When you cover a candle with a glass, it creates a limited supply of oxygen available for the flame to burn. As the flame consumes the oxygen inside the glass, it eventually uses up all the oxygen and goes out, extinguishing the flame.
If there is no oxygen, a burning candle will not be able to sustain the combustion process since oxygen is needed for the flame to continue burning. The candle will eventually go out in the absence of oxygen.
When the candle flame is covered with a flask, it creates a closed system where the oxygen supply is limited. The flame requires oxygen to sustain combustion, so when the available oxygen is used up, the flame goes out. The process is known as oxygen depletion, and it happens when the flammable material (wax) fails to receive sufficient oxygen to continue burning.
When a glass is placed over a candle flame, it acts as a barrier by cutting off the oxygen supply needed for combustion. Without oxygen, the candle cannot sustain the chemical reaction that produces the flame, causing it to go out.
The candle stopped burning after some time because it ran out of wax or oxygen. As the wax near the wick gets used up, there is no longer enough fuel for the flame to sustain itself. Additionally, if the candle is in a location with limited airflow, it may exhaust the available oxygen and extinguish the flame.

If a candle has no oxygen, its flame goes out.
It goes out
If there is no oxygen, a burning candle will not be able to sustain the combustion process since oxygen is needed for the flame to continue burning. The candle will eventually go out in the absence of oxygen.

If you put an enclosed container over a candle, after a few minutes or seconds, the flame will go out. This is because when the candle burns, it releases carbon. The air around the candle contains oxygen. The carbon and oxygen combine forming carbon dioxide. When there is no more oxygen to combine with, the flame goes out.

The concentration of oxygen in the air in the beaker becomes insufficient for the flame to carry on burning, or the carbon dioxide produced is trapped in the beaker, and the increased concentration causes the flame to be extinguished.
When a glass is placed over a candle, the candle flame burns up the available oxygen inside the glass. As the oxygen is used up, the flame is starved of oxygen and eventually goes out. This demonstrates the concept of oxygen depletion leading to extinguishing of the flame.

Light the candle and put a glass jar over it. Watch the flame of the candle closely. When the flame goes out, this means that the flame must have oxygen to burn the candle. This is how candles use oxygen.
