由陈清宜（中国德化）研发的陶瓷杯子，2019年4月22日经世界纪录认证（WRCA）官方人员现场测量及审核，被认证为世界最薄陶瓷杯。 该陶瓷杯具有“白如雪、薄如纸、润如玉、声如罄”等特点，白度达到德化高白瓷的最高白度88.8度，薄度只有0.5mm，光照下，如蝉羽般细腻纹理丝毫毕现。它还可在杯底刻字，亦可在电陶炉上直接烧水煮茶，水烧开后水位线上杯沿不烫手，堪称世界陶瓷一绝。 该陶瓷杯已获得世界纪录认证公司特许授权，世界纪录保持者全球限量版陶瓷杯于世界纪录纪录陈列馆展示。

The ceramic cup, developed by Chen Qingyi (Dehua, China), is made of pure Dehua ore material, and has extremely thin walls less than 0.5 mm. Certified by the World Record Certification Agency official staff on-site, the cup has been recognized as the world’s thinnest ceramic cup.  This ceramic cup boasts characteristics such as “white as snow, thin as paper, smooth as jade, and resonant as a chime.” With a whiteness level of 88.8 degrees—the highest standard for Dehua white porcelain—and an ultra-thinness of just 0.5mm, its delicate texture reveals intricate details under light, resembling the translucency of cicada wings. The cup also allows for custom engraving at the base and can be used directly on an electric stove to boil water or brew tea. Remarkably, even when water reaches boiling point, the rim remains comfortably cool to the touch, making it a world-class marvel in ceramic craftsmanship. This exceptional ceramic cup has been officially certified by the World Record Certification Agency and is showcased in the World Records Museum as a limited-edition global masterpiece held by a world record holder.
