Keep the cable away from heated surfaces.

For best performance, we recommend you keep the product away from sunlight to prevent fading, drafts and cold places to prevent slow operation and freezing, hot places to prevent overheating.

Place the base on a stable and flat surface. OPTIONAL: The base has x 4 screw holes that allow you to fix it (if required) onto a suitable surface. We recommend you use suitable screws (x 4 of the same specification) for the desired surface you will be fixing the base onto. You must ensure the base is positioned safely onto the desired surface.

SET-UP

This product comes with 8 components:

  1. Base
  2. R7s Bulb
  3. Glass Shield
  4. Heat Ring
  5. Bottle
  6. Cast Metal Cap
  7. M4 Screw x 2
  8. Allen Key x 1

To Assemble:

Avoid handling bulbs with your bare hands, instead, use a soft cloth or similar.

  1. Fit the bulb into the product by pushing one end in and springing it into place between the lamp holder contacts. Ensure that each end of the bulb is sitting properly in the lamp holder.
  2. Fit the glass shield in position. This part must be fitted in place before use.
  3. Fit the heat ring in position as shown.
  4. Carefully lift the bottle by the neck and place the bottle onto the heat ring from the front of the product. Ensuring it is vertical and stable.

WARM-UP

Warm-up takes between 1-3 hours depending on the surrounding temperature. Stalagmite shapes may form during the warm-up process, these will then melt and the lava will begin to flow.

OPERATION

  • Your Mathmos product will operate best after it has been used four or five times. For the first few times, you may see small air bubbles in the lava. Please note the heating time will decrease after several uses.
  • Please do not leave the product on for more than six hours a day or allow it to overheat; this will prolong the life of your product. Overheating will shorten the life of the product; if it is overheating there will be either only one large bubble at the top of the bottle or a lot of very small bubbles.
  • Never move or shake the product when it is in use or still warm, as this causes irreparable clouding.
  • It is normal for the glass to have small air bubbles and moulding scars.

REPLACEMENTS

When your product has ended its life it will begin to go cloudy, the colours may fade and it will not move as well as it once did. This will happen after approximately 2000 hours in operation. Whether your product has ended its life or when you wish to have an alternative colour combination, visit our website at www.mathmos.com for more information on a replacement bottle or full product. Please note we do not refill bottles. Please on no account open the secure cap and add liquids.

If the bulb blows, please replace it with one of the same type and wattage. Only fit the correct bulb, as stated in the label in the base. Visit our website at www.mathmos.com for more information on replacement bulbs.

IMPORTANT! Always allow your product to cool down completely prior to handling or moving the product. Once your product has completely cooled, using the allen key provided to unscrew and remove the side screws (keep these components safe). Carefully, lift the cap off. Lift and remove the bottle from the base.

Place the replacement bottle onto the product. Now refer to ‘set up’ for instructions on how to assemble.

    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 56 years of British manufacturing excellence to draw 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.

  14. Q. What is Mathmos doing about halogen bulb phase out?
    A. Don’t worry whilst some halogen bulbs are being phased out for lighting purposes Mathmos uses halogen bulbs primarily to heat its lava lamps rather than to light them; so the use of halogen bulbs in our lava lamps is part of a special purpose exemption under current regulations.

We also have alternative ways of powering our iconic lamps should there be further changes to the regulations in the future.

  22. 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.

    liquid low - liquid refill - top up liquid

  23. 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.

  25. Q. Why can I see a metal spring coil floating in my lava lamp bottle?

  26. Q. Why can I see a foreign object in my new lava lamp bottle?
    A. There should not be anything other than lava and liquid in the bottle, please contact customer services here.

    A.
    1. Check your bulb is working

    3. Make sure the room is at least 20 degrees centigrade.
    4. The lamp will take longer to warm up the first few times; run the lamp for 4 – 6 hours each time.
    5. If you have an older base check the correct light source is fitted: see bulb section for the possible bulbs here.
    6. Check there is a coil at the bottom of the bottle.
  41. Q. What should I do if my lava lamp has been moved while being on and is now cloudy?
    A. Clouding in a bottle which has been moved when it is in use or still warm is irreparable. You can try and run the bottle for a few times to see if this will improve it. If this does not help, you can buy a new bottle here.
