This way of drying flowers preserves their three-dimensional shape.
To use, cover the flowers and foliage with the dry silica gel crystals, being careful to support leaves and petals as you go. After several days the crystals will absorb the moisture from the plant, leaving you with completely dry flowers. You can use the silica gel conventionally in a sealed container, or speed up the process by putting it in an oven (where it takes only a few hours to dry the material) or microwave oven (where it takes only a few minutes).
The crystals are reusable indefinitely; to recharge, dry them in an oven for about 30 minutes. Mixed in with the colorless crystals are indicator crystals that change color as they absorb moisture to indicate when recharging is required.
Contains 2kg (4.4 lb) of pure silica gel crystals.
