Placing a candle under a glass container will cause the flame to consume the oxygen inside the container. As the oxygen is used up, the flame will eventually extinguish due to lack of oxygen, creating a vacuum inside the container.
Putting a glass jar on a candle can create a greenhouse effect that traps heat, potentially causing the glass to crack or shatter from the heat. It can also increase the risk of a fire starting if the candle is left unattended. It is not safe to place a glass jar directly over a burning candle.
To clean candle wax out of a glass container, place the container in the freezer for a few hours. Once the wax is frozen, use a butter knife or similar tool to pop out the wax. Alternatively, pour boiling water into the container to melt the wax and then wipe it clean with a paper towel.
Melt it all the way down and pour out the unused candle wax, then clean the jar with Hot Soap water. You may have to scoop or dig out some wax that may be left in the jar. There is a less messy way to do this job. You put the candle in the freezer. The molecules will constrict and the candle should pop right out. No messy melted wax or scraping. It works most of the time. Some candles need a little more prying than others.
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 blackening of the glass rod is due to the deposition of soot (carbon) from the candle flame onto the surface of the glass rod. This is a physical change where the soot particles adhere to the glass surface but do not chemically alter the glass itself.

Yes, the material and size of the container can affect how fast a candle burns. For example, a small ceramic container may retain heat and cause the candle to burn faster, while a larger glass container may allow for better airflow and slower burning.
Use old candle wax , melt it down pour into glass container and let harden. Or you can try melting old newspaers with candle wax for a unique creation.

Lifting the glass tumbler placed over a burning candle to a height of 1cm could disrupt the airflow around the candle, affecting its ability to receive oxygen. This may cause the candle flame to flicker, decrease in size, or even extinguish depending on how much air is allowed to reach the flame.
It depends on the thermal energy, by knowing how much heat is being transferred. Also, it does depend on the type of container. If you have a plastic container or foam container, the heat will not transfer as fast as it would if the heat was in a glass container. Or instead of using the word heat you can refer to that word as a candle giving off heat if placed in any type of container to perform the science experiment.

Glass candle holders are generally the easiest to clean. Unlike metal, they can be placed in the microwave for 30 seconds to soften the wax.
The edible life will vary significantly depending upon what food is in the glass container, how it has been handled and what the microbiological load was when it was placed in the fridge.
