I doubt anyone would be able to tell. There's a lot of ponceing
about and mystecism with regard to lime, usually by various
bodies with vested interests in pushing their services.

The problem is that you don't know how long it has been hanging
around in the builders' merchants, and how much of the hydroxide
has turned to carbonate.

Not even by reading the date on the sack?
