I could make the statement, its not a claim, because somebody previously
wrote that they were confused by the phrase.

Sorry Charmaine, I wrote no such messages to the list with this content
or anything about time wasting.  You owe me an apology there.

It gets very hot and yes, people need to know what they're doing.
I presume this is why in America you can only get pre-slaked lime.

They use this method to heat food in take out lunches. But, the content
and containers
 are made for it.

Lime can be made by firing limestones or oyster shells.  Some people do
it for fun in a little burner.  Doesn't produce realy pure lime though. 
You'd need about 800 to 900 Celcius for that.
