Melting crayons in plastic molds is a fun and easy craft that can be done with children. It is a great way to recycle old crayons and teach children about reversible changes. To melt crayons, you can use an oven, microwave, or heat gun. If using an oven, preheat it to between 250 and 350 degrees Fahrenheit. Place the crayons in a mold on a baking sheet and put them in the oven for 7 to 15 minutes, checking regularly to ensure they do not burn. Once the crayons are melted, remove them from the oven and let them cool completely before popping them out of the molds.

Preparing the crayons: Peel wrappers, break into pieces, and sort by colour
Preparing the crayons is the first step in melting crayons in plastic molds. Here is a detailed guide:
Peel the wrappers off the crayons: Removing the paper wrappers from the crayons is necessary before melting them. This can be done by hand or by soaking the crayons in a bowl of water to soften the paper and make it easier to peel. You can also add a drop of dish soap to the water to help loosen the paper. Alternatively, you can use a knife to cut off the paper.
Break the crayons into small pieces: Once the wrappers are removed, break the crayons into small pieces that will fit into your molds. This step is not necessary if you are using broken crayon pieces. However, breaking the crayons into smaller pieces will help them melt faster and more evenly.
Sort the crayon pieces by colour: Sorting the crayon pieces by colour is an important step, especially if you plan to create specific colour combinations or patterns in your moulded crayons. It also adds a fun element of colour sorting and learning for children involved in the activity. You can separate the crayon pieces into different containers or bags based on their colours. This step allows you to experiment with colour mixing and create custom crayon shades.
At this point, you should have peeled, broken, and colour-sorted crayon pieces ready for the next steps of melting and moulding. Remember to supervise young children during the preparation process, as it involves handling small pieces and sharp edges from the crayon wrappers.
Now that you have prepared the crayons, you can move on to the next steps of melting and moulding, which involve placing the crayon pieces into the moulds and applying heat. Enjoy creating your unique and colourful crayons!

Choosing a mould: Silicone is best, but you can use tins, cutters, or containers
Silicone is the best material for moulds when melting crayons. Silicone moulds are oven-safe, freezer-safe, and heat-resistant up to 440–450°F (232–232°C). They are also flexible, which makes it easier to pop out your newly formed crayons.
However, silicone moulds are not your only option. You can use muffin tins, cookie cutters, or small containers. If you are using metal cookie cutters, place them on a lined baking tray and cover them with a cookie tray or glass dish to prevent the wax from spreading. If you are using other types of containers, spray them with cooking spray first to make it easier to remove the crayons once they have cooled and hardened.

Oven method: Preheat oven, place moulds on a tray, and bake for 7-15 minutes
Melting crayons in plastic moulds is a fun activity to do with children. It is also a great way to recycle old crayons. Here is a step-by-step guide to melting crayons using the oven method:
Step 1: Preheat the oven
Preheat your oven to between 250 and 350 degrees Fahrenheit. Different sources suggest different temperatures, but most agree that 275 degrees Fahrenheit is the "sweet spot".
Step 2: Prepare the crayons
Peel the paper wrappers off the crayons and cut or break them into small pieces.
Step 3: Prepare the moulds
Place the moulds on a cookie or baking sheet. Fill the moulds with the crayon pieces. You can fill each mould with different colours or similar shades to create a nice effect. Make sure to overfill the moulds, especially if they are small, as the crayons will melt to fill every empty space.
Step 4: Bake
Place the moulds in the oven and bake for 7 to 15 minutes, or until the crayons have liquefied. Keep an eye on them to ensure they don't overheat or burn. The time will depend on the size of the moulds and the amount of crayon you are melting.
Step 5: Cool
Remove the moulds from the oven and let them cool completely. You can speed up the cooling process by placing the moulds in the fridge or freezer.
Step 6: Remove from moulds
Once the crayons are completely cool, pop them out of the moulds. You can now use your new crayons or gift them to a loved one!

Microwave method: Melt crayons in a cup, then pour into moulds
Melting crayons in plastic moulds is a fun activity to do with kids. Here is a step-by-step guide on how to do it using the microwave method:
Step 1: Prepare the crayons
Remove the paper wrappers from the crayons and divide them by colour. Cut or break the crayons into small pieces. You can use a bowl of water to soak the crayons and make it easier to remove the wrappers.
Step 2: Melt the crayons in a cup
Place the crayon pieces in a microwave-safe cup. You can use paper cups for this, which can be thrown away afterward. Put the cup in the microwave and heat on high for about 4 to 5 minutes. Keep an eye on the crayons as microwaves vary in strength, and the timing depends on the number of crayon pieces you are melting.
Step 3: Pour the melted crayons into moulds
Once the crayons are melted, carefully remove the cup from the microwave. Pour the melted crayons into your moulds. You can use silicone moulds or other non-oven-safe items such as Lego, ice cube trays, or cookie cutters to create fun shapes.
Step 4: Cool the moulds
Place the moulds in the freezer to speed up the cooling process. It should take around 30 minutes for the crayons to harden. Once the moulds are cooled, gently press on the bottom of the mould to pop out your new crayons.
Always be cautious when handling melted crayons as the containers and wax will be extremely hot. Use oven mitts and keep children at a safe distance to prevent burns.

Cooling and removal: Let moulds cool, then pop out the new crayons
Once your crayons are melted and moulded, it's time to let them cool. Place the moulds on a flat surface and let them cool for 20 to 30 minutes. The cooling time depends on the size of your moulds. You can speed up the cooling process by placing the moulds in the fridge or freezer, or even on ice cubes. However, it can be tricky to keep the moulds level and avoid spilling the melted wax when using ice cubes. Be very careful when handling the moulds during this stage, as the hot wax can burn your skin.
To check if the crayons are cool enough, gently press on the moulds. If they feel hard, you can try popping the crayons out. Press on the bottom of the mould from the outside to push the crayon shape out. If your moulds are deeper, you may need to loosen the sides with a knife or another tool before popping out the crayon.
Once your crayons are out of the moulds, they're ready to use! You can also package them in a pretty box to gift to your loved ones.
