We are all experimenting and learning about materials which are not researched well...this listserv enables us to share ideas freely. > Typically we don't slake our own lime here in the States, it is already > slaked, and hydrated, and is simply soaked in clean water before use.

I found it through a simple internet search, which first directed me to a chemical manufacturer, who referred me to a distributor, who then suggested I contact an end user, Simplot, just a few miles away. I bought 4 bags at $30 each. The distributor also suggested food processors, such as Kettle Foods, who use quick lime in making corn chips (!) Slaking quick lime is an exciting endeavor, and should be done carefully. I put the lime in a galvanized garbage can, then added water. This sputtered and gave of an nasty smell, and got so hot it burned the grass under the can. Kiko suggests filling the can with water, then adding the lime. However, we haven't tried this, so if anyone has done this with success, I'd like to know. BTW, I've been told you don't want to use "fresh slaked" lime...the longer slaked lime sits (lime putty), the better it will be for application. This is in contrast to the typical hydrated builders lime, which deteriorates in quality because it has been dried out after hydration.
