What is a Geode?

 

Natural Geodes

The term “geode” (Greek: γεώδης, geōdēs for earthy) comes from geology or mineralogy and describes a round hollow space in rock, which is occupied by geological processes with minerals and crystals. Geodes are mostly formed in volcanic lava rocks which, after cooling, contain gas bubbles. When hot water with dissolved quartz penetrates these cavities, the crystals can grow and depending on the added trace elements, take on the different colours of the smoky quartz or the amethyst. Geodes can also contain other types of minerals, e.g. amethyst, quartz, agate and jade. Finding geodes is not easy, most of the time they are spherical or almond shaped stones and can hardly be distinguished from the surrounding rocks. They only reveal their sparkling inner life after impacting or in cross-section.

Resin Geode Wall Art

Inspired by the natural geodes, you can now create beautiful geodes with resin, deco stones, glitter and of course real crystals and minerals. There are no limits to your imagination and the “geode imitations” made of resin look with a little practice deceptively similar to the real minerals from nature. Of course you can also cast resin geode wall art on a suitable painting ground or, as in our case, as a free form. Such free form geodes can also be processed wonderfully e.g. to tables etc. or you can use them as fancy coasters.

Step by Step Tutorial for Free Form Resin Geodes

 

Surface Assembly

Before you can start casting your geodes in Free Form Style, you must first prepare a suitable substrate. We recommend a transparent vinyl shower curtain, which we apply to a hard board surface.

  • Take your clear vinyl shower curtain and cut a section slightly larger than your hard board surface. Secure it to your hard board with packaging tape (this will be removed on one edge at a later point). Remember, the vinyl may have creases and wrinkles but that’s okay.
  • Now draw your desired geode shape with a marker using the reference photo.
  • Following your drawn form, place a line of silicone sealant around your geode with the help of a caulking gun. Wait about 5 minutes and add another layer of silicone on top of the first one. If you want your geode to have a cavity in the center, you can apply a boundary with silicone in the middle (same shape as the geode, only in small size). In our example the geode is closed in the center.
  • Wait another 5 minutes and moisten a gloved finger with dish soap. Now, smooth out the inside surface of the silicone with with your soapy finger. This is therefore necessary so that your geode later has as even an edge as possible without sharp edges.
  • Two layers should be enough depending upon your project. If you’re preparing your mold for a large piece like resin geode tables, you may need several layers. So that the geode has the necessary thickness or stability. Your mold will be ready for use in approximately 45 minutes.

Resin Prep

Prepare your resin according to the packaging directions. We prefer Stone Coat Countertops Resin, 1 part epoxy to 1 part hardener. Now, separate your resin into individual paper cups according to the number of colors you have chosen for your geode and mix in the colored pigments. We prefer using various brands of pigment pastes and pigment powders. Also, added glitter or mica flakes to your resin is another way to add some interest and texture to your geode.

 

 

Pouring Your Free Form Geode

One of the most important tips we can give you is to make sure your surface is level. So, using your leveling tool, check every angle including diagonally. You can shimmy the board with your stir sticks if you need to. Now you’re ready for the fun part.

  • Working from the outside in, start layering each color of resin until you’ve reached the center alternating colors and opacities.

  • All the while heating the resin with heat gun or butane torch to encourage the release of any bubbles. Be careful not to heat your resin too much as this will cause the plastic to warp and mess up your work.

  • Layer one is only the preliminary version so don’t worry if it isn’t perfect, you won’t see any imperfections after layer two.
  • Now that your center point is established you can add mirror glass pebbles, mica flakes, deco stones, or crystals.
  • Layer one is complete and needs to cure prior to layer two. (depending on brand and type of resin, it takes between 4 and 24 hours to cure). The idea of layer two is to fix anything you dislike.

  • So, only apply transparent tints to the areas you already love. If you are satisfied with layer one, then simply add a clear layer. However, we recommend that you also use coloured resin for the second layer, as this will further enhance the colour intensity and depth of your geodes.
  • Depending on your taste, you can now also add further 3D elements such as mirror glass pebbles, decorative stones or crystals.
  • For an easy way to store your art in a dust-free zone, turn a storage container upside down and place it over your art. WaLaa – you are now a geode artist!

Unmolding

To allow your geode to set up completely, we recommend waiting for 24 hours. Once your resin is set, remove one of the edges of tape so you are able to place a hand behind the vinyl. Now, gently pry away the silicone from your geode careful not to pull the silicone from the vinyl. Press against the silicone border if you need to while following along the edges of the geode on all sides until it’s free. The edges of your geode may be sharp so be careful not to cut yourself. Sharp edges can be sanded off with a sandpaper, if necessary, as soon as the geode has been fully stocked. Optionally you can add accents to your finished geode with a special marker pen.

The mold can be reused over and over as long as the silicone is still adhered to the vinyl. If a section has become loosened, simply cut this portion out and reapply the silicone caulking to this area.
