Ashland Flower Drying Silica preserves your fresh flowers while maintaining their natural colors and textures to create a beautiful result. Easy to use, flower drying crystals efficiently absorb moisture from flowers, allowing them to dry in less time than air drying, and they’re microwave-safe. Simply cut flower heads apart from stems, cover flowers completely with silica, and allow them to dry for the recommended time. Most flowers dry in 36-48 hours – plus drying crystals are reusable! Create your next dried floral project and enjoy lasting flower vibrancy for your framed pressed flowers, shadow boxes, bouquet arrangements, resin jewelry, and more.
