I build Austrian Kachelofen. I learned my craft in Austria where we always
used slaked lime mortar. Great stuff that comes in a plastic bag all wet
and kind of crisco like in consistancy. The advantages to using slaked lime
are many, but number one is that it is very flexible when cured. Since my
stoves are constantly heating and cooling, flexability is an important
factor. I know that one can produce slaked lime from type N lime, but I am
unable to find any. My local cement supplier has tried, I have tried the
internet, but to no avail. Do any of you know where to find either type N
lime, or prepackaged slaked lime

You might try a drugstore. I got some there once, I think it was the same as calcium carbonate but Im not sure. I only needed a small amount but they might be able to give you a source for larger amounts.
*Is there a difference between lime putty and slaked lime? My offhand impression is that slaked lime is dried limed putty, i.e., hydrated lime. See Mersey Lime Exporters.Try (again) an internet search engine; I cursorily used Apple's Sherlock meta-engine. You have to be tricky with the search parameters sometimes. Start with http://www.yahoo.com
*Scott,Take ordinary Ag lime and slake it yourself. Put it into a large container and add water..this will generate a lot of heat...it can be left in the container ( say a 44 gallon drum ) and used at leisure...beware of lumps that havent slaked as they will "blow" your mix later. It is best to force it through a sieve of some sort prior to use.Mark
*Mark,So what is the "type" of lime used for Ag. I have thought that that would be the way of getting my slaked lime is to produce it myself from powder. Have you done this and used the finished product for mortar? How did it work? thank you for your reply.Scot
*Andrew,Thanks for the link. judging from the telephone number, those guys are in Europe somewhere. I also use the Sherlock and will try again.Thanks alot.Scott
*Scott, I live in the other hemisphere..we have used bagged Ag lime and slaked it ourselves...the longer you can leave it the better it is. A lot of the colleges here use it for their bricklaying and tiling apprentices as it has the same consistency as a good mortar but has the advantage of being able to be reused ( the sand or loam that is ). Try your local Polytech or trade school..they may be able to help out.
*Yes, British I think. It takes some effort to narrow the search, I just grabbed a hit from the top ten that looked good. Sherlock tends to be pretty bright, but the user interface is dumbed-down too much. Looking forward to trying Sherlock II. (And I like to plug Apple products.)Fortunately for your search, we don't use the wood "slake" a whole lot in English! In fact, that may be your problem -- the commercial term for slaked lime in the States is something else ("lime putty"?).Try this glossary. (A check with "askjeeves" also gave me a recipe for key lime pie. What we need is artificial intelligence search engines that understand what you mean, not just the words you say.)
