at least i concurr with the 2nd page on this new interesting topic!
yes, asbestos, a mineral, a rock, forming fibrous strands, unlike mica, which forms flat sheets. it is the nature of these fibres that is the danger. the stuff itself is completely inert. its used because its a rock, it doesnt burn. (ok...sulfur is also a rock...shutup).
mica, talc, asbestos. all very similar in composition. more a matter of prevailing conditions at the time as to what will form..
the fibres in brake/clutch pads form tough grippy fibres embedded in a binder, that are resistant to heat. perfect.
it makes a good insulator. stick a lump of asbestos into a blender and you got some nice fibrous material just like cotton wool but tougher!
all this hoo haa about asbestos annoys me.
consider one friend, an old mechanic. from the days of blowing out brake drums with airlines...in big workshops with no dust extractors...
some of his old work colleagues have died from emphysemia or similar respiratory diseases. he smoked as well as breathing in just as much asbestos as those guys...his lungs are fine. his backs stuffed but!
some of his old colleagues have died from other, non asbestos related ailments too! amazing!
some people are affected, others arent. while it should be avoided, its not necessarily a bad thing. just its inappropriate useage and peoples ignorance, as usual...
now GM? genetically modified organisms? they are completly and utterly wrong. wrong. wrong. that they are allowed into our food system is one of the biggest blunders in human history. we'll find out one day i guess...
radioactive waste in china foundries? entirely plausible! nukes are humanities second biggest blunder, and just like all these cooking shows, noone ever contemplates the waste produced... sewerage disposal, uranium "23whatever it is" after its exhausted disposal... nah, just dig a deep hole, it will be fine...
would explain why it welds so badly!
