A. Yes Mathmos lava lamps are designed to last please buy replacement parts here.
Q. My lava lamp is faulty what can I do?
A. Firstly read through these FAQs to see if your question has been answered. If not we offer a one year warranty on all our products. If your lamp was purchased less than a year ago, please contact our customer service team who will be happy to assist. Please read our Faulty Product Returns Advice.
Q. Why does my lava lamp have specs and bubbles in the glass?
A. Mathmos lava lamp bottles are manufactured in one of the highest quality automated bottling factories in Britian. Even so small bubbles are a normal part of this manufacturing process, it is not a fault.
Q. What are the differences in quality between a Mathmos lava lamp and others?
A. A different lava formulation giving better lava flow, longer life, clearer liquids and more vivid colours. The metal parts are of a thicker, higher grade metal allowing us to hand polish them to a high shine. Our bulbs are directional taking the heat away from the base and directing the light into the lava. We have a higher standard of safety and build quality audited by a number of different bodies. We provide a comprehensive range of spare parts unlike other throw away products. We have 50 years of British manufacturing excellence to draw on.
Q. How long should it take for my lava lamp to warm up?
A. Lava lamps should start working within an hour to an hour and a half of turning them on. First they will form stalagmite shapes, then they will start to form lava lamp shapes. Please note, new bottles will take longer to heat up (up to three hours), but the heating time will decrease after several uses.
If your lava lamp does not warm up in this time it may be positioned in the wrong place or the room may be too cold. Lava lamps should be positioned away from drafts and air conditioning. The room should be at least 20 degrees centigrade.

Q. My lava lamp just has one large bubble sitting at the top of the bottle that does not move?
A. The lava lamp is overheated. It could have been on too long (more than 8 hours), so please turn it off and allow it too cool. Or it is positioned in a room that is too hot (more than 24 degrees) or next to a heater. Please reposition your lamp.

Q. How should I dispose of my lava lamp bottle when it reaches the end of its life?

Q. Why is my Astro bottle not sitting straight in the base?
A. Bottles are now supplied with a lip which runs around the lower part of the bottle, to ensure it will sit straight in the base. When the bottle is placed on the base, it should sit securely, although it will still be possible to move the bottle from side to side. If your bottle isn't sitting correctly, please please contact our customer service team .

A. Small bubbles in the lava are normal particularly when you first receive the lamp. As you use this over time the bubbles will reduce.
Q. Why has the liquid in my bottle gone clear?

Q. The liquid level of my lamp is too low. Can I top it up?
A. No Mathmos lava lamp bottles are sealed units. Do not attempt to take off the cap and on no account top up the liquid. The heat from a lava lamp causes the liquid to expand and topping it up could cause the lamp to be overfilled and put pressure on the glass as the liquids expand. If you are not happy with your bottle buy a new one here.

Q. Why is there wax sticking to the side of the bottle?
A. If you use the lamp a few times this wax should join the rest of the lava. If this does not happen and your lamp was bought less than a year ago please contact us here. If you lamp is over a year old please buy a replacement bottle here.
Q. Do you offer any colours in addition to what is shown on your website?
A. No however we do constantly add new colours so sign up to our mailing list to be notified of new colours as they are released.
Q. Why can I see a metal spring coil floating in my lava lamp bottle?
A. The metal spring is an essential component of a lava lamp bottle. However it should be sitting at the bottom of the bottle. Run the lamp for several hours and hopefully the spring will settle in its right place.

Q. Are Mathmos lava lamps suitable for children?
A. The only lava lamp suitable for children is the Mathmos Neo. The Neo was designed with children in mind, so as well as looking stylish it is also shatterproof, has fixture points, doesn’t get too hot, and is screwed together as a secure unit. This means the lamp has passed the stringent safety checks needed to be classified as child safe, something no other lava lamp in the UK is classified as. We recommend other lava lamps be placed well out of reach of children under 14.
age limit - kids
