Lava lamps are widely used for decoration purposes rather than lighting since they were on the market. The movement of the candle in a blob is mesmerizing, which makes the audience calm and creates an enchanting picture. The candle moves in the form of a lump in the lamp, which makes it a Lava lamp. They are sold in various shapes and sizes. Different wax colors are also available.
This works with an exciting process. This Lava lamp has an incandescent or halogen light bulb that warms a glass tube containing water and translucent or a thick mixture of wax and carbon tetrachloride. There are many formulas, but these are the most widely used.
The candle is denser than water at room temperature, while when it becomes a candle, it is warmer. The wax finally melts into liquid and moves to the surface in the form of a lump. Clots gradually cool down.
25 to 40-watt bulbs are used frequently. It takes a candle for about three hours to melt and form into clots. When the lights start working, we need to make sure there are no sudden movements. Sudden vibrations can cause emulsifying two liquids, which means clumps are not bright and not clear.
As soon as the lights start working continuously, always be careful so that nothing shakes the lamp because the liquid can emulsify, and this will produce clots that are unclear and cloudy. To fix it, we need to take a lava lamp and leave it for some time.
The inventor was a British-born Singaporean Edward Craven-Walker in the 60s. He started a company called Crest worth located in Poole, Dorset, England. Lights gained enormous popularity in the 60s and 70s and were a great success for decades.
In the late seventies, Spector sold Lava Simplex International to Eddie Sheldon and Larry Haggerty from Haggerty Enterprises. Haggerty Enterprises continues to produce and sell Lava Lights in the US, using the world name-Lava. “Lava lights” have been used as a general term, but the world of Lava has claimed trademark infringement.
World of lava has shut down production in the US and surrendered their lights to China. In the 90s, Craven-Walker, who had rights to Britain and Western Europe, sold his rights to Cressida Granger, and his company, Mathmos, continued to make Lava Lamps and related products. Mathmos lights are still made at the original factory in Poole.
