Bryan Katzel, vice president of product development at the lava lamp company Schylling, told Business Insider that the watery-looking base liquid is mostly a mixture of water, colored dye, and chemicals that prevent the formation of fungus. The other ingredient, which forms the psychedelic, slowly-changing shapes that float around the lamp, is primarily made of wax. In Schylling’s case, it’s paraffin wax, a petroleum-based wax that's commonly found in candles and cosmetic products. There is a big collectors’ community, and we still sell the original bulbs to fit the 1960s designs,” says Granger. For many of Rankin’s generation, the lamps are synonymous with student digs and late nights spent listening to Radiohead while staring at a lava lamp in someone’s bedroom. This was during a resurgence spurred by an Austin Powers-fuelled nostalgia trip, but most people probably associate them with the 1960s when they were invented. The first time that you use a liquid motion lamp, allow it to run for several hours to ensure that the wax is fully warmed and not simply flowing in straight, pillar-like shapes.
A. If a liquid motion lamp is used properly, it is very safe to use. The lamp can get hot during use, though, so it shouldn’t be handled when it’s illuminated. In addition, if you expose the lamp to extreme heat, it could explode, so keep it away from the stove, heaters, open flames, and any other heat sources. Despite the name, liquid motion lamps aren’t really intended for use as a light source. They do contain a light bulb, but it’s used mainly to heat the liquid and wax components inside the lamp to create the distinctive motion. Motion lamps don’t provide much in the way of illumination, so they aren’t suitable as task lighting. So why would you want one? The liquid lamp was invented in 1963 by Edward Craven-Walker, a British engineer. Anatomy of a Lava LampCraven Walker, who among other things, made underwater naturist films, owned a nudist camp in the New Forest, and he asked them both to join him there. When they arrived he asked if they would be more comfortable without clothes (they declined and “hastily buttoned up their coats”, says Granger.) The lamps grew in popularity, and Craven Walker’s reputation soared. At one point he invited the cast of the controversial musical Hair to his home, and they accepted – further sealing the lamps’ reputation as a must-have item for those who saw themselves as part of a counterculture. A liquid motion lamp features a clear glass vessel containing translucent liquid. This liquid usually consists of water and mineral oil. Coloured “blobs” made from a wax mixture are dropped into the liquid, and the vessel is placed on top of a base that holds an incandescent or halogen bulb.
He was originally inspired to invent the lamp after seeing it in a primitive form used as an egg-timer in the Queens Head pub in the New Forest. So basic was the manufacture of the original versions that Craven Walker used the bottle from a particular brand of orange squash, Tree Top, to make one of his early designs, the Astro Baby. In any decade other than the 1960s, it would have been categorised an 'executive toy'. Yet the Astro lamp, consisting of a bolus of wax heated by a light bulb, rising and falling in a tapered glass vessel of coloured liquid, was much more important than that. The 'lava lamp' as it later became known, with its Pop Art colours and obvious relationship with psychedelia, was to become a byword for the 1960s, selling by the millions. It became a major fad once a shop in Birkenhead announced Ringo Starr had bought one, and it received another sales boost after it appeared in several episodes of 'Doctor Who'.Because the wax and water mixtures have different densities, they don’t mix with each other. But if you’ve ever left an oil-based salad dressing sitting out for a while, you probably know that liquids with different densities typically end up settling in starkly defined layers. Why, then, does the wax in a lava lamp seem to have such a tough time deciding where it wants to be? Under these two names, the company has made lava lamps of largely unchanged design for more than half a century. It was, of course, a hot property through the 1960s and 1970s, but the cooling of the trend saw its manufacture sink to a mere 1,000 units a year by 1989. However, with the new Mathmos banner, and a little help from an 'Austin Powers'-inspired nostalgia for the 1960s, it was hot once more, selling close to one million units in 2000. The firm doubled in size for the next 10 years, she adds, and had something of a second heyday. The lamps appeared on the set of Channel 4’s The Word, Chris Evans’s TFI Friday and The Big Breakfast. To be a small part of something that is ingrained in the fabric of British society and culture feels quite special Rankin, photographer Not to sound trite, but you must always read the instructions on your individual lamp. Generally, manufacturers recommend leaving them on for a maximum of eight hours. After that, they should be allowed to completely cool and resettle. Aside from anything else, this will undoubtedly prolong the life of your lamp.
No matter what’s in there, we can all agree that lava lamps are uniquely mesmerizing. Want to take your viewing experience to the next level? Watch some wild GoPro footage from the inside of a lava lamp here. The bulbs in most motion lamps are usually 15 to 40 watts, so it can take up to an hour for the wax to heat enough to generate the trademark motion that makes motion lamps so interesting. It’s not exactly an accident that so few people have a clear idea of what’s inside a lava lamp, as manufacturers are notoriously tight-lipped about their top-secret recipes. Having said that, knowing how lava lamps work has definitely shed some light on what types of ingredients must be in there, and industry professionals have shared a few clues over the years, too. Just by looking at a lava lamp in action will tell you this much: There are two different substances in there that do not mix.Given all this, it’s astonishing looking around the factory in Poole that each bottle is still filled by a small but dedicated team of expert workers. New this year to the front of the factory is a showroom, displaying the whole Mathmos range. There, visitors (who must persevere if they want to find the hidden-away factory) can be dazed and amazed by an array of different designs, from the original Astro lamp to the 1.5m high floor-standing Saturn lamp. Don’t run your lamp for more than 10 hours at a time. It may become overheated, which could halt the free flow of the wax.
