The four sides of the bottle body are symmetrically decorated with ears, and the glaze color changes, blurred and dazzling. Kiln-changing glaze means that when the utensils are fired in the kiln, due to the oxidation or reduction of various color elements in the kiln, the kiln will show unexpected glaze color effects. Because its appearance is accidental, its shape is special, and people don't know its principle, but only know that it is obtained from the change of the roasting process in the kiln, so it is called "kiln change", which means that it is unpredictable and unique. The bottom is engraved with "Yongzheng Year System" four-character seal script. 瓶身四面，對稱飾雙耳，釉色窯變，迷離炫目。窯變釉即器物在窯內燒成時，由於窯中含有多種呈色元素，經氧化或還原作用，出窯呈現意想不到的釉色效果。由於其出現出於偶然，形態特別，人們又不知其原理，只知於窯內焙燒過程變化而得，故稱之為“窯變”，謂其變化莫測，獨一無二。底刻“雍正年制”四字篆書款。
