How to melt plastic bottles

I tell you that they can melt in many ways. One of them is taking a metal container and adding the bottle cut into small pieces. Fill the entire metal container and put it in the oven. If you can get a small stove and take it out of the house, this will prevent the melted plastic from sticking to another surface or the smell of this material melting at home.

You can put the stove at about 120ºC Let everything melt well, inside the metal container. You will see that some gases can escape, when burning more plastic these will be more harmful. Leave the container baking about 4 minutes and then go increasing the heat little by little. You can do it at intervals of 4ºC until you see that it is totally melted.

After the time and well melted, remove the metal container without burning. Then prepare a mold, to shape that plastic. The mold can be any shape you want. After pour the liquid material inside, you can help yourself with a wooden stick. To finish let it cool completely. Then unmold and you will see the figures made.

Last if you have made plastic flowers and you just want to give a little shape to your petals, just use a candle or a lighter and melt the edges a bit. Do not put the heat source too close, but at a safe distance so that it does not burn.

Ideas for plastic molding

Let's see some ideas below to be able to use the melted plastic and turn them into objects for another use.

Mold with reused materials

The first thing we have to do is prepare the original piece that we will use to create the mold. For this, first clean the article well. Once clean, apply a release agent on the original piece to make sure that the original piece will come off.

The next step would be to cover the item with a layer of bubble eliminator to prevent its formation. We will place the original part inside a heat resistant container.

The last step would be pour the melted material on the original piece. Do it carefully and let the product cool so that it hardens. When this happens, it will only be unmold.

Silicone mold

The first will be create a catalyst solution with soap and water. With this mixture, what we are getting is to create a product that makes the silicone harden more quickly. To do this, mix 2 liters of water with 120 milliliters of dishwasher.

Once we have the previous mixture, we must take a bottle of silicone and pour all its contents into the previous catalyst solution. When all the silicone is in the mix, with the help of our hands we will mold it to create a less malleable ball.

To create the mold, we will take the silicone mass and stretch it as if it were a pizza base. We will place the original piece in it by pressing it. Use a product that helps you remove the original part without damaging our mold.

Finally, you must let the mold harden completely. To prevent the silicone from sticking, we recommend adding a little soapy water in a container and inserting the mold into it.

Make the casting of the mold

The first thing will be to prepare the work area. We should look for a place in the house that has good light and ventilation. Cover the area with towels or paper to avoid staining more than necessary.

The next thing we have to do is prepare the mold. It is important to treat it properly to be successful. For example, if the mold is bought, it would have to be washed with hot water to eliminate any residue that may affect us.

We will take plastic resin and mix it well. This resin is formed by two products. You would have to mix both in equal amounts and mix everything well until you get a uniform product.

We will pour the resin inside the mold by spraying the upper part with a release agent to prevent the bubbles from rising upwards.

Finally, remove the item carefully from the mold when the resin has settled. In the case that the mold is silicone, apply pressure on the back with our fingers to remove the item.

What do you think about this idea to recycle plastic bottles? Have you ever melted plastic to decorate?


  1. I eat a lot but when they spill the bottles they smell very unhealthy I say it because I lived very close to a bottle plastic factory and that smell was not very unbearable

  2. You should be able to do everything ... but you should also take cancer flower, because plastic, or rather the gases that last when it burns or melts, is extremely toxic. I would not do it!!!
