Vintage Bulb Burning Out
 
I made a hanging lamp with a porcelain socket, and covered it with an old bottle I cut. I put a vintage edison bulb in the socket. After burning for about 20-30 minutes, the bulb burned out (I tried it twice). The socket and globe were hot. I assume the heat burned the bulb out...

Is it not possible to use a porcelain socket (heat)? Should I use a phenolic socket?

I like the look of the porcelain, is there another option similar to this?

Thanks in advance.

Got a picture.
Not likly it has anything to do with the socket.
Your trying to use a bulb that was never intended to be hung up side down so the support wires are not able to do there job.
Also if this is sealed with no vents it's over heating.
Ever notice every UL listed light fixture has the max rated wattage right on the socket?

There is a check ring and strain relief at the top. Top has no vent, but bottom is open.

The bulb is a 40w

Try a fan duty candilabra style bulb.

Heat rises. Without a vent at the top, heated air is going to collect at the top of the fixture. Would it be possible to drill some holes in the neck of the bottle? Or somehow open up the stopper where the cord comes in.

Or find a lower wattage bulb.

Are you certain the bulb is correct? What is the voltage listed on the bulb (lamp). 40 watts at what voltage?

The bulb is 40w, 120 volt
