: Water droplets slide off without being absorbed; they are relatively lightweight (density 2.2-2.4 g/cm³).

3. **Safety Tests**  
   - Pour boiling water over the teapot: authentic Yixing clay has no pungent odor (only an earthy clay smell), while chemically treated teapots may have a chemical odor.  
   - Test the inner wall with pH paper: authentic Yixing clay is neutral (pH 6.5-7.5), while chemically treated teapots may be acidic.

### 🎨 **III. Examining Craftsmanship and Form**
1. **Craftsmanship Standards**  
   - **Three points in a line**: The spout, lid knob, and handle should be aligned; an inclination of ≤3° is ideal.  
   - **Natural connections**: The joints between the spout/handle and body should be free of burrs, with smooth transitions.  
   - **Airtightness**: After filling with water, press the air hole and invert the teapot; the lid should not come off.

2. **Form and Aesthetic Appeal**  
   - Classic recommendations: Xishi teapots (rounded and graceful), Shipiao teapots (simple and dignified), and antique-style teapots (majestic and stately).  
   - Signs of fully handmade construction: clay-slab joining marks on the inner wall and uneven clay density (tighter on the outside and looser inside); mold-made teapots have uniformly smooth inner walls.

### 💧 **IV. Testing Practical Functions**
1. **Pouring Performance**  
   - When tilted for pouring, the water should flow smoothly in a solid stream and stop cleanly without "drooling" (dripping from the spout).  
   - The longer the water stream's "cohesive section," the better the pour design.

2. **Handling Experience**  
   - The teapot handle should provide a stable center of gravity and be comfortable and effortless to hold.  
   - Thin-walled teapots (1-2 mm) are lightweight but easily damaged; thick-walled teapots are more durable.

### 🛒 **V. Purchasing Channels and Tips for Avoiding Pitfalls**
- **Reliable channels**: Local Yixing studios, brand-direct stores, or reputable e-commerce platforms (supporting certificate verification).  
- **Certificate verification**: Confirm the authenticity of the maker's signature and professional title to avoid "contract-made teapots" (signed by a famous maker but not made by them).

💎 **Summary**
Choosing a teapot requires balancing five factors: authentic clay, beautiful form, fine craftsmanship, genuine attribution, and excellent functionality. Prioritize testing the feel in your hand and checking its functions, then make a decision based on your aesthetic preferences and budget. If you are pursuing collectible value, study the maker's background and the clay's characteristics in depth; for daily use, prioritize practicality and ease of care.
