How to Melt Glue Sticks in The Microwave

There are different ways to melt glue sticks, but one of the most popular methods is to use a microwave. Whether or not it’s a good idea to use a microwave is up for debate. Some people say that it’s not safe to microwave glue sticks, while others say it is.

One thing that’s for sure is that microwaving glue sticks can be messy. The melted glue can splatter and cause a mess in your microwave. It can also be dangerous if you’re not careful.

There are many reasons why you might need to melt a glue stick. Perhaps you’re a crafter, and you need the glue so that you can use it in a project, or maybe your kids want to make something with the leftover pieces of their old toys?

Whatever your reason, here are the step-by-step instructions on how to melt glue in the microwave.

1. Remove The Glue Sticks

The first step in microwaving any glue stick is to remove the glue stick from its packaging. As mentioned early, there are two types of glue sticks that you can safely microwave: hot glue gun sticks and regular all-purpose glue sticks.

To remove all-purpose or school glue sticks from their original packaging, you’ll need to pull or break off the glue stick from its plastic casing. If your glue stick has a plastic piece through the center, you’ll need to carefully cut it away using a knife.

Hot glue gun stick is simpler. All you need to do is remove it from any wrapping or wrapper.

2. Place The Removed Glue Sticks into a Microwave Safe Container

You’ll need to have a microwave-safe container before you can continue with the next step. It doesn’t matter if it’s ceramic or glass, but make sure it’s microwave-safe.

You can use a single-use paper bowl or a ceramic or glass mug to house the glue sticks. If you’re planning to use the same bowl or mug for your crafting project, feel free to use it.

However, if you just need to melt the glue sticks occasionally, then a single paper bowl that you can dispose of when you’re done with it may be a better option.

3. Microwave On Full Power in Short Intervals

Next, place the container in your microwave and turn it on. Set the power to the highest setting, and be sure to keep a close eye on your glue sticks.

Ideally, you shouldn’t need more than twenty seconds in the microwave. Stir it with a plastic spoon after microwaving it.

The glue should already be somewhat melted, but if it’s not, then you can microwave for another twenty seconds until you notice that your glue is completely melted and there are no more clumps or chunks left.

4. Remove The Glue and Use It Right Away

Finally, carefully and slowly remove the container from your microwave and use it immediately. If the glue re-hardens again after some time, then simply re-heat it in your microwave for another twenty seconds to melt it again.

Safety Precautions When Microwaving Hot Glue Sticks

Just like with any other activity, there are some safety precautions that you need to keep in mind when microwaving hot glue sticks. Here are some of them:

  • Inspect the glue stick and make sure there are no plastics or wrappings inside or around the stick. If there is, remove them all before microwaving.
  • Be sure to put the glue stick fully inside the container to avoid the glue melting out.
  • If this is the first time you are using a particular hot glue stick, use smaller amounts to test how long it takes to melt.
  • Never leave your microwave unattended. Always supervise it at all times while you melt the hot glue.
  • Don’t overheat it. The glue can release fumes and smoke if heated for too long, which isn’t good to inhale.
  • Make sure to have a potholder or oven mitt to avoid getting burned.
  • Do not touch the melted glue with your hands since hot glue adheres to the skin easily and causes injury and burns in the process.
  • Do not inhale the fumes as some glues may contain toxic chemicals.


So, can you microwave hot glue sticks? The answer is: yes, you can! Just remember to follow the instructions and safety precautions outlined above, and you’ll be good to go.
