Most people will associate a microwave with warming food or beverages.
Yet, it’s important to look at what else a microwave can warm. Is it possible to warm specific materials that would otherwise not be heated?
A good question that people ask is, can you microwave pencil lead?
You cannot microwave pencil lead as it does not have a substantial amount of water content. Microwaves warm food, drinks, and/or any other item based on water content. Pencil lead is comprised of graphite carbon, which is not microwavable and can cause a spark in the appliance.
It is recommended to avoid putting pencil lead in the microwave. This is unsafe and not the right way to go.
This article will look at explaining some of the reasons you should not put pencil lead in the microwave.

Reasons To Not Put Pencil Lead In MIcrowave
1. Will Not Heat Properly
It’s common for people to want to put different materials in the microwave.
It’s essential to learn how to heat pencils safely and that is not going to be in the microwave. If you wish to heat a pencil in the microwave then that is a bad idea.
The reason has to do with it not working.
The microwave is engineered to work by heating water molecules in the item inside. This can be a plate of your favorite food, drinks, or anything else including a wet towel. If you place the item inside, it needs to be moist.
Unfortunately, the same does not apply to pencil lead.
It is going to be comprised of minimal water and that is not enough to warm it. This means placing the pencil lead inside a microwave might seem like a good option but it is not. At best, you are wasting your time and at worst you will ruin the appliance.
This is why it’s best to keep pencil lead away from microwaves. It is not the right way to go at all.

2. Can Cause A Spark In The Microwave
A major concern when putting pencil lead in a microwave has to do with sparking.
The appliance is not always going to do well with a pencil inside. This has to do with how the microwave reacts to the pencil as soon as the heating process begins.
This can include causing the microwave to spark.
This is dangerous and it will ruin the appliance. If you do put a pencil inside the microwave, you are risking the appliance and how it does under pressure.
Do not let this happen as it will do a lot of damage.
3. Not Enough Pressure
Some people think putting pencil lead in a microwave to make diamonds is possible.
This is false and it is something that has been passed down as a funny myth. It might seem possible but it is not.
This is unrealistic as there is not enough heating pressure inside the microwave for this to happen. If it were that easy, everyone would have the ability to create diamonds at home with nothing more than a microwave!
Instead, it requires tremendous pressure at the right temperature to create diamonds. This is why there are specialized companies that do this type of work while mining diamonds outdoors.

4. Will Ruin The Pencil
You are going to ruin the pencil.
This is one of the realities of putting pencil lead in the microwave. As soon as you do this, the pencil may be going to get exposed to excessive pressure which ruins it.
This means the pencil is not going to write the way it used to nor is it going to have the same shape. This is why placing a pencil in the microwave is a terrible option and one you should not be contemplating at all.
It will not work and you will ruin the pencil lead.
Final Thoughts
These are the reasons you cannot microwave pencil lead.
You cannot microwave pencil lead because it doesn’t have enough moisture content for the appliance to heat. It is also a catalyst for a fire in the microwave by causing a spark as soon as the appliance is turned on. It’s best to avoid putting any pencil in the microwave.
If you think it will be fine to place the pencil inside, you have to accept the risks associated with the process. This includes ruining both the pencil and appliance at once.
It is not a worthwhile experiment and it is going to ruin your microwave in seconds.
