There are 2 varieties of silica gel:

- One features an inherent color indicator, chromatic crystals of atomic number 27 chloride that act as wetness indicators. because the oxygen absorber begins to soak up wetness from the flowers embedded in it, the atomic number 27 chloride crystals can indicate this by turning lightweight blue so pink.

once the colloid has absorbed up to forty you look after its own weight in wetness, it'll now not be effective in removing wetness from flowers. At this time, atomic number 27 chloride crystals can indicate this state of supersaturation by turning white. The silica gel should then be reactivated before it maybe with success used once more. 

- the opposite variety of crystal is white. 

Both sorts are created from giant crystals that should be ground down. The silica gel that's factory-made expressly to be used in conserving flowers may be a sandy-type agent, nearly powdery in texture. 

Oxygen absorber may be bought from most hardware stores, garden centers, chemists, hobby or craft stores. They sell colloid underneath varied complete names and packages (Flower-Dri, Hazel Pearson, etc.), and also the best is to buy around to seek out an honest complete and appropriate value. 

To remove the wetness from silica gel and switch the crystals back to blue, place the colloid in associate degree previous however clean and dry shallow, kitchen appliance-proof dish (such as a lasagna casserole) associate degreed swing the dish within the oven at 250°F - for [*fr1] an hour or till the atomic number 27 chloride crystals come back to their original chromatic color. 

At this time, the oxygen absorber is prepared to be used once more or to be held on in airtight containers for cooling till required. As colloid can absorb wetness from the air similarly as from flowers buried in it, it's best to stay it lined in the least times.
