Letter Re: An Inexpensive Source for Bulk Silica Gel Desiccant
Hi, James
There is always a need for desiccants for various uses, be it food storage, caching,
or other projects. Most who need such things already have a favorite supplier,
but I'll make another recommendation for the sake of saving a few bucks. Any
local grocer, pet supply dealer or Big Box store carries silica-gel cat litter
in amounts from 3 to 30 pounds: Tidy Cats Crystals is one such product,
though there are many. A rounded tablespoon place in a square of mesh fabric
purchased in a craft/hobby department (where it can be bought by the yard--think
about the bird seed packets at weddings) and securely tied [or sewn shut] will
work well when
placed in the desired container; depending on the need, they can also be spooned
directly into the bottom of the vessel. Note that I'm suggesting the clear-blue "Crystals-only" type
which are pure silica; one doesn't want the silicate-clay "Blend" which
is also offered.
Being silicate, they have
the potential for re-use by oven drying. Compared to the cost of individual
commercial [silica gel] packets, this is a bargain. Regards, - Billfour
JWR Replies: That is a great suggestion. Just beware of any
desiccant that has any additives, dyes, or scents. A perfumed desiccant would
be fine for
tool storage, but potentially a disaster for food storage.
