How To Open A Geode In Microwave?

What is a Geode?

A geode is a type of rock that is found in nature. It typically has a hollow center that is filled with crystals or other minerals. 

Geodes can be found all over the world, and they come in many different shapes and sizes.

The word “geode” comes from the Greek word for “earth”. This is because geodes are found in the earth, and they get their name from their appearance. Geodes can be brown, black, or gray, but they often have a beautiful crystal interior.

Geodes are formed when gas bubbles get trapped in solid lava. Over time, the gas bubbles will slowly dissolve, leaving behind small pockets of air inside the rock. The crystals that grow inside these pockets will often be very beautiful and intricate.

Geodes are a popular type of rock to collect, and they can be found at rock shows, in gift shops, and even at some gas stations. 

They make a beautiful addition to any collection, and they are also a great way to learn about crystals and minerals.

How to microwave a geode?

There is no one-size-fits-all answer to this question, as the best way to microwave a geode will vary depending on the size and type of geode. However, as a general rule, it is best to microwave a geode for around two minutes on medium heat.

Before microwaving a geode, make sure that it is completely clean and free of any dirt or debris. You may also want to use a wire brush to remove any loose crystals from the surface of the geode.

Once you have ensured that the geode is clean, place it in the microwave and set it to medium heat. Microwave for around two minutes, or until the geode has heated up sufficiently. Be careful not to overcook the geode, as this can cause damage to the crystals inside.

Once the geode has been microwaved, allow it to cool down before handling it.

Things to remember

However, there are some things you should keep in mind if you choose to microwave a rock.

  • First, make sure the rock is clean and free of any dirt or other debris. You don’t want to contaminate your food with anything that isn’t supposed to be in it.
  • Second, use a moderate amount of power when microwaving the rock. You don’t want to blast it with too much heat, or you could end up damaging your microwave.
  • Third, be patient. It may take a while for the rock to heat up fully. Let it cook until it’s hot to the touch.
  • Fourth, be careful when removing the rock from the microwave. It will likely be hot, so you don’t want to burn yourself.
  • Fifth, consider microwaving the rock in increments rather than all at once. Microwave it for 10 or 15 seconds at a time and then let it set for about 30 seconds before continuing. 

This should help ensure that your food is fully cooked without damaging the microwave.

What are the different ways to open a geode?

There are a few different ways that you can open a geode. One of the easiest ways is to use a hammer and chisel. Another way is to use a drill. You can also use a knife or scissors to cut the geode open.

If it’s just sedimentary or vesuvianite, then cut into its side with a knife at an angle so that there are two halves. Then use a hammer to make the crack bigger until you can pull them apart. 

If possible, try not to use your hands/fingers because they might get hurt. Alternatively, break one half by hitting it horizontally over a hard surface.

Chisel and mallet

If it is a quartz geode, then use a chisel and mallet to make a starting point for breaking it open. Hit the chisel with the mallet to break the quartz and then pry the two pieces apart. Again, try not to use your hands if possible.

Rock tumbler

You can also use a rock tumbler to break the geode open.Another option for opening a geode is to place it in a rock tumbler. 

A rock tumbler is a machine that is used to polish rocks. It typically consists of a drum that is filled with rough rocks, water, and a polishing compound. 

The rocks are rotated in the drum for a period of time, which causes them to polish each other. 

You can also use a rock tumbler to break open geodes. All you need to do is place the geode in the drum and let it rotate for a few minutes. 

The force of the rocks hitting the geode will cause it to break open.

Whereas you can also place the geode in a fire and let it heat up until it breaks open.

Geode cracker

However, the most popular way to open a geode is by using a geode cracker. 

A geode cracker is a tool that is specifically designed for breaking open geodes. It has two metal rods that are placed on either side of the geode. 

When you apply pressure to the top of the tool, the rods will penetrate the geode and break it open.

Be careful when opening a geode, as the crystals inside can be sharp. Make sure to wear gloves when opening a geode, and avoid cutting yourself on the crystals.

Make sure that you are wearing safety goggles when you are using this method, as there is a chance of the geode shattering and sending fragments flying in all directions.

What happens when you put geode in the microwave?

When you put geode in the microwave, the heat from the microwaves will cause the water inside the geode to vaporize. 

This will cause the pressure inside the geode to increase, and eventually, the geode will explode. So if you have a geode that you’re not sure is hollow or not, it’s best not to put it in the microwave.

When you put geode in the microwave, the water inside the geode heats up and starts to steam. This causes the pressure inside the geode to increase, and eventually the geode explodes. 

The force of the explosion can cause pieces of the geode to be sent flying across the room, so it’s best to do this experiment in a safe place where there is nothing breakable nearby.

The good news is that most geodes are not actually hollow. They usually contain some small crystals or minerals inside of them. So even if your geode does explode, it’s not likely to cause any damage.

Microwave ovens are known to be harmful, especially to water-containing items like geodes. When you put them in the microwave is when something bad may occur. 

According to Wise Geek, after microwaving your geode for 10 minutes, there is an increased chance that it will explode. The minerals inside your geode can heat up and cause it to explode violently.

Is it dangerous to microwave a rock?

Microwaving rocks is not dangerous if you take proper precautions when doing so. 

 Rocks can be made of many materials like glass, crystals, and various compounds. These things can microwave very differently and potentially become dangerous if microwaved.

Rocks that are not porous would not absorb the microwaves; meaning it would just reflect off of the rock and into your oven. It might cause damage to your oven though! 

Glass and crystal rocks could shatter from the pressure that builds up inside them during microwave cooking, especially if they have been subjected to heat or cold repeatedly over time as this can weaken them. 

Porous rocks may poison you because microwaves cannot escape from porous material as easily as from non-porous material so they will continue to be absorbed by other food in the area, including the porous rock.

Porous rocks can also explode. Rocks have a certain water content and will heat up as the microwaves go through them, causing this water to vaporize and build up until it cannot be contained any longer and explodes into your food or oven!

The rock could shatter from being exposed to high pressure from being cooked by microwaves, poison you from chemicals leaching out of the rock into whatever you’re cooking, or simply just explode!


Microwaving geodes is dangerous because they are sharp and there is a risk of them exploding so the safest way to open a geode is usually the old-fashioned way – with a hammer and chisel. 

But if you are feeling adventurous and want to try opening your geode in the microwave, just be sure to take the necessary precautions.
