Unfortunately the insulator wasn't sea glassed. It was in an antique store on the way to an off season shore point get away with my girlfriend. Nice Brookfield New York hive with a big underpour right under the embossing and in the inner skirt, lots of straw lines and some ghost embossing. We found some nice sea glass the day after the insulator find. Really like the cobalt apothecary bottle top and the piece of gray.
