Prepare mushrooms: Clean, dry, and coat mushrooms with a preservative to prevent decay in resin
To prepare mushrooms for suspension in resin, the first step is to clean them thoroughly. Gently brush off any dirt or debris using a soft-bristled brush or a clean, dry paintbrush. Avoid using water, as moisture can accelerate decay. If the mushrooms have stubborn particles, lightly wipe them with a slightly damp cloth, ensuring no water is absorbed into the mushroom itself. The goal is to remove surface contaminants without compromising the mushroom’s structure or introducing moisture.
After cleaning, drying the mushrooms is crucial to prevent mold or decay when encased in resin. Place the mushrooms in a well-ventilated area, away from direct sunlight, and allow them to air-dry completely. This process can take several days, depending on the size and moisture content of the mushrooms. For faster results, use a food dehydrator set at a low temperature (around 40-50°C or 104-122°F) to remove all moisture. Ensure the mushrooms are crisp and lightweight before proceeding, as any residual moisture can cause bubbling or cloudiness in the resin.
Once the mushrooms are fully dried, coating them with a preservative is essential to prevent decay and ensure longevity in the resin. A common preservative is a mixture of clear acrylic spray or varnish, which creates a protective barrier. Lightly spray or brush the preservative onto the mushrooms, ensuring an even coat on all surfaces. Allow the first layer to dry completely before applying a second coat for added protection. This step is vital, as it seals the mushrooms and prevents them from absorbing moisture or degrading over time.
Another effective preservative option is diluted wood hardener, which penetrates the mushroom’s structure to strengthen and preserve it. Mix the wood hardener according to the manufacturer’s instructions and carefully brush it onto the mushrooms. Allow the hardener to soak in for the recommended time, then wipe off any excess. This treatment not only preserves the mushrooms but also enhances their durability, making them ideal for resin suspension.
Finally, inspect the mushrooms after cleaning, drying, and coating to ensure they are ready for resin suspension. Check for any signs of moisture, uneven coating, or damage. If everything looks satisfactory, the mushrooms are now prepared to be embedded in resin. Proper preparation at this stage is key to creating a clear, long-lasting resin piece that showcases the mushrooms beautifully without decay or discoloration.

Mixing resin: Follow precise ratios and mixing techniques to avoid bubbles and imperfections
When mixing resin for suspending mushrooms, precision is key to achieving a clear, bubble-free finish. Start by carefully measuring the resin and hardener according to the manufacturer’s recommended ratio, typically by volume or weight. Use digital scales or measuring cups specifically designed for resin work to ensure accuracy. Even a slight deviation in the ratio can lead to improper curing, cloudiness, or stickiness. Always mix in a well-ventilated area and wear protective gear, such as gloves and a mask, to avoid skin contact and inhalation of fumes.
Once measured, pour the resin and hardener into a mixing cup, preferably silicone or plastic, to prevent sticking. Stir slowly and deliberately using a silicone spatula or wooden stick, ensuring you scrape the sides and bottom of the cup to fully combine the components. Avoid stirring too quickly or aggressively, as this introduces air bubbles. Aim for a slow, consistent motion for at least 3–5 minutes to ensure thorough mixing. Incomplete mixing can result in uncured spots or uneven clarity in the final piece.
To minimize bubbles, work in a room with minimal dust and airflow, as particles and drafts can disrupt the resin surface. After mixing, let the resin sit for a minute to allow larger bubbles to rise to the surface. You can then use a heat gun or kitchen torch on a low setting to gently sweep over the surface, popping any remaining bubbles. Be cautious not to overheat the resin, as this can cause discoloration or warping. Alternatively, tapping the mixing cup gently on your work surface can help dislodge bubbles before pouring.
When suspending mushrooms in resin, ensure they are completely dry and free of moisture, as water can cause bubbles or cloudiness. Place the mushrooms in the mold first, then slowly pour the mixed resin in a thin, steady stream to avoid disturbing their placement. Pouring too quickly or from a high height can trap air and create imperfections. Use a toothpick or skewer to adjust the mushrooms’ position if needed, being careful not to introduce new bubbles.
Finally, after pouring, cover the mold with a dome or lid to protect it from dust and debris while curing. Allow the resin to cure fully according to the manufacturer’s instructions, typically 24–72 hours, depending on the product. Rushing the curing process can lead to tackiness or softness.

Curing process: Allow resin to cure in a dust-free, stable environment for best results
The curing process is a critical step in suspending mushrooms in resin, as it ensures the final piece is clear, durable, and free from imperfections. To achieve the best results, it is essential to allow the resin to cure in a dust-free, stable environment. Dust particles can settle on the surface of the resin during curing, causing blemishes or cloudiness, while fluctuations in temperature or humidity can lead to uneven curing or bubbles. Begin by selecting a workspace that is clean, well-ventilated, and away from drafts or airborne particles. Covering the resin piece with a protective dome or placing it in a sealed container can further minimize dust contamination.
A stable environment is equally important for proper curing. Resin requires consistent temperature and humidity levels to harden correctly. Ideal curing temperatures typically range between 70°F and 75°F (21°C to 24°C). Avoid placing the resin near heat sources, direct sunlight, or air conditioning vents, as these can cause temperature fluctuations that may lead to cracking, warping, or incomplete curing. If your workspace is prone to temperature variations, consider using a curing tent or a small enclosure with a thermometer to monitor and maintain optimal conditions. Humidity should also be moderate; excessive moisture can prolong curing time or cause a tacky surface.
The curing time for resin varies depending on the product used, but it generally takes 24 to 72 hours for the resin to fully harden. During this period, it is crucial to leave the piece undisturbed. Moving or handling the resin too soon can introduce air bubbles, shift the suspended mushrooms, or disrupt the surface. Patience is key; resist the urge to touch or test the resin's hardness until the recommended curing time has elapsed. If you're using a resin with a longer curing time, plan accordingly and ensure the environment remains stable throughout the process.
To enhance the curing process, some artisans use UV light to accelerate hardening, especially for UV-resin products. If you opt for this method, ensure the UV light source is positioned at an appropriate distance and angle to evenly cure the resin without overheating it. However, not all resins are UV-compatible, so always check the manufacturer's instructions before applying this technique. Regardless of the resin type, maintaining a dust-free and stable environment remains the cornerstone of a successful cure.
Finally, once the resin has fully cured, inspect the piece for any imperfections. If dust particles or bubbles are present, they can often be sanded or polished out, but prevention is always better than correction. By prioritizing a clean, stable curing environment from the start, you'll ensure that your suspended mushroom creation retains its clarity, beauty, and structural integrity. This attention to detail will elevate your resin art and make the curing process a seamless part of your crafting journey.
