Why it worked
The video likely worked due to its satisfying ASMR-like visual of the glaze application and shaping process, combined with the aesthetic appeal of the 'slime' or dripping effect on the mug, which is visually engaging and fits popular trends.
Summary
The video shows a close-up of a person decorating a ceramic mug with a light-colored glaze. The glaze is applied from a squeeze bottle, creating a dripping effect around the rim of the mug. The person then uses their fingers to smooth and shape the glaze, and finally rotates the mug to show the finished decorative effect.
