LAVA STOPPED FLOWING 'WHY'

[blobby blobby bob]

hi everyone, please can anyone tell me why my lamp has stopped working, i bought a mathmos jet bottle three weeks ago (used), its a blue liquid with violet/pink wax looks stunning or did, anyway i have been useing it every night for around 5/6 hours per night for the last three weeks and it flows great with long strechy lava brilliant nearly the best flow iv seen then the othernight it just stopped, now all i get is a blob at the bottom it raises about 1/4 of the way up the bottle and sits there but its releasing little blobs does this all the time even from first movement not as if it gets to hot first.

anyway thats all its now doing looks awfull, so disappointing, i have tried a different bulb, was a 30 watt refector tried a 40 watt, i have put the bottle in another jet base as this sometimes works, i tried it in an early metal base as this does help different flow level but nothing, i have VERY carefully tipped it on its side whilst hot to move the lava it moves fine but still the same.

how can a lava lamp work just ace one minuite then just stop working, i love this bottle colourway so its a real shame if its no good.

does anyone have any ideas :o)

thanks to all :o) Darren

hi bohdan, thanks for replying, yes when hot the wax is in full contact all the way round the spring, its flowing but no as it was just a rise to 1/4 way up the bottle then its letting little blobs off the top they go up and come down so on so on does this all night, this bottle had such a great flow i dont understand it.

okay i will do all that and see what happens, out of interest how long does wax last, only whats the point in buying older/vintage lava lamps as most of the time these will have been well used, i understand mathmos state no more than 6 hours use in one day for all the size lamps except the lunar they say around 10 hours for that lamp.

shame if these lamps expire :o(

thanks for your help here :o) top man

cheers happy gooing :o)
