Silica Gel For Drying Flowers

Flowers are one of nature’s most stunning creations. It is only natural to want to preserve their beauty. Yes, it is possible to purchase silk flowers, but they are subpar replicas of the real thing. Most people prefer natural flowers to fake. Drying flowers with silica gel is a way to preserve the blooms’ natural beauty for years.

The Tradition of Drying Flowers

Silica Gel Beads

The method of drying flowers has been around for centuries. However, historically the process was accomplished by hanging the flowers upside down in a dry, airy place to dehydrate naturally. This drying process would take approximately two to three weeks to effectively dry the bundle if there was no significant humidity in the air. In humid regions, the flowers would often mould if there was no ventilation or air circulation.

What is Flower Silica Gel?

Silica Gel is silicon dioxide (SiO2) synthesised to create a highly porous granule that absorbs moisture effectively. Often silica gel bags are placed in bottles of medication or vitamins to absorb the moisture. Commonly silica gel bags found in food products decrease the likelihood of mould and extend the shelf life. Silica gel bags are also placed in electronic boxes to absorb excess moisture or condensation, damaging the electrical components. Flower silica gel is the same gel used in all the above applications. The harmless silica gel granules boast millions of microscopic pores that absorb and hold the moisture from the flowers and the atmospheric humidity to accelerate the drying process.

Where to buy Silica Gel?

To dry flowers using silica gel to remove the moisture out of the flowers and the surrounding air. The desiccants bags are often found in food, electronics, and various items. Another alternative would be to use bulk silica gel to use for flower drying.

Color Changing Silica Gel

A regular flower drying silica gel made up of small blue and white silica beads effectively absorb moisture. The blue silica beads turn pink after they become completely saturated with moisture. If the drying process is not complete, remove the water-laden silica gel beads and replace them with new ones or recharge the existing beads to remove the moisture.

How to Dry Flowers Using Silica Gel Beads

Here is a step-by-step guide on how to dry flowers using silica gel beads.

  1. Silica Gel BeadsFind a container that is narrow with a lid. Ideally, place the flower in an upright position within the container and then close the lid. For a single flower such as a rosebud, only a small container is required, but a larger volume of flowers will need a container of far greater size. Ideally, the container should be airtight when sealed. If drying long-stemmed flowers in a bouquet, lay them in a flat container with a lid in a flat position to dry instead of positioning them upright.
  2. Snip the flower’s stem using a pair of pruning shears to create a fresh cut to accelerate the drying process.
  3. Place the flower into the container in an upright position. It is possible to dry more than one flower at a time with a large enough container.
  4. Fill the container with silica gel beads until the flower is covered halfway.
  5. Position the flower one last time in the position that is required. Arrange the petals accordingly.
  6. Apply more silica gel beads around the flower until the container is full and the flower encased in the beads.
  7. Place the lid on the counter and make sure it is airtight.
  8. Store the container in a safe location until the drying process is complete.
  9. When complete, remove flowers from the silica gel and use a light paintbrush to brush off any stray silica beads that might adhere to the delicate petals or leaves.

How Long Does the Flower Drying Process Take with Silica Gel Beads?

The flower drying process time with silica gel beads varies and depends on the type of flower. A delicate flower such as a daisy may dry in only four or five days, but a full, water-laden flower such as a rose will take ten days to two weeks to successfully dry. Some flowers or bouquets can take up to eight weeks to dry successfully.

Checking on the Drying Process

Carefully remove some of the silica gel beads to check on the drying process and see if the flower is ready to remove or not. If it still feels heavy and water-logged, replace the silica gel beads and wait longer.

Recharging the Silica Gel Beads

Recharge silica gel beads for later use by heating the absorbers. Heat them on medium-high for about five minutes to remove the moisture buildup. Once recharged- the colours will return to blue from the pink hue.

Taking Care of Dried Flowers

Flowers that have undergone drying are incredibly fragile. Many people opt to place them into a shadowbox for safekeeping. Please put them in a safe place away from pets and other things that might inadvertently bump them.

Without a doubt, drying flowers with silica gel beads is a great way to preserve their beauty and hold onto memories. It is also inexpensive, fun, and straightforward.
