Frequently Asked Lava Lamp Questions

We offer a range of replacement parts for many current and recent models, including bottles, bulbs, bases, caps, and other small parts.

Mathmos lava lamps are designed to last, with replacement parts available for many models. If you cannot find the part you need, please contact our customer service team.

If your replacement bottle does not fit your lamp, please contact our customer service team with your order number and details of your lamp. Subject to our Returns Policy, we can advise on exchange options.

The metal spring at the bottom of your lava lamp bottle is an essential part of the lamp and helps the lava flow correctly. If the spring becomes dislodged, run the lamp for up to six hours to allow it to settle back into place. This may need to be repeated if the spring does not settle on the first attempt.

Mathmos has been manufacturing high quality lava lamps in Britain since 1963. Our lamps feature a unique lava formulation developed to deliver superior flow, longer life, clearer liquid and more vivid colours. We also offer a comprehensive range of spare parts to help keep your lamp performing at its best for years to come. Every Mathmos lava lamp is designed to meet the highest safety standards and undergoes regular independent testing to ensure exceptional quality.

Stalagmite shapes are a normal part of the lava lamp warming up process. As the lamp heats up, these shapes will gradually melt and transform into the flowing lava effect. Once the lamp has reached its optimum operating temperature, the lava should begin to flow normally.

Mathmos lava lamp bottles are handcrafted, so slight variations in colour can occur. More commonly, the appearance of a lava lamp can vary depending on room lighting and screen display settings. Our product photos are taken to represent the colours as accurately as possible, but colours may appear different under different lighting conditions. For more information on how lighting can affect the appearance of your lava lamp, please see our blog article The Appearance of Colour.

Mathmos continues to use compliant halogen bulbs to heat and light its lava lamps, despite the phase-out of some halogen bulbs for general lighting applications. We are also exploring alternative technologies for future lava lamp designs should regulations change further. Our commitment is to keep Mathmos lava lamps in use for as long as possible by continuing to offer spare parts, replacement bulbs and ongoing support wherever possible.

Mathmos lava lamp bottles typically provide around 2,000 hours of operation, although many customers enjoy their bottles for much longer. The lifespan of a bulb can vary depending on usage and handling. Bulbs purchased directly from Mathmos are covered by a one year guarantee. Replacement bottles and bulbs are available on our website for many current and recent models.

Most Mathmos lava lamps can be used for up to six hours at a time. Exceptions include the Mathmos Candle lava lamps, which should be used for no more than four hours, and the Mathmos Saturn and Jumbo Jet Giant lava lamps, which can be used for up to twelve hours. Always follow the operating instructions supplied with your lava lamp.

The Mathmos logo can be found in several locations depending on the model, including the base, cap, cord label and, on most models, etched onto the bottle. Some bottles also feature the Mathmos name or logo moulded into the glass on the underside.

Mathmos lava lamp bottles are made in one of the highest quality automated glass factories in Great Britain. Small bubbles and specks in the glass are a normal part of the manufacturing process and are not a fault. They do not affect the performance, safety or lifespan of your lava lamp.

A small amount of wax at the top of your lava lamp bottle can occur as the lamp cools between uses and is not usually a cause for concern. If a large amount of wax remains stuck at the top during operation, the lamp may have overheated. Turn the lamp off and allow it to cool completely before using it again.

We currently don't upply the USA or Canada. However, a small range of our iconic Mathmos lamps may become available in the future. To stay in the loop, sign up to our mailing list here.

NB. Schylling Inc. owns the "LAVA" trademark in the USA and Canada. Mathmos Ltd is totally independent and not connected to Schylling Inc in any way.

A cloudy lava lamp bottle is usually caused by the bottle being shaken or moved while hot, or by the bottle reaching the end of its lifespan. If your lava lamp is cloudy, run it through a few normal operating cycles to see if the liquid clears. If the cloudiness does not improve, a replacement bottle may be required and can be purchased from our website.

The colour of a lava lamp bottle can gradually fade over time due to age, heat and exposure to light. To help preserve the colour of your lava lamp, keep it away from direct sunlight, strong natural light and other heat sources. If your lava lamp bottle is still under warranty and you have followed the care instructions, please contact our customer service team. Otherwise, a replacement bottle can be purchased from our website.

Mathmos has offered a wide variety of lava lamp colours throughout its history. While it is not possible for us to keep every colour in stock, we continue to offer a carefully selected range of lava lamp colours. We also occasionally release new colours and Special Fills, so we recommend signing up to our mailing list and following us on social media for the latest updates.

Mathmos does not offer custom lava lamp bottle colours for most models. However, custom bottle colours may be available for Saturn and Jumbo Jet Giant lava lamps. Please contact our customer service team to discuss custom colour options for these models.

Mathmos lava lamp bottles are sealed units and should not be opened or refilled. Attempting to add replacement liquid will void your warranty and may cause overfilling, increasing pressure on the glass bottle. For safety reasons, we do not sell lava lamp liquid separately. Instead, you can purchase a replacement lava lamp bottle with professionally filled contents from the Mathmos website.

Small air bubbles in the lava are normal, especially when you first receive your lava lamp. These bubbles will generally reduce as the lava lamp is used over time and do not affect performance.

If the wax in your lava lamp is stuck to the glass, try using the lamp a few more times. In most cases, the wax will gradually rejoin the rest of the contents. If the wax remains stuck and you have followed the operating instructions, please contact our customer service team. If your lava lamp is no longer under warranty, a replacement bottle may be required.

There should be nothing in your lava lamp bottle besides the lava, liquid and metal coil. Occasionally, you may notice small particles in the lava as it flows. These are usually dye particles from the manufacturing process and are not considered a fault. In most cases, they will become less noticeable over time. If you see anything else in your lava lamp bottle, please contact our customer service team.

Before recycling your lava lamp, consider replacing parts such as the bottle, bulb, base and cap. We offer spares for most Mathmos lava lamp models from the 1960s to today. If you own a Giant lava lamp, please contact our customer service team.

If recycling is necessary, please take the lamp to your nearest household recycling centre that accepts electrical waste.

The formula used in Mathmos lava lamps has evolved since the 1960s, improving resistance to clouding in heat and freezing in cold temperatures. However, the formula has remained unchanged in recent years.

If your lava lamp is not flowing:

Check that the bulb is working and is the correct wattage for your model.Ensure the lamp is positioned away from drafts, air conditioning and windows.Make sure the room temperature is at least 20°C.Allow the lamp to run for up to 4 to 6 hours, as lava lamps can take longer to warm up when first used.For older lava lamp bases, check that the correct bulb is fitted by referring to the bulb care and handling guidance for your model.Ensure the metal coil is present at the bottom of the bottle, as this is essential for proper lava flow.

To clean your lava lamp, use a glass cleaner and a soft cloth on the lava lamp bottle. The base and cap are made from either aluminium or zinc alloy, depending on the model, so use cleaning products recommended for these materials. If you are unsure, use a soft cloth only. Avoid abrasive cleaning products, as they can permanently damage your lava lamp.

Firstly, check our FAQs to see if your lava lamp issue is covered. If you still need assistance, all Mathmos lava lamps include a one year warranty, extended to two years when purchased directly from our website. If your lava lamp is within the warranty period, please contact our customer service team. For more information, please see our Faulty Product returns advice.

No, replacement screw caps for Mathmos lava lamp bottles are not available separately. The bottle caps are glue sealed and pressure fitted during manufacture. If your bottle requires replacement, you can purchase a replacement bottle from the Mathmos website.

If your lava lamp bottle breaks, carefully collect any broken glass and dispose of it safely. We recommend wearing gloves to protect your hands. Use paper towels or a disposable cloth to absorb as much of the liquid and lava as possible, then clean the affected area using methods appropriate for the surface. For specific cleaning advice, refer to the manufacturer's recommendations for your surface material.

Due to changes in manufacturing over the years, it is not always possible to identify the exact age of a Mathmos lava lamp. If you would like to learn more about your lamp, specialist resources such as flowoflava.com may be able to help.

Due to electrical safety regulations, we are unable to supply replacement lamp holders separately. However, replacement base and cap bundles are available for many models, and a wide range of other parts can be found in our spares and extras section.

A lava lamp works by gently heating a special wax formulation at the base of the bottle. As the wax warms, it becomes less dense than the surrounding liquid and rises. When it cools, it becomes denser and sinks again, creating the smooth, continuous movement that defines a Mathmos lava lamp. Mathmos has refined its lava lamp formula since 1963 to improve clarity, colour stability and long-lasting flow.

No. Lava lamps should not be moved or shaken while operating or when the bottle is still warm. This can cause the liquid to become cloudy and may affect the flow of the lava. Always allow your lava lamp to cool completely before moving it.

If your lava lamp is not flowing after storage or shipping, this is usually temporary. Following a long period of storage or transport, the wax may need several heating and cooling cycles to return to normal operation. Run your lava lamp for up to six hours at a time in a room between 20°C and 24°C. The flow should gradually improve as the wax and coil settle.

No. Lava lamps require a specific wattage and type of bulb to heat the wax correctly. Using the wrong bulb can prevent your lava lamp from flowing properly or may cause the bottle to overheat. LED bulbs are not suitable, as they do not produce the heat needed for proper flow. Please visit our replacement bulbs section to find the correct bulb for your model.

Yes, when used responsibly. Lava lamps should be kept out of reach of pets and placed on a stable surface. Like any electrical product, a lava lamp is best used under supervision.

If your lava lamp is leaking, switch it off and allow it to cool before handling. Wipe away any leaked liquid and check the bottle and base carefully. The liquid inside is not dangerous, but the lamp should not be used again until the cause of the leak has been identified.

Lava lamps offer a unique combination of ambient light, movement and colour. Their ever changing flow creates a captivating visual experience, making them popular for relaxation, creative spaces and interior design. Mathmos continues to make lava lamps in Britain today, drawing on decades of expertise.

Some people find the slow, repetitive movement of lava lamps soothing and visually engaging. Lava lamps are not a medical product, though they can contribute to a calm environment.

The liquid inside a Mathmos lava lamp is a high quality, water based formula that provides clarity and smooth wax movement. The exact formulation is unique to Mathmos and has been refined over more than 60 years.

No. We do not recommend leaving a lava lamp on all night. For best performance and longevity, operate your lava lamp for up to six hours at a time and allow it to cool completely before switching it on again.

Not really. Most Mathmos lava lamps use a low wattage bulb. The amount of electricity used depends on the model, bulb wattage and operating time.

No. All EU orders are shipped duty paid from our distribution centre in Germany. This means there are no additional customs charges, import duties or taxes to pay upon delivery.

Special Fills are one off runs, and Limited Editions are capped at specific production numbers. As a result, replacement bottles are not always available. These products are covered by our standard two year warranty.

Most Mathmos lava lamps are supplied with one bulb as standard. Occasionally, a complimentary bulb may be included due to the fragile nature of lava lamp bulbs and the risk of damage during transit. For specific details, please refer to the product page specifications for your lamp.

If your lava lamp is not working, the most common cause is a failed bulb. First, check the fuse in your plug and ensure the bulb is correctly fitted. If your lamp was supplied with a spare bulb, we recommend trying this as well.

Mathmos bulbs are covered by a one year guarantee. If all bulbs supplied with your lamp have failed within this period, please contact our customer service team for support. Should your bulbs have reached the end of their lifespan, replacement bulbs are available to purchase from our website.

No, Mathmos lava lamps are safe and designed to meet applicable safety standards. All Mathmos lava lamps undergo regular testing by independent bodies.

Lava lamps are designed to generate heat, which is essential for creating the flowing lava effect. During use, the bottle and metal parts can become hot, so always place your lamp on a stable surface and follow the instructions provided.

For best performance and longevity, use the correct bulb and do not exceed the recommended operating times.

Halogen bulbs are very delicate. Please find instructions relevant to your lamp here.

Most lava lamps should start working within one hour to an hour and a half from being switched on. First, they will form stalagmite shapes before the liquid lava formations. Please note that new bottles may take longer to heat up when new (up to three hours), but the time taken is expected to decrease after several uses.

Yes. We had these specially made to ensure our 60s lamps can still be enjoyed, see here.

Mathmos bottles are supplied with a lip that runs around the bottom of the bottle to ensure they sit straight in the base. When the bottle is placed on a base, it should fit securely, although it will still be possible to move the bottle from side to side, and a shadow gap may be visible. There have been many bottle and base size variations over time, so it may be possible with some much older products that a new bottle does not fit in the base. Please contact our customer service team for advice if your bottle isn't sitting on the base.

Please check that your bulb is working. You can purchase a new bulb here. Alternatively, please check the integrity of the fuse located in the plug.

Some lamps have a shadow gap between the base and the bottle; this is normal.

The coating on this bottle is very delicate; please take great care. Avoid rotating the bottle on the base as this can cause scratches.

Once your product has completely cooled, use the Allen key provided to unscrew and remove the back screw (keep these components safe). Holding the bottle and arm piece carefully, lift and remove the bottle and arm piece from the base. Carefully take the arm piece off the bottle. When installing the bulb, please only fit the correct type, as stated in the label on the base. You can install this by gently pushing them into the holder socket. Following a successful bulb change, please follow the instructions given previously in reverse to reassemble your lamp.

Most lava lamps should start working within one hour to an hour and a half after they have been switched on. First, they will form stalagmite shapes before the liquid lava formations. Please note that new bottles may take longer to heat up (up to three hours), but the time taken is expected to decrease after several uses.

The only suitable lava lamps for children are the Mathmos Neo Table range. The Neo lava lamp was developed with children in mind, so as well as looking stylish, it is also shatterproof, has fixture points, does not get too hot, and is screwed together as a secure unit. The lamp has also passed stringent safety checks required to be classified as child-safe, something no other lava lamp in the UK has a classification for. We recommend all other lava lamps be placed well out of reach of children under 14 years old.

The product must adhere to a stringent criterion to achieve this. For example, the bulb should not be accessible without a tool, it must be low voltage (not mains voltage), it must be very stable, it must have a shatterproof coating on the glass, the bottle must be fixed to the base, and it must not be too hot.

No. Neo has a unique formulation different from other bottles. This would overheat if used with other models. Contrastingly, Astro Baby and Telstar bottles will run slowly or not at all if used with the Neo.

The bottle has a shatterproof coating to help hold the glass together should this be dropped and broken. In this worst-case scenario, additional Neo bottles are available to be purchased here.

Replacement screws and Allen keys can be purchased for the Neo lava lamp here.

Once your product has completely cooled, use the Allen key provided to unscrew and remove the back screw (keep these components safe). Holding the bottle and arm piece carefully, lift and remove the bottle and arm piece from the base. Carefully take the arm piece off the bottle. Reverse this process to install the new bottle. Replacement bottles for the Neo lamp can be purchased here.

Try changing the bulb, replacement bulbs can be purchased here. Alternatively, please check the integrity of your power supply (from the plug to the lamp). Replacement power supplies can be purchased here.

Some lamps have a shadow gap between the base and the bottle; this is normal.

It is important to install the cap and rear arm element on top of the bottle before you position these on the base. Please see the 'Instructions' tab for detailed assembly guidelines on the relevant product page.

Yes, this is normal.

Yes. They do vary a little, and this can be normal.

Under no circumstances must the Neo Wall be installed in this way. The Neo Wall lava lamp is a low voltage (class III) product and must be connected to the included power supply to function safely and correctly.

A slight delay before the light comes on is normal with halogen bulbs. This is not considered a fault.

Candle-powered lava lamps should start flowing within twenty minutes after lighting. First, they will form stalagmite shapes before the liquid lava formations. Please note that new bottles may take longer to heat up; the time taken is expected to decrease after several uses.

For optimal performance, we recommend using tealights that are 15 mm in height, as tealights can vary in flame height, heating ability, and wick length. Mathmos tealights are recommended, but you can also use other high-quality tealights of the same size. For further recommendations, please check the product page under specifications.

Yes. Like any unprotected candlelight, you will need a place with no wind.

Firstly, please read the instructions carefully. Following any points that are relevant for all tealights.

DO NOT: leave unattended, leave on when going to sleep, use water to put out the flame, let debris (like part of a match) sit in the tealight, position near anything flammable, touch or move when lit, position near drafts, vents, children, or pets.

When the bottle is placed on a base, it should fit securely, although it will still be possible to move the bottle from side to side, and a shadow gap may be visible.

We do not recommend using these types of candles for this product.

Halogen bulbs are very delicate, please find instructions relevant to your lamp here.

Most lava lamps should start working within one hour to an hour and a half from being switched on. First, they will form stalagmite shapes before the liquid lava formations.
