The Glass of Oriental Pearl TV Tower Is Cracked: Two Layers of Technology Lock The Safety, And Tourists Have "no Worries"

In the early morning of June 26, 2025, a video of "the glass of Oriental Pearl TV Tower TV Tower in Shanghai cracked" caused a heated discussion on the social platform. In the video, a small crack suddenly appeared on a piece of ground glass in the fully transparent suspended sightseeing corridor, and the photographer exclaimed in shock that "the foot just left and exploded", making countless netizens sweat for the safety of this landmark building.

This event has attracted the attention of many netizens on the social networking platform. Many people in the comment area showed their photos taken on the sightseeing glass of the Oriental Pearl TV Tower TV Tower.

However, behind this false alarm lies a precise game between modern architectural technology and materials science The tempered glass composite structure bonded by high-quality glass glue, with a "double insurance" mechanism, holds the lifeline of tourists under extreme conditions.

PART 01 The mystery of "self explosion" under high-temperature glass

At the time of the incident, Shanghai was experiencing sustained high temperatures of over 38 ℃. The cracked glass is located on one of the multiple layers of tempered glass in the sightseeing gallery. According to engineering experts' analysis, this crack may be caused by residual nickel sulfide impurities in the tempered glass manufacturing process undergoing phase transformation at high temperatures, leading to local stress imbalance. Although the self explosion rate of tempered glass already exists, this incident still sounds the alarm for the safety management of super high-rise buildings.

PART 02 The 'golden partner' of glass and glass glue

The most astonishing aspect of this incident is the "layered defense" mechanism of the glass composite structure. Only the middle layer of glass cracked, while both the outer and inner layers of glass were intact, and there was no peeling of the adhesive layer. This is due to the strong combination of two core technologies, glass and glass glue.

PART 03 The 'technological speed' from detection to replacement

1. Rapid isolation: Staff quickly and temporarily cover the cracked area and set up electronic fences to prevent tourists from approaching and ensure on-site safety.      2. Safety inspection: Through visual inspection and equipment testing, it is confirmed that except for cracked glass, all other glass structures are safe and reliable, and the sightseeing corridor remains open normally.      3. Customized replacement: Complete glass parameter mapping within 72 hours and initiate customized production of imported equipment from Germany. The new glass adopts an improved adhesive, and its self-healing function can automatically release the sealing agent when microcracks appear.

PART 04 The 'safety revolution' of super high-rise buildings

This incident has provided valuable experience for super high-rise buildings worldwide. The true safety does not lie in the glass not breaking, but in the power of technology supporting life even when it breaks. "From the laboratory to 468 meters high, this seemingly ordinary adhesive interprets the technological temperature of modern architecture with molecular level persistence.

Behind this false alarm is the perfect fusion of materials science and engineering art. In the future, with the continuous breakthrough of intelligent materials, we look forward to more 'invisible guardians' to safeguard urban safety.
