Barium Carbonate - Bed Side Reader
 

I just finished reading the "bullseye mixture" in the 2nd Machinists Bedside
Reader and am interested in trying the color case hardening formula
described.

It seems the author got a bit of cold feet later on about the use of barium
sulfate.

So the question is how dangerous is trying the method? What should one do
to minimise risk? I see Skylighter has it at reasonable prices.

Thanks,

Wes

Sorry, I ment barium carbonate.

DANGER! MAY BE FATAL IF SWALLOWED. HARMFUL IF INHALED. MAY CAUSE
IRRITATION TO SKIN, EYES, AND RESPIRATORY TRACT. AFFECTS MUSCLES
(INCLUDING THE HEART), AND CENTRAL NERVOUS SYSTEM.

Health Rating: 3 - Severe (Poison)

In the event of a fire, wear full protective clothing and NIOSH-approved
self-contained breathing apparatus with full facepiece operated in the
pressure demand or other positive pressure mode.

Data from an MSDS is meant for folks dealing with industrial
quantities,
on a regular basis, in our current liability happy legal environment.

The same could be said for zinc, tin, or lead and we deal with those
metals on a regular basis.
Just take sensible precautions to avoid the dust or vapors.

Barium sulphate isn't poisonous, but the water-soluable barium salts
are quite poisonous.

Wes,
If you don't have it, get a copy of the "The Machinists THIRD Bedside
Reader". There is a follow-up article to the method given in "The
Bullseye Mixture" that tells how to do this sort of color casehardening
that avoids the use of most of the nastier chemicals.

If you have the book, you likely already know that, so feel free to
ignore the above.

You left out di-hydrogen oxide.

Is that the same as di-hydrogen monoxide?
I watched a program on the Moon the other day and they seem to think the
polar region may contain some of this di-hydrogen monoxide. Easily converted
to rocket fuel. Must be nasty stuff!!

I had some of that stuff when I was a kid (back when we could get the good
stuff, heh,) and I saw it dissolve some crystals BEFORE MY VERY EYES! It is
even more powerful when it is heated.

I mean really, if it can dissolve a crystal, it's got to be some NASTY stuff
indeed!

As others have pointed out, that's essentially the scary writeup
any chemical will have.

look up a MSDS on sodium chloride, even sucrose.

Not only that, it is THE green house gas, it causes more global warming
than all the CO2 man has ever created ;)

Barium carbonate is slightly soluble in water. In fact one can convert
barium sulfate to barium carbonate by boiling in a solution of sodium
carbonate. This procedure is used in analytical chemistry.

Barium carbonate dissolves in dilute hydrochloric acid (as do most
carbonates). If you ingest barium carbonate the acidity of the stomach
will convert the barium carbonate to soluble barium chloride and you
are in big trouble.

Barium carbonate is not particularly dangerous unless ingested. One
should wear breathing protection, since no heavy metal compound should be
allowed (voluntarily) to enter your body. One notable exception would be
barium sulfate, which is essentially inert in the pH range of body
fluids, and is used for contrast fluoroscopy. (a la "barium enema")

We use roughly 100lb of barium carbonate a month. We use nuisance dust
masks (p-95 rating), and enforce hand washing and clothing dust-off
before eating or smoking.

Cool. I'll wear a dust mask when handling, wash my hands and change my
clothes, a bit of cross ventilation (out doors). The MSDS looked similar
to lead for the most part and I've been casting lead for years. Good
hygiene rules will be applied. I'll wear the mask so my lungs don't glow.

I'll also look at the third machinist bedside reader formula using potasium
nitrate. Well after I get around to using the KNO3 I have on hand for its
original purchased purpose ( Don't tell homeland security )

Are you sure that it isn't Hydrogen Hydroxide (HOH)? The worst
parts of a strong acid and a strong base combined?

Usually that results in a salt. What do we call this one??? :-)

I used a couple coffee cans to make another batch of charcoal.

You can see the results of the gases being liberated from the wood. Makes a
