Ed Bush of Painted Post, NY adds his research information.
More regarding the green-threaded vase and perfume: At the Rakow Library there is a page of notes typed by J. Stanley Brothers, Jr., following his chance meeting in Washington, D. C., in 1948 with Frederick Bach, who had in the early 1900s been a cutter/engraver at Hawkes. Among other things, Bach told him the following: “Prior to 1914 Mr. Carder produced articles of clear glass which were threaded with color. The threading was wound upon the surface of the hot glass while it was still on the pontil rod. Colors of amber and green were used, the ware possessing the green threading being called ‘KILLARNEY.’ Hawkes cut some of this ware while Bach was still with the firm.”

Hawkes later produced ware with an engraved design they named Killarney which has no connection with the threaded Carder glass product.
