Lava Lamps For Sale – The Icon of The 60s Is Popular Again
The lava lamp was conceived in 1963 by Englishman Edward Craven-Walker. This cultural icon was extremely popular in the 1960s and 1970s and is regaining popularity today as an admired collector’s item. Differently shaped balls of wax in the lamp slowly rise and fall like lava, creating a mesmerizing, almost hallucinatory effect. Lava lamps for sale are available in many different styles, with a large variety of colors of wax and liquid. A lava lamp for sale will contain a standard incandescent bulb or halogen lamp of 25 to 40 watts. The bulb heats a tall, shaped glass globe containing water and wax. A glycerol-derived additive is often added to the water. The wax can be transparent, translucent, or opaque, and it is usually mixed with other substances such as carbon tetrachloride. The wax is slightly denser than the water at room temperature, but becomes less dense as the lamp warms because wax expands more than water when they are heated. It takes anywhere from 20 to 60 minutes for the lamp to heat up enough so that the wax becomes fluid. As its specific gravity decreases, freely formed blobs of wax rise to the top of the lamp, where they quickly cool and then descend. There is a metallic wire coil in the base of the globe that provides a surface tension breaker so the cooled blobs of wax can recombine at the bottom of the lamp after they descend. The manufacture of a lava lamp for sale is actually quite meticulous. Technicians measure the specific gravity of the various components in the wax and the water precisely and these specific gravities are individually coordinated for each lamp. Otherwise, the wax will just float on the bottom of the globe, creep up the side, or simply break up into small bubbles. As a result, each lava lamp for sale is actually custom-made. The ingredients used by manufacturers in the wax and water are closely guarded secrets. For this reason, it is very difficult to reproduce a classic lava lamp at home. According to one version of the story, Mr. Walker stumbled upon the lava lamp while he was working on a complicated egg timer during the early 1950s. Another version holds that he got the idea from a simpler liquid motion lamp he saw in a pub. Wherever the truth lies, Walker spent several years perfecting his product and eventually began marketing it through his Crestworth Company as the Astro Light. When sales dropped off in the 1980s, Walker sold the rights to Cressida Granger, whose company, Mathmos, continues to produce the lamps for the market outside the United States. In the U.S., two entrepreneurs from Chicago saw Mr. Walker’s lamp at a trade show in Germany in 1965. They acquired the U.S. patent rights and their company continues to produce the lamps in the United States under Lava World International. Nonetheless, Mr. Walker greatly enjoyed his cult popularity before his death in 2000. Lava lamps for sale symbolize a cultural icon of the counterculture generation that is regaining popularity today. Finding a lava lamp for sale can remind one of youth and freedom, or help show the younger generations what made the 1960s what they were.
