Casting rose in epoxy in 7 steps

Casting rose in epoxy explained in 7 steps. In this example we are molding a rose into a cube.

Drying flowers is an art form that has been done for many years. Nowadays there are many easy ways to extend the beauty and life of flowers. One of these is the preservation of flowers in epoxy resin . You can quickly and easily immortalize your wedding bouquet, birthday flowers, funeral flowers or a beautiful rose with epoxy resin.


- Epoxy casting resin
- Silica granules (to dry the flowers) + container to dry the flower
- Cups for mixing, stir sticks, gloves, skewers, clothes peg, scales, scissors and of course the flower of your choice.
- Silicone mold (epoxy mold) of your choice
- Large dried flowers or small dried flowers

Step 1: Drying the flower

You can choose a flower of your choice for your project. In this manual we explain, in a few steps, how you can process a beautiful rose in an epoxy cast resin cube.

In this example we dry a flower with silica granules. There are many other ways to dry a flower, see: drying flowers yourself .

You start by cutting the stem of the flower. You do this 1 cm from the flower. You cut the stem diagonally at a 45 degree angle. This gives the rose a larger opening to drain its moisture. Do not remove damaged leaves before drying. These leaves can protect the beautiful leaves during the drying process.

Pour a soil of about 2 cm with silica granules. Place the flower in it with the stem facing down. Then carefully fill the container with the granules until the flour is covered. When the container is filled, close it and let the flour dry. After a few days the flower will have dried. Carefully pour the granules back into the packaging. You can reuse this for a new project.

Be careful with the flower, it is now very fragile. When you can see the flour, you can remove it from the container. Turn the flour upside down to allow the grains inside to fall out. You can tap the bottom of the flower so that the grains come out properly. Your flower should now be well dried and feel like an autumn leaf. If your flour is not yet completely dry, place it back in the granules. If you start working with a flower that is not completely dried, it will rot in your creation and become very ugly over time. It is normal that the color of the flower has changed slightly due to drying. They usually become slightly darker.
Now you can carefully remove the less attractive or damaged leaves. Drying the flowers can be done in different ways, this is the fastest way and with the best results.

Step 2: Location determination

During this step you will determine where the flower will go in the cube. If you want the flower to 'float' follow these steps. First pour a thin layer of epoxy casting resin into the mold and let it harden. You can then place the flower upside down in the mold. Or you can leave it hanging. You can do this by carefully inserting a skewer into the flower. You then hang this in the cube and hold the flower in place with a peg or 2 ice cream sticks. If you do not do this, it may sink/rise or hang crookedly.

Tape 2 ice cream sticks together at the ends with some adhesive tape. Then insert a skewer into the flower in the flower part. Stop before you reach the stem. After this, place the other end of the skewer in the middle of the 2 popsicle sticks. Then check the outside of the mold to see if the flower hangs well and high enough.

Now the flower is ready to hang in the mold. The popsicle sticks will rest on the sides of your silicone epoxy mold.

Step 3: Mixing the epoxy casting resin

Mix the epoxy casting resin according to the instructions on the back of the bottle. Calculate how much epoxy you need for this mold. If you order from itsOkay.nl , the required epoxy per mold is listed on the product page. Are you going to cast a flower transparently? Always add UV blocker to your epoxy mixture.
For the best result, always cast such a mold 3+ times. If you pour it in one go, there will be too much epoxy in one go and it may become too hot, causing damage to the flower and the mold. You will also experience a lot of air bubbles.

For the 6.5 cm silicone epoxy cube mold we need 250 grams of epoxy. So we are going to pour it in 3 times. Without flour you end up with 3 layers of approximately 83 grams of epoxy (250/3). Because you also have to take the volume of the flour into account, it is best to round this down. Then you end up with 3 layers of 80 grams of epoxy each time. So do not mix more than 80 grams of epoxy at a time. You let it harden for 12 hours per layer and then continue. If you are going to cast a larger mold with epoxy, we recommend not pouring more than 1-2 cm at a time to prevent heat formation. In the meantime, pop the air bubbles with, for example, the Bubble blaster .

Step 4: Pouring the first layer of epoxy

Now you can carefully and slowly pour your epoxy mixture into the mold. Do this on the side of the mold and not on top of the flower to prevent damage to the flower.
A few air bubbles are normal during this process and most will pop during the pouring process. Because the flower is very fragile, it is not advisable to remove bubbles now with a heat tool or alcohol spray. This can damage the flower.

After pouring, cover the silicone cube mold so that dust/hair/insects cannot reach it. Do not seal completely because air must still be able to get in. You will now let your epoxy harden for about 12 hours before pouring the second layer. In a room where it is 20 degrees it will take about 12 hours.

Step 5: Pouring the second layer of epoxy

After 12 hours you have approximately reached the hardness you want for this project. Hard on the outside, but can still be a bit sticky here and there on top. This is good so that the second layer can adhere well to the first layer. The layers then slowly flow into each other and this ensures the least amount of line formation in your creation. Now you can carefully remove the sticks in the flour. Then you will mix the epoxy for the second layer, exactly as you did for the first layer. Mix carefully again and stir for at least 3 minutes. You will slowly pour this layer on top of the flour so that any trapped air in the flour can escape properly. This process will continue so check your project every hour to carefully pop any air bubbles with a toothpick. If you do this regularly you will significantly reduce the chance of air bubbles in your creation. Allow this layer to harden again for about 12 hours, covered but not airtight. You want the same degree of cure as the first coat.

Step 6: Pouring the final layer of epoxy

You pour the last layer of epoxy casting resin in exactly the same way as the previous two layers. Pour the flour on top and now fill the mold completely to the brim. It is best to leave it slightly convex, because the epoxy shrinks slightly. Cover the mold again, but not airtight. This last layer needs to harden for about 48 hours before you can remove it from the mold. Check your creation every now and then to pop any bubbles that may have arisen. If the bubbles are in the flour, try to get them to the surface with a small skewer. Be very careful not to damage the flower. Once on the surface you can easily pop the bubbles.

Step 7: Remove your creation from the mold

After about 48 hours, your mold should be ready to remove from the mold. When you hold the mold it feels rock hard. If you press on it with the blunt side of a stick, it will not leave a print. This way you can be sure that your creation has fully hardened. Carefully remove your creation from the mold, try not to pull too much to avoid tearing the mold.

It is wise to wear gloves as the edges can sometimes be sharp and you can cut yourself. Start at the top of the mold by pushing the outside edges of your creation.

Turn the mold over and press firmly on the bottom. This ensures that the mold releases from your creation and makes it easier to remove your cube from the mold. Your cube with flower is now ready and you have your own epoxy flower. This way you can also store your bridal bouquet in epoxy!
