《紫砂的密码》第二集：紫砂的成型和烧制工艺

Discover the handcrafting and firing secrets behind authentic Yixing Zisha teapots! In Episode 2 of "Secrets of Zisha" (紫砂的密码), we take a step-by-step deep dive into the complete artisanal process behind authentic Yixing pottery—from raw clay mesh preparation to hand-shaping and kiln firing. From traditional hand-slapping (拍泥片) and "Mingzhen" (明针) surface burnishing to scanning electron microscope (SEM) testing at the Jiangsu Ceramic Research Institute, explore how clay crystal alignment, double-porous structures, and high-temperature firing (1080°C–1250°C) distinguish real handcrafting from modern mass-produced slip casting. 📌 Chapter Timestamps: 00:00 Introduction: From Raw Ore to Finished Teapot 00:57 Step 1: Clay Preparation & Particle Mesh Grading (制泥与目数) 03:11 Step 2: Traditional Hand-Pounding & Slab Assembly (手工打接镶嵌成型) 04:38 Step 3: The "Mingzhen" Smoothing Craft & Microscopic Pore Analysis (明针工艺) 06:10 Handcrafting vs. Modern Mechanical Shaping: Jiche, Roller Pressing & Slip Casting 07:58 Step 4: Kiln Firing Science, Temperature Limits & Shrinkage Rates (烧制工艺与温度) #YixingTeapot #Zisha #PurpleClay #HandmadeTeapot #Mingzhen #GongfuTea #ChinesePottery #CeramicArt
