Vintage Glass Insulator
Photograph - Photography
American telegraph, telephone and electrical lines used glass insulators through the last half of the 19th century and the first half of the 20th century to insulate wires on the poles. These heavy pressed blobs of glass were most often clear or green glass, but other less common colors are choice for collectors. Manufacturers of fruit jars often manufactured insulators as well.
Glass insulators have become obsolete for their intended purpose( Telegraph & Telephone lines& electricity), with the introduction of more sophisticated technology and underground lines. They still exist in significant numbers, though, in antique stores and among collectors. Insulators can be used for light shades, suncatchers, salt and pepper shakers or other arts and crafts. Many of the crafts that use glass insulators require holes to be drilled in the glass, a specialized process that takes time and care.
