Silica gel where to find

Activated Carbon. Battery Acid Spill Kit Specs. Cargo Dry Pack. Ceramic Ball Bed Support. Clay Unit Pack. Desiccant Air Breathers. Gas Phase-Air Filtration Media. Humidity Indicator Cards. Molecular Sieve. OrganoClay Water Filtration Media. Silica Gel Desiccant. Fancier types of silica gel contain other chemicals that change colour when they are saturated with moisture. The silica gels work best when in a sealed container, and the beads themselves are in a breathable bag. But, in the case of the seaweed silica packet, the wrapping seemed to be plastic, which didn't seem right, so I put it in water.

The water and it did not seem to pass through to the silica. This makes me wonder how useful it really was.

I then repackaged seaweed into two resealable bags and had one with the silica gel and one without. A day later, they both seemed fine, so that did not really tell me much.

The experimental design needs work and time, if anyone would like to pursue that. If you totally immerse silica beads in water, they make a popping sound and some of them break apart. If a bottle of vitamins contained any moisture vapor and were cooled rapidly, the condensing moisture would ruin the pills.

You will find little silica gel packets in anything that would be affected by excess moisture or condensation. Silica gel is nearly harmless, which is why you find it in food products.

Silica, or silicon dioxide SiO2 , is the same material found in quartz. The gel form contains millions of tiny pores that can adsorb and hold moisture. Silica gel is essentially porous sand. Truthfully, silica gel is nontoxic. The biggest issue, according to the Illinois Poison Center, is choking on the packet itself. Since there can be confusion sometimes over what exactly is in the packet, the Arizona Poison and Drug Information Center recommends calling poison control if someone swallows a desiccant packet, just in case.
