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
?

I don't pick it up when it's on but I will go and have a look at it
now...

OK ours says "danger too hot pls don't touch"

So there you go, don't touch it.

Thx for that . I guess if you had kids youd keep it well out of reach
..
Can I ask about the bottle .Does it just sit loosely on the base ?

If it didn't get hot, the wax wouldn't melt, and it wouldn't work.

Yeah I had managed to figure that out but unless you own a lava lamp
you will not know how hot it does get .It is VERY hot ,hence my
question..

Yerbut isn't the heat meant to go up towards the lamp & not out through the
base? My daughter had one & I don't recall that getting hot.

I have two - the glass gets warm, the bottom of the base gets hot, the
top half of the base gets very hot.

Mine has a small REFLECTOR type bulb, 39mm I think. This must help with
making the heat go where it's wanted - into the bottle rather than out the
sides. The whole base does get hot though.

Simon.

Both mine came second-hand from ebay and neither had reflecting bulbs in
place. Reflector bulbs make sense.

It's hard to tell from the website what type of bulb they supply as a
replacement but the label inside the base has a diagram showing a
golfball shape bulb and it says 40 Watt
