Double-Eye Glass Electrode — Historic Form
Twin small glass cups on a transverse bracket: one of the most striking specialist forms in the old catalogues.

A closer look.
A little piece of electrical sculpture
The transverse glass bracket is the thing that catches me first. Two small cupped ends turn one delicate glass object into something almost architectural, a miniature arrangement of balance and symmetry. It has that unmistakable old-apparatus quality: carefully conceived, slightly otherworldly, and far too interesting to disappear into an unlabelled box of spare glass.
Its place in the old catalogue
The two-headed design was named for both closed-eye regions in contemporary catalogues. It is offered here as a historical-form and collector enquiry.
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
Compare the branch spacing, cup angle and connection end. A matching title does not establish a match to your own handpiece.
Enquire about this form
Tell us the maker and model, add a photograph of your handpiece and the attachment you are trying to replace, and we can discuss identification, sourcing and availability. The exact example and connection details are agreed individually.
