Use for lime dessicant?
 

I have a bunch of the little silica gel packets saved and dry and use
some from time to time. Just got a similar dessicant packet from the
nori we made sushi with, and it's labelled "Lime Dessicant/Do Not
Eat/Do Not Open/Your Children Will Die/blah/blah".

So wp says this stuff is (by now) calcium hydroxide. Any use in the
home shop? We eat a lot of sushi.

I dunno, but I do know you can re-dehydrate desiccant for reuse. Low
heat for a long time does the job.

Maybe put good tools in a ziplock baggy with a desiccant pack for long
term storage.

I use the hell out of it in ammo storage, along with electronic
storage of components.

I was once told by a “gun safety” advocate back in the Nineties
that he favored total civilian firearms confiscation.
Only the military and police should have weapons he averred and what did I think about that?

I began to give him a reasoned answer and he
cut me off with an abrupt, “Give me the short answer.”

I thought for a moment and said, “If you try to take our firearms we will kill you.”"

I was thinking more as a chemical than as a dessicant. I find myself
doing quite a bit of electrolytic derusting with the current batch of
projects and might want to do some small plating after I find out more
about it.

It could be only Quicklime, which you can buy cheaply in bulk.

Unlike silica gel you have to heat it hot enough to destroy the packet
to dry and reuse it.

"Once saturated with water, the gel can be regenerated by heating it
to 120 °C (250 °F) for two hours."

And it can be quite easy to overheat & destroy the silica gel packet,
guess how I know that........

This gives you low-cost, reasonably accurate high temperature
measurement in places where you can't use a stem or dial oven
thermometer:
http://www.amazon.com/TM-902C-Digita...ywords=tm-902c

Mine makes good contact with plugs from Omega. It shows only Celsius.
Personally I like air temperatures in F because I can relate to them,
but do all scientific measurement in metric.

Lime, as a dessicant, is effective, BUT it's pretty much the same
as cement (the stuff that comes in 80 lb sacks for a few bucks).
It isn't like the reversible dessicants of a chem lab (Drierite
is calcium sulphate).

Once lime has hydrated, nothing short of a hot oven will dry it quickly.
