A closer look.
Glass fingers, old ingenuity
There is something particularly lovely about a comb electrode. Each rounded finger turns the simple outline of a hair comb into a small feat of glassworking. In a fitted cabinet it brings rhythm to the arrangement, breaking up the smooth bulbs and long stems with a shape that feels instantly familiar and unexpectedly strange at the same time.
Its place in the old catalogue
The comb was the catalogue form associated with scalp and hair work.
A small piece of a bigger machine
The glass belongs to a larger arrangement of generator, resonator and handpiece. The head gives each form its distinctive working geometry: a broad face, a small cup, a row of fingers or a carefully curved stem. For a collector, those differences are part of the engineering story as much as the glowing glass itself.
Finding the right example
To identify a replacement, compare the number of fingers, their spacing, the overall width and the stem end. These details give each maker’s version its character.
