cretinbob: miss diminutive: 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.

because this


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

Strong chemicals are environmental hazards, too. A nice green way to dispose of the dead only requires a few dermestid beetles:

Yes, mercury is a poison. People still defend it's use in vaccines against all reason. Funny, how they are conditioned to accept their children being injected with known poisons but think it's oh so awful in every other respect.


Small pox, diphtheria, tetanus, pertussis, polio, measles, mumps and rubella can kill you. The amount of mercury present in vaccines is less than you get if you eat fish and shellfish on a regular basis.

Good idea. We use both potassium and sodium hydroxide to degrease/ clean stainless steel and tile in a meat packing plant. Both have a ph around 12-16 depending on dilution and increasing the temp to over 500 degree F and increasing the pressure would easily dissolve several hundred pounds of organic tissue and fat in a few hours. Bonus would be clean, bleached bones to grind instead of burnt nasty. Only downside I can see is discharging into municipal sewers...they would need to lower the ph to near neutral with CO2 and dilute with lots of water plus get a certificate from the city to dump. Untreated hydroxides kill off lots of digester bugs in the sewer lagoon/PO municipal waste-water operators.

And, this being Fark, I expect a bunch of bad chemistry puns and caustic comments.
