FROM CARDER’S NOTEBOOKS
Ed Bush of Painted Post, NY passes along this gem.
In about 1988 Bob Rockwell gave me a copy of a manuscript written by Harrison Hood that listed the colorants used in many of Carder’s glasses. Mr. Hood was a highly-regarded glass scientist at Corning Inc., and he probably obtained the information from Carder’s notebooks. I transcribed the manuscript exactly as written by Mr. Hood except for a few words I added that are enclosed by parentheses. I will send you the typed copy via another email, and you may use it in the Gazette if you wish.
