Powder. The price stated on the website is for 1kg of silica gel powder.

How it works

Thanks to its high levels of porosity (around 800 m²/g), silica gel powder has a high absorption capacity. Silica gel powder absorbs moisture and holds it inside, leaving no residues. Once the powder is saturated its weight increases in a 25% approximately. Once it is saturated it can be regenerated by exposing it to high temperatures (110⁰C for 1kg during 1 hour approx) in the oven (DO NOT put it in the microwave). The heat in the oven will allow the powder to release the moisture previously absorbed. This way the powder can be used several times, even though it loses part of its efficiency each time it is regenerated.


Silica gel powder is mainly used for drying and preserving flowers and bouquets. Place 2cm of silica gel powder in a container. Put the flowers or bouquet on top of the powder and cover the rest with more powder. Close the container as tight as possible. The process will take 2 or 3 days until they are completely dry.
