lava lamps by Yvonne Bernal
The unique lamps were created by a British inventor and former World War II pilot, Edward Craven-Walker, who reportedly thought up the idea after seeing a homemade, liquid-filled egg timer at a pub.
In September of 1963, Craven-Walker started a company to research and develop his invention. But his widow, Christine Baehr, told BBC News they had a rough time, at first, trying to find investors.
But Baehr said that, after the couple took their product around the British countryside in a van, word of the wildly original illumination spread. Pretty soon lava lamps could be seen in Science Fiction movies and television shows like "Dr. Who," and became extremely trendy. By the mid-1960s, according to an MIT report, lava lamps "had exceeded 7 million units worldwide."
Baehr told The Associated Press that she knew the lava lamp had "made it" as a product when she heard that Beatles drummer Ringo Starr had purchased one.

No. There are no models available that can analyze a specific lava lamp and predict the pattern of the wax suspended in the oil. There are too many specifics that vary from one lamp to another. The specific position of the lamp in the base, for one. The continually varying temperature of the wax, oil, container, ambient surroundings. All of these things and more are involved in the creation of the patterns observed.
In 1963, a lava lamp typically cost around $20 to $25, which was considered quite expensive at the time. The lava lamp was a popular novelty item that gained popularity in the 1960s, known for its unique design and mesmerizing lava-like movement. The cost varied depending on the size and brand of the lamp, but the average price range was around $20-$25.

Yes it wont over heat its perfectly safe, you may go thru bulbs a bit quicker.

It depends on the size of the lava lamp
It is called a lava lamp because of its resemblance to flowing lava. The lamp contains wax or oil that moves in a mesmerizing way, similar to the slow movement of lava.
Well there is a metal springy at the bottom of your lava lamp, It helps heat the lava (wax) in the bottle.
A lava lamp is considered a mixture. It is a combination of oil, water, and wax that behaves as a solution when heated.
A lava lamp is an example of a suspension, where insoluble particles are suspended in a liquid and settle out over time. An emulsion, on the other hand, is a mixture of two or more liquids that are normally immiscible.
The Lava Lamp was invented by Edward Craven Walker and first went on sale in 1963. Walker was inspired by a lamp he saw in a bar 15 years earlier, and eventually perfected the "lava" recipe, using a combination of oil, wax, and various other solids. Originally marketed in Europe under the name Astro Lamp, it was eventually brought to the states by two American entrepreneurs and sold as the Lava Lite lamp.
I have a lava lamp from the 70's and it cost $20
The lava in a lava lamp rises and falls due to changes in temperature. If the lamp is not warm enough, the lava may not heat up sufficiently to flow downward. Ensure the lamp is placed in a warm area and allow some time for the lava to heat up and flow naturally.
The manipulated variable in making a lava lamp is the temperature of the lamp, which can be adjusted to control the movement of the colored blobs in the lamp.
A volcanic eruption is a living example of a lava lamp, where molten lava rises to the surface, cools, and solidifies. The cycle repeats as new lava continues to flow, resembling the movement of the liquid wax in a lava lamp.
