handle on pots, rivets & strength

They are probably aluminum with a shear strength of around 300 pounds

Please don't confuse him with facts. He's failed to realize that a chemical process is going to happen when aluminum is in contact with tomato acids (and sped up by heat.) It will be beneficial to our economy if he goes out and buys more product because he is afraid to use what he owns.

Egads!

Which has to do with leakproof bonding at the margins.

Mercury amalgams have been used by jewelers for thousands of years. I doubt they can be patented.
Amalgam fillings are becoming less popular not because of toxicity, but because porcelain-acrylic composites don't fall out after 20 years.

Interesting. You would not happen to know if there is any European country that seldom if ever uses aluminum cookware? Then we can compare the disease rate of that nation against others. It would not prove that aluminum is the cause of some major disease, or, as I suspect the facilitator of a major disease. Trouble is that aluminum is so widespread in cookware that we cannot have an isolated study. And most of these brain diseases take 20 or 30 years to unfold.
Iron, whether elemental or stainless steel or other iron alloys should not be a problem for human bodies but the fact that elemental-aluminum is only a modern day substance for which our animal-evolutionary past was never exposed to, that my instinct tells me it is not as safe healthwise as iron.
It was crazy to use lead vessels or pipes or containers in our past history. My sense of the situation is that it is mildly crazy to use aluminum as cookware, even though no medical proof is in. But since it is so widespread that even if the proof exists of a link to disease, that such information would be suppressed by a very large crowd of people with their various vested interests.
We have moved from nicotine to asbestos. Will we now move on to aluminum?

It has been my experience that the composites last about 1/2 as long as the mercury-amalgam and they also easily become stained. But perhaps the technology has improved.
I never get mercury in my teeth anymore. Simply because I know mercury is dangerous and stays forever inside your body. I get the composite or the gold fillings.
I like the composites for another reason: in that in winter when drinking warm tea can sometimes send my nerve in the tooth into the outer limits of pain. Which never happens to a composite filling.
I suppose dentists love the art of putting in mercury, perhaps it is so much easier than the composites and that is the reason why mercury fillings still exist when they should have been discontinued some 10 years ago when composite technology caught up.
Another thing I would like to see the EPA and world health organization bann is lead in sports of bullets and fishing gear. We spread lead all over land and soil when we really do not need to. I would like to see steel or copper or zinc replaced in all bullets and fishing gear. Here again is an example of where the few, stubborn political powers allow the pollution of the planet when all it takes is a simple legislation by the wise. Although I do hear that some states ban fishing gear of lead because their lakes have too much lead in them.
P.S. it is interesting to note how the EPA acts in different presidency's. In a president who cares about the environment then laws banning lead are made. But in presidents how give a hoot about the environment then their EPA's have persons who defend the "old ways of doing things" and attack the environmental people.

the animal MAY be poisened.
If the receptive and assertive forms of prion come in contact in single molecule quantity at appropriate temperature they MAY transfer orientation.
If a quantity of receptive prior in a susceptible animal's tissue is exposed to a quantity (a very small quantity) of assertive prion from either an infected animal or an animal that naturally uses the assertive form of prior, transfer of orientation is nearly orientation, nearly always resulting in death, since animal life is at temperature, and kinetics are favorable, granted only diffusion and time.

Well if your worried about Al in cook ware then you should watch what you eat. Al is used as a preservative in foods even baby formula. They listed the Al content of many of the popular brands a few years ago and the ppm would surprise you. If you don't like Al cooking then don't go to Italy they still want those Al coffee pots.
Ever wonder where or who ate the Teflon missing from the bottom of that frying pan or what is released from the bonding agents used to stick it to the Al or what ever the pan or pot is made of.
Lots of dentist will never emit the filling issue the insurance cost would go thorough the roof. There has to be something to it when they remove them they have to dispose of the used filling as hazardous waste and I don't think they can even let the rinse water go down the drain. They say they've been used for years with no problems and the people that claim it effects them it's in their mind, guess they don't believe that some people are reactions to bees, peanut butter and yes some react to metals.
orientation.

Excuse me but don't MANY minerals and rocks (including ***___CLAY___***) contain Al? Al is not a rare element, it's only problematic to reduce from its compounds.

According to my dentist, it's because the material acts very similarly to natural enamel. Coefficient of expansion is nearly identical, so composites won't work themselves loose under normal stresses.

It's changed. I had implants done two years ago. Same material, just more of it. Prosthetician recommended that if I wanted my teeth whitened, it should be done prior to ordering the crowns. Natural tooth enamel will yellow. Composite won't. Whitening will make otherwise perfectly matched implants obvious.
I wonder if you wouldn't absorb more from natural sources?
You can also chew on foil without shocking yourself.
Or they're conservative, and prefer to stick with older, proven techniques.
What's the cost difference between amalgam and composite?

FYI - Lead shot for hunting waterfowl has been banned for some years already. It was only considered dangerous enough for this to be done because the birds were ingesting the lead shot instead of pebbles for grinding food in their gizzards.
You drastically overrate the dangers of mercury amalgams and metallic lead. Both metals are very unreactive and it is only their organic complexes which are dangerous. Mercurochrome is still offered as an antiseptic. In the case of mercury amalgum the mercury is so strongly bonded to the silver that there is little exposure of the patient to the mercury metal itself. The image of the EPA chaps in isolation suits chasing the residents out of the condo built in the old GE plant in N. J. where they had been living for years without harm is a great illustration of the nonsense that bureaucrats are capable of creating to justify their continued existance. Find something important to worry about.
Then whats the nucleus?

Yeah, but I think you've already been outvoted on that matter. I recall voting for both lead and durian juice to be in all your cookware when the petition came around.
As far as whether your pot contains lead, here's a suggestion: IF IT SURVIVES BEING HEATED, IT AIN'T LEAD, DOPE. Lead melts at a temperature that can be easily produced in your kitchen. Try holding a match to your pot for several minutes and if your fingers burn instead of the pot, we'll both be happy.
It depends. Precisely how many hundreds of pounds of food does your pot need to contain?
"black scum"... that phrase seems oddly familiar...
Oh, I get it! The reason Kurt Stocklmeir's been posting about different stuff lately is that the original Kurt Stocklmeir is now posting as "Archimedes Plutonium".
Kurt, please give Archie back his iMac. And I hope you didn't get your slimey fingerprints all over it or he'll have to soak it in the sink with his pots and pans.
As to safety, you might want to try to remember what sorts of pots they allowed you to handle when you worked at Dartmouth. I bet they only gave you round ones and didn't let you wash any of those brownie pans with the sharp corners.
Naah, we're not ready for something so far-out. Let's just hear some more about your idea to land the Moon on Iowa and drive it around the country to escape the solar flares caused by terrorists turning Jupiter to salt and dropping it into the Sun or whatever else your simple plan is this week.
Um, Arch, the pressure cooker was invented long before you washed your first pot.
The Universe isn't just dots! It's got pots in it too!
