Preserving flowers in resin isnโt just an art โ itโs a science.
Turning fresh flowers into timeless resin pieces is a rewarding craft that captures special memoriesโlike wedding bouquets, anniversary gifts, or garden favorites. But success depends on understanding the science: moisture control, proper curing, and careful layering. Skip steps, and you risk bubbles, yellowing, or even mold inside your creation. Follow this guide for professional-looking results every time. ๐
Step 1: Thoroughly Dry Your Flowers โ The Critical First Step ๐
Fresh flowers hold a lot of water, which can cause cloudiness, discoloration, or decay when sealed in resin. Proper drying is essential.
The most effective home method uses silica gel desiccant to gently remove moisture while preserving shape and color.
Supplies needed: Fresh flowers (roses, hydrangeas, baby's breath, etc.), airtight container, and Wisedry silica gel.

Step 2: Prepare Your Workspace and Materials ๐ ๏ธ
Work in a well-ventilated area. Wear gloves, and protect surfaces.
Key supplies: Clear epoxy resin and hardener (choose UV-resistant for longevity), silicone mold, mixing cups, stir sticks, heat gun/torch or vacuum chamber for bubbles, and your dried flowers.
Ensure everything is dust-free and level.

Step 3: Fix Flowers with the First Resin Layer ๐
Arrange your dried flowers in the mold as desired.
Mix resin and hardener according to the manufacturer's exact ratio.
Stir thoroughly for several minutes to ensure complete mixingโpoor mixing leads to sticky spots or incomplete cure.
Pour a thin initial layer into the mold (enough to cover the bottom).
Gently place and position your flowers on this layer. It anchors them in place and helps isolate them from air, reducing bubbles later.
This base layer must fully cure before adding more resinโcheck your product's instructions (typically 24โ48 hours for full hardness; test with a toothpickโit should feel rock-solid with no tackiness).

Why Layering Is Essential โ The Science of Curing โ ๏ธ
Epoxy resin cures through an exothermic reactionโit generates heat as it hardens. Pouring everything at once can cause excessive heat buildup, which may scorch delicate dried flowers, cause yellowing/browning, or create large bubbles and uneven curing.
Always pour in thin layers and wait for full cure between each pour. This controls heat, prevents damage, and gives clearer, more professional results. Patience is key!

Step 4: Build Layers Gradually Until Fully Encased ๐จ
Mix a new batch of resin (stir well again).
Pour the next layer slowly over the cured piece.
De-bubble immediately: Bubbles are normal after mixingโuse a heat gun/torch to pop surface bubbles, or better yet, place in a vacuum chamber if you have one for professional clarity.
Wait for full cure (again, follow your resin's timelineโoften 24+ hours per layer).
Repeat: mix, pour, de-bubble, fully cureโuntil flowers are completely covered and the piece reaches desired thickness.
Final full cure: Let sit undisturbed for 48โ72 hours (or as specified) in a warm, dust-free area.
Demold gently, sand rough edges if needed, and polish for a glossy finish.

Quick Tips for Success & Common Pitfalls ๐ซ
- Always follow your specific resin's instructionsโcure times and mixing ratios vary.
- Work in low-humidity conditions to avoid clouding.
- For extra protection, consider a light UV spray on dried flowers before resin.
- Start small (e.g., pendants or coasters) if you're new.
- Bubbles? Don't skip de-bubblingโit's the difference between amateur and pro.
Preserving flowers in resin creates heirloom-quality pieces that keep memories alive forever. With proper drying (at least a week with desiccant) and careful layering, you'll get stunning, bubble-free results. Ready to start?
