To quickly assess the difficulty of the text, read a short excerpt:
20) has been obtained, remove it from the flame, and blow it to its final dimensions. A succession of gentle puff's quickly succeed- ing each other should be employed, in order that the progress of the bulb may be more easily watched and arrested at the right moment. During the process of blowing, the hot glass must be steadily rotated.
To collect the glass for blowing a bulb of lead glass, em- ploy the flame described on pp. 17-22 for heating lead glass.
If the tube be held horizontally whilst... the globe is blown, its form will most nearly approach that of a true globe. If it be held in the perpendicular position, with the mass of glass depending from it, the form of the bulb will usually be $o GLASS-BLOWING.
somewhat elongated. If it be held perpendicularly, with the mass of glass upwards, the resulting bulb will be flattened.
When a bulb is not of a sufficiently regular form, it may sometimes be re-made by re-collecting the glass, and re-blowing it. The greatest care is needed at the earlier stages of re- heating to prevent the glass from collapsing into a formless and unworkable mass.
