Drying and Preparing Flowers
Before embedding flowers in resin, it is essential to dry and prepare them properly to maintain their color, shape, and integrity. Fresh flowers contain moisture, which can cause bubbles, discoloration, or mold inside the resin if not fully dried. There are several effective drying methods to consider:
- Air Drying: Hang flowers upside down in a dry, dark, and well-ventilated area for 1–3 weeks. This method preserves shape but may cause slight color fading.
- Pressing: Place flowers between absorbent paper and apply weight or use a flower press. This method is ideal for flat designs and takes about 1–2 weeks.
- Silica Gel Drying: Bury flowers in silica gel crystals inside an airtight container for 2–7 days. This method retains the most vibrant colors and detailed shape.
- Microwave Drying: Use a microwave-safe container with silica gel to dry flowers quickly in a few minutes, but requires careful monitoring to avoid burning.
Once dried, handle flowers gently to avoid damaging delicate petals. Trim stems and leaves to fit your resin mold or project size. If desired, you can apply a thin coat of clear acrylic spray or floral sealant to further protect the flowers and reduce moisture absorption during resin curing.
Mixing and Pouring Resin
The quality and technique of mixing and pouring resin significantly affect the final appearance of flower preserves. Use a clear epoxy or polyester resin designed for casting and coating purposes. Follow these guidelines for best results:
- Measure resin and hardener precisely, usually in a 1:1 or 2:1 ratio, according to manufacturer instructions.
- Stir the mixture slowly and thoroughly for at least 3–5 minutes to ensure even curing and minimize air bubbles.
- Allow the resin to rest for a few minutes after mixing to let bubbles rise to the surface.
- Pour a thin base layer into your mold or frame and allow it to become tacky before placing flowers. This helps prevent flowers from floating or shifting.
- Arrange flowers carefully using tweezers or a toothpick, ensuring the desired orientation and spacing.
- Pour additional resin layers slowly over the flowers to avoid trapping air bubbles.
To reduce bubbles during pouring, consider working in a warm environment and using a heat gun or torch lightly over the resin surface after pouring.
Techniques for Embedding Flowers
Embedding flowers in resin requires patience and precision. Depending on the depth and complexity of your project, you may choose one of the following approaches:
- Single Pour: Place flowers on a base layer and pour resin over them in one go. Best for thin, flat pieces like jewelry or coasters.
- Layered Pouring: Pour resin in multiple thin layers, embedding flowers between each layer. This technique adds depth and prevents flowers from floating.
- Encapsulation: Encase flowers inside resin molds, ensuring the entire flower is fully submerged and suspended in resin.
Proper positioning is crucial. Use tools such as:
- Tweezers for delicate placement.
- Silicone molds to hold resin and flowers in shape.
- Toothpicks or needles to gently reposition petals or remove bubbles trapped near the flowers.
Curing and Finishing
Curing times vary depending on resin type, temperature, and layer thickness. Typically, epoxy resin cures within 24–72 hours at room temperature. To achieve a smooth, glossy finish:
- Cover your project to protect it from dust during curing.
- Avoid moving or disturbing the resin while it hardens.
- Use a heat gun or small torch to eliminate surface bubbles just after pouring.
After curing, you may need to sand and polish the resin surface to remove imperfections or uneven edges. Use progressively finer grit sandpaper (starting around 400 grit and moving up to 2000 grit) and finish with a polishing compound for a clear, glass-like shine.

Selecting and Preparing Flowers for Resin Preservation
Choosing the right flowers and preparing them properly is critical to achieving a beautiful and long-lasting resin preservation. Fresh flowers contain moisture that can cause cloudiness or discoloration in resin, so drying is a necessary step.
Flower Selection Tips:
- Choose flowers with minimal moisture content and sturdy petals, such as roses, pansies, or hydrangeas.
- Avoid flowers that wilt quickly or have delicate petals that may crumble during handling.
- Smaller flowers or individual petals often work better for embedding in resin due to easier positioning and less air trapping.
Drying Methods for Flowers:
| Drying Method | Description | Advantages | Disadvantages |
|---|---|---|---|
| Air Drying | Hang flowers upside down in a dry, dark, and ventilated space for 1-3 weeks. | Simple, no special equipment needed, preserves shape well. | Time-consuming, colors may fade. |
| Pressing | Place flowers between absorbent paper under weight or in a flower press. | Flattens flowers for thin resin projects, retains color better. | Flowers become fragile and two-dimensional. |
| Silica Gel Drying | Bury flowers in silica gel crystals for 3-7 days to draw out moisture. | Preserves shape and vibrant color, faster than air drying. | Cost of silica gel, requires careful handling. |
| Microwave Drying | Use a microwave-safe container with silica gel for rapid drying. | Quickest method, good color retention. | Risk of overheating and damaging flowers. |
After drying, handle flowers with tweezers or gloves to avoid oils and moisture from hands transferring onto the petals.
Preparing Resin and Embedding Flowers
Proper resin preparation and embedding technique ensure clarity and durability of the preserved flowers.
Choosing the Right Resin:
