Mercury from amalgam vaporised in crematoria is blamed for a proportion of airborne mercury emissions worldwide.

Interesting, I had no idea.

Why are we still using mercury fillings in the first place? The negative health effects are pretty well understood at this point.

Your dentist is behind the times. More and more are using composite fillings because they react more like teeth to heat than metals do.

For crowns your choices are usually gold, silver or porcalin. Do the silver crowns contain an amalgam?

I know mine are gold instead of porcalin since I tend to grind, and the gold is friendlier to the other teeth.

Because those health effects (from fillings, not mercury in general) are minimal, and because mercury is one of the few metals which is liquid near room temperature. You don't want a dentist pouring molten gold into your mouth.

And speaking of pointing and laughing at people, I'll join the submitter until someone can explain what the ridicule and the talk about (hydrogen) peroxide is about - especially since IIRC the pH of hydrogen peroxide solutions is lower than that of water which would make it an acid which in turn would make a pun about it and things being "pretty basic" a bit strange...

One would hope that a significant number of people being cremated are of the elderly persuasion, and received their fillings many years ago. These days, ceramics seem to be the norm, so eventually the problem will go away.

I know mine are gold instead of porcelain since I tend to grind, and the gold is friendlier to the other teeth.


Gold is the closest thing to enamel; it expands and contract the same way as enamel does, it can sculpt at mm width, as such it can be friendly to your other teeth and it will require less enamel removed from your receiving tooth. It is guaranteed for 25 years but most likely it will outlast you. Porcelain (metal fused or full porcelain) is guaranteed for only 5 years. However, aesthetically, full porcelain is better for frontal teeth (smile zone) and gold for your pre-molars and molars. Metal fused are usually not recommended as the metal seat can show up after a few years and leave a grayish tone to your tooth.

but again, with frontal gold crowns, you can start a rap career.

Hypothetically, if I wanted to dispose of an entire body I wouldn't choose a weak acid (in chemical terms) which forms an insoluble calcium salt. I'd go with something like piranha solution. Hypothetically.

From your linked article: "Piranha solution cleans by dissolving organic contaminants, and a large amount of contaminant will cause violent bubbling and a release of gas that can cause an explosion.[1]"

Which might be why Walt didn't go that route.

In a realistic sense, no it isn't.

1. HF is (relatively) hard to get, NaOH (or KOH) is easy to get
2. HF comes as a solution, hard to transport and store. NaOH (or KOH) comes as a dry powder.
3. Spill some NaOH on your hands and you'll say, "I feel slippery" maybe even "I feel a little itchy". Spill some HF on your hands and you'll say, "Owwww, this is the worst pain imaginable. Oh god make it stop".
4. NaOH is much easier to dispose of safely and without detecton

Caustic doesn't really work that way. As long as you take a few precautions (have a buffer solution or running water to rinse with), there is no reason that you can't quickly and relatively painlessly wash off a caustic spill. Worst case scenario, you get a few drops on you that you don't notice leaving a hole in your shirt and a local burn.

HF is a contact poison that pretty much instantly soaks into your skin. A few unnoticed drops can kill you.

From WIKI:
"Hydrofluoric acid is a highly corrosive liquid and is a contact poison. It should be handled with extreme care, beyond that accorded to other mineral acids. Owing to its low dissociation constant, HF as a neutral lipid-soluble molecule penetrates tissue more rapidly than typical mineral acids. Because of the ability of hydrofluoric acid to penetrate tissue, poisoning can occur readily through exposure of skin or eyes, or when inhaled or swallowed. Symptoms of exposure to hydrofluoric acid may not be immediately evident. HF interferes with nerve function, meaning that burns may not initially be painful. Accidental exposures can go unnoticed, delaying treatment and increasing the extent and seriousness of the injury.[8]

Once absorbed into blood through the skin, it reacts with blood calcium and may cause cardiac arrest. Burns with areas larger than 25 square inches (160 cm2) have the potential to cause serious systemic toxicity from interference with blood and tissue calcium levels.[9] In the body, hydrofluoric acid reacts with the ubiquitous biologically important ions Ca2+ and Mg2+. Formation of insoluble calcium fluoride is proposed as the etiology for both precipitous fall in serum calcium and the severe pain associated with tissue toxicity.[10] In some cases, exposures can lead to hypocalcemia. Thus, hydrofluoric acid exposure is often treated with calcium gluconate, a source of Ca2+ that sequesters the fluoride ions. HF chemical burns can be treated with a water wash and 2.5% calcium gluconate gel.[11][12][13] or special rinsing solutions.[14][15] However, because it is absorbed, medical treatment is necessary;[9] rinsing off is not enough. Intra-arterial infusions of calcium chloride have also shown great effectiveness in treating burns.[16]"
