I there a safe way to separate the glass bulb from the metal part of a lightbulb?
To open a light bulb, twist out the metal solder point on the bottom of the bulb with a pair of pliers. Hold one side of the black glass insulator with your pliers, then twist it up to break the glass apart. Remove the broken bits of insulator glass and break off the interior tube with a flathead screwdriver
CAUTION this is not a smart thing to do!!
I'd really, really, REALLY advise NOT to try it.
Just don't do it with the new lightbulbs that contain mercury, obviously.
Hi Kathryn, hope this video helps you out,
Not sure why you would want to do this, what is your project?
This is a wikihow tutorial that starts off with the information the Dee posted, but there is a lot more detail with pictures and further instructions. This should help. Wishing you the best.
