Color-Altered Glass – Presented by Dwayne Anthony @ FOHBC 2012 Reno Expo


Would you put this notice on the FOHBC website and Peachridge Glass.
This should be a eye opener for bottle collectors as well as insulator collectors.

“Let’s look at a couple of examples of how greed affects our hobby: A simple CD 145 beehive insulator, embossed Postal, aqua in color, can commonly be found for sale in the $1-3 range. The exact same insulator subjected to radiation and altered to a stunning sapphire blue color was sold to an unsuspecting collector for $500.”

Dwayne Anthony

Dwayne Anthony, of Highland, CA, is an active bottle digger and has been collecting bottles and insulators since 1985. He began studying the effects of radiation and thermal exposure on antique glass insulators in the early 1990s. Shortly thereafter he teamed up with the National Insulator Association (NIA) to begin an ongoing educational program to assist collectors with identifying irradiated and thermally altered colors that are sporadically found in glass insulators. To aid in establishing an informative presentation and a comprehensive database, Dwayne has altered nearly 100 different glass insulator specimens and provided detailed reports on the results. He assembled a portable Altered Insulator Educational Exhibit that is shipped around the country to insulators shows, with all costs fully subsidized by an NIA educational fund. Due in part to these efforts, Dwayne has been awarded the National Insulator Association’s Outstanding Service Award and the distinguished Lifetime Membership Award.

Dwayne Anthony, with the support of the National Insulator Association, is pleased to offer this educational seminar concerning the effects of radiation and thermal exposure on vintage and antique glass. All discussion will be presented in an easy to follow format, with very little technical dialogue. The specimens exhibited during the seminar will be glass insulators from the mid/late 1800s to the early 1900s, however it should be noted that all collectible glassware can be susceptible to similar alterations. Collectors of antique glass in general, including bottles, should find this information informative, as well as thought provoking.
