Small Cataphoric Glass Electrode — Historic Form

A closer look.

The detail that changes the object

At first glance it is another slim piece of glass. Then the recessed end comes into view and the whole object tells a different story. This is the sort of detail that makes an incomplete set worth studying properly. A modest change of shape can identify a particular branch of the maker’s catalogue and turn an anonymous attachment into an object with a name and a place.

Its place in the old catalogue

Master described an indented surface for a medicament-bearing pad. That is the historical meaning of this cataphoric form.

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

The small recessed head and its angle matter when identifying this type. Enquiries are for the historical form, collector completion and possible sourcing; no medicine or treatment kit is included by this entry.
