Different from all the other clear 230's you find. This guy has the white spot inclusions in the glass like the amber ones do and is packed with pin point fizzy bubbles. White spots in the skirt, base, threading and the trough of the wire groove. The spots are not super concentrated like some, but they are still very noticable. This insulator is best baselighted or displayed in bright light to show bubbles and spots best. VVNM. $13 + shipping.
