[Cob] Lime

[Amanda Peck]

It sure would be nice to have that much choice.

Around here, this county, and the one to the south, don't carry hydrated 
lime at all.  The one to the north does, though.  So unless I want to buy 
half a truck load and/or pay shipping I take what I can get.  It's 
reasonably white, and works pretty well.  And is nice after it soaks for a 
good long time.

When I spent the summer in a Mexican Indian village, people bought hydrated 
lime--it came in on horseback--in bags marked "not for food use."  Which of 
course was what they used it for--soaking corn to grind for tortillas.

Charmaine's right by the way--Rubbermaid tubs work a lot better than olive 
barrels.  Although on one I've had to bungee cord the lid on.

It will be at least a couple years before we'll have a need for it,  but I 
want to get a jump on soaking some lime for future plasters,  etc.  I was at 
a cob workshop this past week and was talking with the  instructor for a 
plastering workshop that was following and he  mentioned/recommended 
Graymont hydrated lime.  I didn't take note of  the specifics, and see on 
their website that they produce a few  different hydrated limes-
     * High Calcium Hydrated Lime
     * Dolomitic Hydrate Type N
     * Dolomitic Hydrate Type S
     * Dolomitic Hydrate Type SA
     * Niagara Lime Putty
     * Food Grade Hydrate
     * Lubricant Additive Hydrate
