Stemmed Glass Funnels Opened from a Blown Bulb

A filter funnel is a glass cone on a narrow stem: a folded filter paper sits in the cone and the clear liquid runs down the stem. Blow a bulb on a tube, cut the bulb open, spread it into a cone the shape of a folded paper, and the tube left below is the stem. The picture: a small glass funnel standing upside down, the opened bulb on its tube stem.
Juu
An hour per funnel, plus annealing
