Put the bottle on the base with the screw cap at the top. If it is not sitting straight please rotate a little. Then plug it in and turn it on. NB. It is normal for the glass to have small air bubbles and moulding scars.
Warm up takes between 1 and 3 hours depending on the size of the model and the surrounding temperature. Stalagmite shapes may form during the warm up process, these will then melt and the lava will begin to flow.
Your Mathmos lava lamp 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 do not leave your lava lamp on for more than six hours a day; this will prolong the life of your lamp.
Overheating will shorten the light of the life of the lamp. Overheating is occurring if there is either one large bubble or many smaller ones. Never move or shake the lamp when it is in use or still warm as this causes irreparable clouding. It is normal for the base to become very hot.
When your lava lamp 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 of operation. You can then buy a new bottle at www.mathmos.com in the current colours available. Please note we do not refill bottles and please on no account open the bottle or add liquids.
If the bulb blows please replace it with one of the same type and wattage. Only fit the correct bulb, as stated on the label in the base. Again bulbs can be bought at www.mathmos.com as can many replacement parts.
This lamp has passed the relevant safety standards and carries the statutory guarantee of the country of purchase. The liquid in the lamps are not dangerous and can be disposed of normally. Never use a lamp if the bottle has been dropped as this will create weakness in the glass, obtain a replacement bottle and dispose of the old one. Do not leave the lamp unattended with small children. If the liquid is swallowed by mistake drink plenty of water. If it is spilt onto the skin or had contact with the eyes pour on cold water. If any symptoms appear please visit a doctor.
