Made in the USA

Do not use oxalic acid to clean carnival glass, flashed amber, or use it on soft glass such as the Hemingray E-14B's and D-510's in opalescent milkglass. The Mexican CD 133.5 Tel Fed Mex seems to be made of very soft glass and is affected by oxalic acid. The acid will take any coatings off an insulator including carnival and flashed amber.

  • Glass Insulators

    Glass insulators were first produced in the 1850's for use with telegraph lines. As technology developed insulators were needed for telephone lines, electric power lines, and other applications. In the mid 1960's a few people began collecting these antique glass insulators. Today there are over 3,000 insulator collectors.


    All glass pintype insulators are classified in what is called the “CD Numbering” system of identification. This system was created and used by N.R. “Woody” Woodward, an early pioneer, researcher and author in the field of collecting glass insulators. The CD (Consolidated Design) numbers basically identify insulators by their shape and profile, regardless of exact embossed markings, glass color, or base type.
