With the use of a microwave, you can now dry your flowers very quickly. Flowers should be gathered at their peak or else they will turn brown. Use any of the drying agents (silica gel, sand, borax) in a container deep enough to cover the bloom. Leave a 1/2 inch stem on the flower, and place it face up on a 1/2 inch layer of drying agent. Carefully sprinkle enough agent to cover the flower, and place it in the microwave along with a small bowl of water. Do not remove the flowers from the agent immediately, but set them aside for several hours. Listed below are some times for drying flowers in a microwave.
