The process is simple yet addictive, allowing even beginners to experiment with this art form while producing stunning, one-of-a-kind pieces. Ready to dive in? Let’s explore how you can create your DIY resin petri dish masterpiece!
Resin petri dishes are named after the petri dishes used in science labs for cultivating bacteria or fungi. In this artistic twist, instead of growing cultures, artists use resin to capture swirling clouds of color that resemble abstract galaxies, cosmic phenomena, or even intricate microscopic worlds. These pieces have an organic, unpredictable quality, giving each creation its personality. How the alcohol ink interacts with the resin often mimics natural processes, such as blooming flowers or ink dispersing in water. The visual effects achieved are usually mesmerizing, making resin petri dishes a standout addition to any art collection or home décor setup.
Creating your resin petri dish offers you creative control over every aspect of the project. You decide the color scheme, the type of ink, and even the mood of the final piece. Whether you want something bold and dramatic or subtle and soothing, DIY allows you to experiment without limitations. Beyond the artistic appeal, resin petri dishes make fantastic personalized gifts. Handmade gifts tend to carry a lot more meaning, and recipients often cherish the fact that they were made with care and creativity. Also, mastering this technique opens the door to resin-related projects like jewelry, coasters, or furniture accents.
Before you embark on your resin petri dish-making journey, you must ensure you have all the right tools and materials. Using high-quality epoxy resin will make a difference in your final product. Not all resins are created equal, and cheaper varieties may result in yellowing or cloudiness over time. Petri dish molds, designed explicitly for resin art, are the next essential item. Silicone molds work best because they are flexible, making it easy to pop your resin creation out once fully cured. You can also get creative with inks—alcohol inks work wonders for the petri dish effect, offering vibrant and fluid patterns when mixed with resin. Don’t forget the basics, like gloves, protective gear, and proper ventilation, as working with resin can be hazardous without appropriate precautions.
Here’s a list of the items you’ll need to create your DIY resin petri dish:

Making your resin petri dish is relatively straightforward but offers plenty of room for artistic interpretation. It begins with setting up a clean, well-organized workspace. This is especially important because the resin can be unforgiving if it spills or gets on surfaces you don’t intend to work with. Follow that by carefully mixing your resin according to the package instructions. Most epoxy resins require precise ratios, so measuring accurately is essential. Once you’ve mixed the resin and hardener, it’s time to pour it into your petri dish mold. The magic happens when you add alcohol inks, watching them bloom into intricate designs as they interact with the resin. It’s a process that combines both creativity and patience, as the resin needs time to cure after the inks have been added.
Prepare Your Workspace
Preparation is the key to success in resin art. Since resin can easily stain or ruin surfaces, covering your workspace with plastic sheeting or a silicone mat is essential. It’s also a good idea to keep some baby wipes or paper towels nearby in case of spills. Proper lighting will help you see any bubbles or imperfections as you work. Make sure your area is free from dust, as any particles that settle into the resin can be complex to remove and can ruin the smooth, glossy surface. This step might seem minor, but ensuring a clean, polished final product is crucial. Don’t forget that resin can release fumes, so make sure your workspace is well-ventilated, or wear a mask if necessary.
Mix the Resin
Mixing the resin and hardener is critical, and attention to detail is vital.
Measure the resin and hardener based on the recommended ratio provided on the packaging, typically either 1:1 or 2:1, depending on the specific brand you’re using. If these proportions are off, the resin may not cure properly, leading to a sticky or soft end product. Slowly and carefully stir the mixture for about 3 to 5 minutes, scraping the sides and the bottom of the container to achieve a smooth, even blend. A common mistake is to stir too quickly, which can introduce bubbles into the resin. Bubbles can be difficult to remove later, so preventing them from forming during this step is better.
Pour the Resin into the Mold
Pouring the resin into your mold might seem like a straightforward task, but this is where precision is critical. Pour slowly and steadily to avoid introducing bubbles. Depending on the depth of your mold, you may want to pour in layers, allowing some time between each pour to prevent excessive air entrapment. If you plan to add more intricate design elements or embellishments later, be mindful of how much resin you initially pour. Filling the mold to the top can make adding layers of ink or additional effects difficult without risking overflow. Slow, deliberate actions are the best approach during this step to ensure an even, smooth surface for your inks to bloom.
Add Alcohol Inks
Now for the fun part: adding your alcohol inks. You can use several techniques, depending on the effect you want to achieve. Dropping the ink directly into the resin will result in blooming, cloud-like patterns while swirling the colors together, which can produce marbled effects. If you’re looking for more defined patterns, use a toothpick or skewer to guide the ink as it spreads. How alcohol inks behave in the resin can be unpredictable, which is part of the magic. Each drop of ink reacts with the resin differently, sometimes sinking to create 3D effects while other times spreading out in delicate wisps of color.
Pop Air Bubbles
Air bubbles are one of the most common issues encountered in resin art. Fortunately, they can be quickly addressed with the right tools. After adding your inks, gently pass a heat gun or small torch over the surface of the resin. This will help to release any trapped air, ensuring a crystal-clear finish. Take care not to overheat the resin, as doing so may result in it curing too rapidly, which could cause warping or create uneven surfaces. For smaller projects like a petri dish, a lighter touch is often all that’s needed. Another tip is to gently tap the sides of your mold to encourage any remaining bubbles to rise to the surface.
Let It Cure
Resin curing is a process that requires patience. Once you’ve finished your design, the resin must sit undisturbed for at least 24 hours—longer for thicker pours.
Avoid the temptation to touch or shift your project while it’s curing, as even a minor disruption can result in fingerprints or small dents on the surface. Some artists cover their pieces with a plastic container or box to prevent dust from settling onto the resin during curing. While waiting can be difficult, rushing the process will likely result in a flawed final product. Trust the process, and you’ll be rewarded with a beautifully cured, glass-like surface.
Demold and Finish
Finally, the moment you’ve been waiting for—demolding your resin petri dish. Slowly and carefully peel the silicone mold away from the resin, careful not to bend or crack the piece. If you notice any rough edges, sand them down with fine-grit sandpaper. For those who prefer a glossy, high-shine finish, consider applying a clear resin topcoat or buffing the surface with a polishing compound. Adding these final touches can elevate your piece from a simple craft project to a professional-grade art piece. With the proper care, your resin petri dish can become a long-lasting piece of décor or a cherished gift for someone special.
Experimentation is the heart of resin art. Each pour can produce entirely different results, and the more you play with the medium, the more you’ll discover its endless possibilities. Using different alcohol ink brands can yield varying effects, as some may bloom more dramatically while others might offer more subtle diffusion. Don’t hesitate to experiment with glitter, mica powders, or even small trinkets embedded into the resin. These additions can give your petri dish an extra layer of depth and visual interest. Another critical factor is color choice. Understanding how colors interact can help you develop visually appealing designs.
Even seasoned resin artists run into problems now and then. If you encounter air bubbles that won’t go away, warming your resin slightly before pouring can help. Sticky or soft resin usually indicates a mixing issue—either the resin and hardener were not measured correctly or stirred long enough. Cloudiness can result from moisture or improper mixing, so always work in a dry environment and follow the manufacturer’s instructions closely. Mistakes happen, but with practice, you’ll learn how to troubleshoot these issues and create flawless pieces every time.
