The iconic lava lamp was invented at the cusp of the swinging '60s by English accountant Edward Craven Walker. He came up with the basic design in 1963, inspired, so the story goes, by an egg timer in a local pub that was made from the pieces of a cocktail shaker. Originally marketed as the "Astro Lamp" by the Mathmos Company, the design caught on and was forever after know as the Lava Lamp.
The classic, authentic lava lamps we sell still operate in the same way as the original designs. An incandescent bulb in the lower base heats a colored wax material (we're partial to the red and the blue lava) in the tapered glass. As the material heats, it expands, causing it to flow up to the top, where it cools and then drops downwards. It's this heating and cooling repetition motion that is to mesmerizing and eye-catching.
There have been a few variations introduced over the years. Motion lamps have the same basic look, but have different glass shapes. Glitter lamps don't use the wax mixture. Instead, they rely on small reflective pieces of metal or other material that circulates around the glass. If you are a true fan, don't miss some of the special collector models. These original designs, issued regularly by the Lava Lamp company, come with a certificate of authenticity and are available for a limited time only. Used in a room along with other fun designs from our party lights collection, Lava lamps are a perfect way to bring fun look into your home.
