China Built 10 Impossible Hotels… But There’s a Flaw Inside the Glass

10 of China's most audacious hotels, from a 40-storey exoskeleton in Macau to a mirrored sphere in Zhejiang, and the tiny flaw in their glass that engineers fear more than typhoons. Inside: how glass curtain walls work, how tempered glass is made, why nickel sulfide inclusions cause spontaneous glass breakage, the heat soak test, and the rules Shanghai and Guangzhou wrote about where glass curtain walls are allowed. Which one would you check into? Tell me in the comments. ⏱ CHAPTERS 00:00 The hidden threat inside the glass 01:25 #10 Morpheus, Macau 01:41 #9 Chimelong Spaceship Hotel, Zhuhai 01:53 #8 Grand Lisboa, Macau 02:01 #7 Sunrise Kempinski, Yanqi Lake 02:21 China's glass facade boom 02:40 How a curtain wall works 03:15 How tempered glass is made 03:48 Why China built icons 04:40 #6 InterContinental Shanghai Wonderland 05:20 #5 Sheraton Huzhou 05:56 Nickel sulfide: the hidden flaw 07:08 The heat soak test 07:31 Follow the money 08:45 Level 1: the street 09:24 #4 Hotel Éclat Beijing 09:53 Level 2: what inspections miss 10:40 #3 Tianzi Hotel 10:54 #2 Wanda Reign, Wuhan 11:08 Level 3: where glass is banned 12:02 The "weird architecture" crackdown 12:44 #1 Hilton Huzhou Nanxun 13:16 Two clocks 13:43 Recap ⚠ DISCLAIMER Educational commentary on architecture and engineering.
