yes it does because the wick hardens
No, a candle does not lose mass when melting down. The wax that is melted simply changes from a solid to a liquid state, but the total mass of the candle remains the same.
No. -- Mass leaves the candle in the form of hot gases and soot, and there's always some of it left in the puddle of melted wax under the candle. -- Oxygen combines with the hydrocarbons in the candle material and the fibers in the wick, releasing chemical energy that leaves the candle in the form of heat and light.
Just like logs on a campfire or oil in an old-fashioned lamp, wax in a candle is actually fuel for the flame itself. The candle continues burning as long as there is wax to be melted & soaked into the wick. As it burns, the wax oxidizes into water vapor, CO2, and, of course, light. Wax continues to melt around the flame and soak up the wick to be used as fuel, causing the candle appear to "disappear" as we watch it burn.

No light has no mass its only an energy. There would be no way to capture it. Therefore light can not be melted. <><><><><> Actually, light does have mass, but that has nothing to do with whether or not it can be melted.
The mass of the initial candle is identical with the sum of masses of released gases from burning and the residues remained.
When a candle burns, it undergoes a chemical reaction called combustion, where the wax reacts with oxygen to produce carbon dioxide and water vapor. During this process, the candle's mass decreases as some of the wax is converted into gases. On the other hand, when a candle melts, it transitions from solid to liquid state, but its mass remains unchanged as no chemical reaction occurs.
Put the candle on a technical balance.

The two properties of a crayon that will stay about the same after being melted is it's color and mass.
This would most likely be the Easter Candle.
