Cob: clarification on Quick lime vs hydrate

[Charmaine R Taylor]

Darel, all quick or hot lime is is slaked in water before it can be
used, only one commercial water purificaiton process used quicklime
straight and even then it is mixed with water right from the slake tank
into the next system within  2 minutes mix time.

What you may want to do is refer to the lime as "lime putty" ( into a
can right after proper slaking and left to age)  or dry hydrate which is
whent he water has been given off after slaking, it is then bagged for
sale.

Referring to "aged slaked lime" is like referring to eating "baked
bread". .no one eats raw dough and calls it bread it is understood that
bread is baked
- and quick lime is not used as quick lime..it is always mixed into
water for processing  as wet putty or  dry lime hydrate. make sense?

and I hear many folks can get quick lime...for their own slaking,
mostly NM or AZ/TX areas but I have not been able to ever get any...so,
who knows?

The ASTM  standards for lime are so high and complex in the US that
buying  commercially made lime is the best chance for good quality, and
there are many types avail. The housing industry just isn't the big
user, it's a miniscule market, and masons/plasterers  who knew how to
mix and use all limes are virtually gone with the horse and buggy.
