Humidity color sensitive crystals?

Hi Fella's
I use crystals to remove moisture from inside my
storm windows. I rely on a hole breathing air from
the interior via barometric pressure variation, passing
through the crystals and it works very well.
The crystals turn pink when they are loaded with
moisture and blue when dried, (we use a micro-
wave oven to dry them).
Does anyone recall the chemical name and formula
for those crystals?
Regards
Ken

Actually, the crystals are likely to be something else, with a small
amount of cobalt chloride as an indicator. "Drierite" contains
calcium sulphate (with a small amount of CoCl2); you can also get
silica gel with the same indicator.

Thanks, these crystals are ~ 1-2 mm boxy shaped.
Could you guys provids a source where I could purchase
them?
Again Thanks
Ken

If you only need a small amount, you could buy
seaweed (called "nori") at an Oriental food store,
and a small packet of them is included with
the seaweed. I'd suggest the "Korean style"
seaweed, usually sold in packs of three containers
for about USD $1 per pack. That'll get you the
most cobalt-doped silia gel for your money.

Thanks guys.
For a bit of background, I bought a cottage in Muskoka
Ont, where temps are -20F in the winter, so I go for
upgrading the windows.

Well, the fuckin gov and window industry sell me these
dual pain (pane) jobs with a space of about 3/4", and
they iced up like shit.

So I built my own windows with double pane with a
spacing of ~5", however, they can't be sealed, cuz
of barometric pressure variation, as in the aneroid
barometric effect. Those windows worked great at
-40F, but some humidity appeared inside of them.

So what I did was to place the moisture absorbing
crystals via a tube that bleads the barometics off,
and the inner humidity is gone in about a week.

So I build a new house in BC canukistan, and install
similiar windows, but get this, the BI-guy (Building
Inspector guy) tells me that my installed windows
are NOT according to BC building code...duh, I try
to explain the superority of my window design.

Why the fuck a stunned govmonk orders it's workers
to make new homes retarded is what canuckistan is
all about.

Canuckistan is down the tubes!

What's happened is a degradation of leadership such
that a few morons acquired legal power via politics and
then think they are smarter than us.

Here is what we have to do, repeal seat belt laws!

STOP protecting people from themselves.
Put the responsibility onto the citizen OR the
citizen will NOT be able to be responsible.

The govmonks are attempting to remove the intent
of responsibility from the citizens, and by doing that,
declaring the citizens irresponsible.

But in truth, the opposite should occur.
In a true democracy the citizens are empowered to
maximize responsibity, what happened to that??

I think the building inspector doesn't have any choice, no leeway.
Can you go to the building department and get a variance? At least
here in California they can grant a variance from the code if you can
convince them that you're right.

It's my property and my home.
The BI-guy had some silly little ANSI spec that
for intent was far exceeded, IOW's the govmonks
want code compliance without understanding that
superior construction that exceeds code is ok.

The BC (Building Code) is a minimum standard,
to make sure a building is moderately safe, even
for the fukin morons.

That's the problem, our society is vectored to the
lowest common denomenator, the fuckin idiots,
and normal people are being fucked by that.

As I'll suggest, seat-belt laws, 2nd hand smoke
etc. is all paranoid shit. Seems everybody wants
to control everbody else just for power.

My self, I'd up-load power to the citizen, to
empower the individuals, and let them decide
how many donuts they'll eat per day before the
govmonks order a complete ban on food advertising,
as they did on smokin, drinkin and everything else.

Snow-skiing/snowmobile accidents cost more in
accidents than smoking ever did, but those said
activities have the auto/oil lobby putting bucks
up govmonks asses.

These days the cobalt(II) chloride indicator is considered a non-trivial
toxic and possible cancer risk (by inhalation). See for example:

http://en.wikipedia.org/wiki/Humidity_indicator_card

What do they do for invisible inks in kiddies spy toys now I wonder.

Deep separation double or triple glazing is sometimes used in the UK
more to stop external noise near busy airports than cold. Cold winter
here is seldom below -10C.

So long as you also stop treating the fuckwits that injure themselves so
badly by not wearing seatbelts I don't have a problem with that.

One was partially beheaded by his laminated windscreen at the end of our
road - not a pretty sight. Head went though it and on the whiplash
recoil the hole closes.

Provided that the citizens are not already so dumb as they seem to be.
The queues of clinically obese suckers waiting to gorge on vast amounts
of junk food tends to suggest that the public does need some protection
from rapacious corporations.

>> I think the building inspector doesn't have any choice, no leeway.

I can see it might be a problem in a listed building or area of historic
significance where new windows would have to look exactly right *and*
meet the building spec for insulation. But in the UK you would not have
any problems with building inspectors being bolshy about windows which
exceeded ISO stds being installed into an existing building.

New build would probably be a different kettle of fish altogether.

This seems to be your problem.

Given how you have stated your case here are you sure it wasn't that you
managed to get up his nose so much that he retaliated by enforcing the
precise letter rather than the spirit of the law.

Hi Mr. Brown, this post is only an acknowledgement.
I'd like to study more prior to posting.
