Which technique preserves evergreen and deciduous foliage and some flowers by treating with glycerin?

• A. Glycerin treatment
• B. Air-drying
• C. Pressing
• D. Desiccant drying

Answer: (A)

Glycerin treatment preserves foliage by replacing the water in plant tissues with glycerin, so leaves and stems stay flexible and retain a natural color. The material is soaked in a glycerin-and-water solution, allowing glycerin to diffuse into the tissues and gradually take the place of moisture. This substitution prevents the brittleness and color fade that happen with drying, keeping evergreen and deciduous foliage looking green and pliable for a longer time, and it can also help some flowers retain a softer, more life-like texture. Compared with air-drying, pressing, or desiccant drying, glycerin treatment yields a more lifelike, resilient result that holds shape better for use in arrangements.
