Thanks to Steve Bobb for his Sept 14 additions to the Lightning Rod and Threadless Insulator gallery, of the high quality photos he took at the Sandwich Glass museum. They haven't changed that display in years and there are a couple of issues with it. The most obvious should be their identification of 1850s style 'egg" telegraph insulators as "1890s Insulators". But another is what they are calling an insulator mold. It looks more like the mold for an early, threaded shank drawer pull (did somebody say "bureau knob"?), possibly 1830's date. The photo here shows those same type of early drawer pulls(2 3/4 x 2 3/8). The mold is shown upside down, probably to better display what they are calling an insulator, and the bottom of the mold is missing. What is pressumed to be the skirt of an insulator is the funnel part of the mold where the molten glass would be poured in and then the plunger inserted to force it into the main cavity that formed the object. No glass would have remained in the funnel. The base of the mold would have had a recess to form the head of the drawer pull but as shown in the museum display, that is missing and the mold is open.. There are probably a lot of new insulator discoveries waiting to be made but don't hold your breath any longer on this one turning up.
