Painting a Snuff Bottle from the Inside through Its Narrow Neck｜畫家把筆伸進鼻煙壺裡，反著畫在透明內壁

大都會藝術博物館介紹鼻煙壺內畫，藝術家以細而彎曲的工具穿過狹窄瓶口，在透明玻璃或水晶內壁繪畫。圖像的位置使製作動作必須從有限入口深入器物內部。

inside painting developed into multiple schools and tools, and not every transparent snuff bottle uses this technique; the general craft description should not be projected onto unrelated bottles.
