Are you looking to add a unique and eye-catching piece of art to your home? If so, you must try your hand at creating free-form resin geode artwork. With their vibrant colours and organic shapes, resin geodes will add a touch of whimsy and elegance to your space. This blog will guide you through creating your resin geode artwork, from the needed materials to the step-by-step instructions. You can easily join a resin art course to learn this technique more thoroughly and under professional guidance. So, let's dive in and get started on this exciting and creative project!

What Is Resin Geodes Artwork?

Resin geode artwork is a captivating and unique artistic expression that combines geodes' beauty with resin's versatility. It involves creating stunning decorative pieces that mimic geodes' natural beauty and intricacy using resin as the primary substance. Resin geode artwork has gained popularity recently for its ability to create mesmerising pieces that resemble the equally mesmerising crystalline structures in natural geodes.

Materials and Supplies for Creating Free-Form Resin Geodes Artwork

Before you begin your resin geode artwork, gathering all the necessary materials and supplies is important. Here's a list of what you'll need:

  • Epoxy Resin: Choose a high-quality epoxy resin for arts and crafts projects. Make sure to follow the manufacturer's instructions for mixing and pouring.
  • Resin Dyes or Pigments: These will add vibrant colours to your geodes. Opt for translucent or transparent dyes for a more realistic effect.
  • Geode Moulds: Look for silicone moulds in various shapes and sizes to create the organic shape of geodes. You can find these moulds online or at your local craft store.
  • Mixing Cups and Stir Sticks: Use disposable cups and stir sticks for mixing the resin and dyes.
  • Protective Equipment: Wear gloves, a mask, and protective eyewear to ensure your safety while working with resin.
  • Additional Materials: You may also need glitter, crushed glass, or other embellishments to add texture and sparkle to your geodes.

Steps to Create Free-Form Resin Geodes Artwork

Now that you have your materials ready, let's move on to the step-by-step instructions for creating your own free-form resin geode artwork:

Prepare Your Work Area

Cover your work surface with a plastic sheet or old newspapers to protect it from spills or drips. A transparent vinyl shower curtain is recommended. This vinyl curtain will be used as the substrate for your geode art. Secure it to the hardboard using packaging tape, leaving one edge free for later removal.

Mix the Epoxy Resin

Following the instructions on the packaging, measure the correct ratio of resin and hardener into a mixing cup. Stir the mixture thoroughly for the specified time to ensure proper curing. Once your resin is ready, separate it into individual paper cups based on the number of colours you've chosen for your geode. This will allow you to mix in the coloured pigments easily.

Add Resin Dyes or Pigments

Once your resin mixture is well mixed, it's time to add colours. Mix tinted resin using 2-3 shades of white and 1-2 pops of colour, complementing the first layer. Pour a thin line of tinted resin against the top edges of the crystals and the panel to cover any imperfections. Mix well until the colours are evenly distributed.

Pour and Manipulate the Resin

Working from the outside in, layering each resin colour until you've reached the centre, alternating colours and opacities. You heat the resin with a heat gun or torch to remove bubbles. The idea of layer two is to fix anything you dislike. So, only apply transparent tints to the areas you already love. However, using coloured resin for the second layer is recommended to enhance your geodes' colour intensity and depth.

Add Embellishments

If desired, sprinkle glitter, crushed glass, or other embellishments onto the wet resin to add texture and sparkle. You can experiment with different combinations to create unique effects. Additionally, consider adding geode lines to enhance the appearance. Mix gold Mica Powder with resin to create thin lines using a syringe or a gold marker pen.

Let the Resin Cure

Follow the manufacturer's instructions and let the resin cure, which can take from 24 to 48 hours, based on the epoxy resin brand. Once dry, gently warm the resin drips using a heat torch, making it easier to remove the tape. Remember to wear gloves and remove the tape slowly to avoid any accidents. If any drips remain, sand them down once completely dry to achieve a smooth and professional finish.

Finishing touches: If desired, you can sand the edges of your geodes to give them a polished finish. You can also apply a clear coat of resin to enhance the shine and durability.

Tips for Making Free-Form Resin Geodes Artwork

  • Before starting, ensure that your workspace is well-ventilated, and remember to use safety equipment like respirator gloves and tie your hair back. Maintain a temperature of 21-24C or 70-75F for proper curing.
  • Mix resin and hardener for 4 minutes, then add a small amount of mica powder to create desired colours.
  • Remember to protect your workspace properly, prep the base, choose complementary colours, experiment with crystals, add geode lines, and finish the project.
  • If you wish to have glitter layers, create a small batch of clear resin and sprinkle with glitter once the resin has been poured. Add this layer on top for a sparkling effect.


Before you get started, gather all the necessary materials and supplies, including high-quality epoxy resin, resin dyes or pigments, geode moulds, mixing cups and stir sticks, and protective equipment. Once everything is ready, follow the step-by-step instructions to create your resin geodes artwork. Remember to prepare your work area, mix the epoxy resin, add resin dyes or pigments, pour the resin, and add embellishments. After allowing the resin to cure, add finishing touches, such as sanding the edges and applying a clear coat. Remember some helpful tips, such as ensuring proper ventilation, maintaining the right temperature, protecting your workspace, etc. To learn more about resin art and its various techniques, visit Arts Shala's website.
