You can, but you need a mould, and heat.

Melting candle wax is a chemical change. Why? Because when you cook or burn candle wax it melts so it is a chemical change.

As a candle burns, the candle becomes smaller as the wax melts.
The hardening of candle wax is a physical change. This is because the wax simply changes from a liquid to a solid state without any change in its chemical composition.
The change of state is melting. When a candle wax is heated, it transitions from a solid state to a liquid state.
The melting candle wax dripping down the side of the candle is an example of a physical change. This occurs when the solid wax is heated and transitions into a liquid state due to the heat from the flame.
Some wax burns, and as it does so, chemical changes occurs. Wax converts to CO2, CO, and H2O. That is an exothermic reaction The rest of the wax melts with the increased temperature. That is the physical change.
For the wax, yes. It changes to a liquid and then back to a solid. But some of the wax is also consumed in a chemical change as it oxidizes, along with the burning wick.
The process that can change candle wax into carbon and water is combustion. When a candle burns, the heat from the flame vaporizes the wax, which then combines with oxygen in the air to produce carbon dioxide and water vapor.
The change of state in a lit candle is from solid (wax) to liquid (molten wax) to gas (vaporized wax) as the heat from the flame melts the wax and turns it into vapor that burns, releasing heat and light.
