This depends on what the materials are. If it is glass, for example, then a glassblower heats up glass and blows it as it cools to create the form and design they want. Metal vases are made from molds, and ceramic vases are made using a spinning wheel to quickly and evenly shape the material.
Ceramic is less damaging to your hair than other traditional hair appliances. Also, it heats up and cools down faster than most metal or glass hair appliances.
A convection current is created when a heated material continually rises, cools and sinks. Plate tectonics are driven by this type of motion,

When rock in the mantle cools, it becomes denser and can sink due to its increased weight compared to surrounding material. This process can lead to convection currents in the mantle, with cooler, denser material sinking and warmer material rising.

This is because of newtons law of cooling, the rate that the water cools is proportional to the difference between the temperature of the water and the temperature of the surroundings. So, as the water is hotter it cools faster, as it cools down the rate of cooling decreases.
The circular motion you are referring to is called convection. When warm material rises and cools, it creates a circular flow as it sinks back down to be reheated. This movement is driven by differences in temperature and density within the material.
The motion created when heated material rises, cools, and then sinks is called convection. This process is driven by differences in temperature and density, with warmer, less dense material rising and cooler, denser material sinking. Convection is a key process in transferring heat and energy within the Earth's mantle and atmosphere.
