I'll guess you're looking at an old Western Union line. Both those insulators were their standard type for a while -- beehive from about 1884 through 1911, and the Hemingray 42 would have been from the 1920s.
Kyle's given you great info on cleaning. I prefer lye myself, which is usually available at any hardware store, Home Depot, etc. I make up a fairly weak solution and let it soak for at least 24 hours or more. The lye or oxalic acid will soften the black soot and let you scrub it off.
Be sure to use a scrubber that won't scratch the glass. Ordinary green Scotch-Brite can abrade glass. I use the blue "no-scratch" Scotch-Brite.
