I was given a Mathmos lava lamp on Freecycle recently and was wondering about it's construction . The bottle sits loosely on to the base and the 40 watt golfball bulb is in the base . When switched on the base which is plastic ( poss bakelite or similar) covered in aluminium gets very hot ...so hot you can only touch it for about a half second .There doesn't seem to be any way of ventilating the base . The bottle itself only gets warm .I was just wondering if there is a part missing between the base and the bottle .It doesn't seem right that the bottle sits loosely and also that the base gets so hot .
Does anyone here have one of these lamps ...does it also get very hot ?
