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.
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.

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.
This would most likely be the Easter Candle.
The total mass of the jar and its contents remains the same after the candle goes out, as long as nothing is added or removed from the jar. The mass is conserved in a closed system.
Physical changes are like cutting paper. The mass does not change. Chemical changes do not change total mass either. If you put a candle in a sealed container so that you may measure the total mass of the candle and the air before burning, then light the candle electrically but keep everything sealed, the total mass after burning will still be the same. But if you measure only the candle, then its mass has changed. So the mass of one single 'ingredient' will change during a chemical change.
This experiment is a verification of the law of the conservation of matter. And yes, the mass of all the combustion products would be equal to the mass of the candle and the oxygen it consumed while burning.
wouldn't make a difference if they were the same shape,mass,and volume
