Desiccant: a substance that absorbs moisture; e.g., sand, alum, borax, cornmeal, and silica gel; often used to dry flowers and foliage. Silica gel: a highly absorbent, amorphous
form of silica that resembles white sand, used chiefly as a dehydrating agent for drying fresh plant materials Preserved Botanicals
Freeze drying: a process of drying plant materials. Materials are first frozen, then ice crystals are slowly removed from the plant cells through a vacuum system within a freeze-drying unit. Most flowers
retain shape, suppleness, texture and color. Freeze-dried Rose petals
Freeze-dried dendrobium orchid Air drying: a method of drying fresh flowers and foliage by leaving them out of water in the open air and allowing
moisture of dissipate, often accomplished by hanging the plant material upsidedown. Preserved Botanicals Rack drying: a method of drying fresh
materials by laying the plant material on an elevated, flat surface or screen to allow free movement of air, permitting moisture in the material to dissipate Hanging: a method of air drying by
hanging plant materials upside-down so as to prevent flower heads from drooping, thereby retaining their natural position. Air dried cockscomb
Air dried sunflowers Preserved green roses
Air Dried flowers Air-dried wreath Air-dried lavender
Parchment paper roses Hand-made paper roses
Flowers made out of Sola wood Preserved Botanicals Kiln drying: a method of removing moisture from plant materials by placing
the plant or flower structures into a low temperature (100 degree) conventional oven. Microwave drying: a preservation method whereby plant materials are placed in
silica gel and heated in a microwave oven to quickly remove moisture from the plant material. Preserved Botanicals
Pressing: a method of drying plant materials between absorbent sheets of paper upon which weight or pressure is applied, resulting in flattened specimens.
Potpourri: a mixture of dried and preserved petals, herbs, and other materials, either naturally fragrant or blended with oils or spices, used to perfume rooms and personal items.
Potpourri Preserved Botanicals Acrylic water: a product composed of two
liquids which, when mixed together, gradually harden into a transparent solid that resembles clear water. Acrylic water is often used in glass vase arrangement of artificial flowers to create the appearance of fresh flowers arranged in
water. Acrylic water Preserved Botanicals
Moss: a small, primitive, spore-bearing plant found growing in damp areas on soil, bark, rocks, etc. Sheet & Spanish Moss
