What resin do you use to preserve orchids?

To preserve orchids, epoxy resin is commonly used due to its clarity, durability, and ability to encapsulate the flowers without yellowing over time. Another option is polyurethane resin, which also provides a strong finish but may require more careful handling due to its curing process. Both types of resin allow for a beautiful, glass-like finish that showcases the intricate details of the orchids. It's important to follow safety guidelines while working with these resins, as they can emit harmful fumes.
