[papercreters] Help Indiana- finding hydrated lime

I was able to find a small 5lb bag of hydrated lime in the garden section
____________

HI this is a small bag indeed, if you can find a farm/feed store that
caters to people with horses, cattle, then you may find a 50 lb.
standard size bag. as long as it says hydrated or high calcium or
dolomitic (dolomite) lime then you are OK. cost about $10 a 50# bag

bringing up the more confusiing hydraulic lime- this is a nautral
lime- no longer available in the US sine the cement cos. bought up all
the natural mines. a hydraulic ( wayer loving ) lime has lay and
minerals in it, and will set up to limestone again when mixed with
water.. like Portland Cement does


the French and Israeli imports of Natural Hydraulic limes are very
pricey, since they mix in the SAND portion to the dry lime.

it was necessary as people goofed up the product, and blamed the
maker, so now they ship it, 3 times as heavy, but with the right sand
mix in it. the St Austier lime co, www.limes.us has a ton of info
on plastering and using lime in building, but it is spendy! you an
achieve a lot with regular HYDRATED lime- which cures by absorption of
air, not the water. clear as mud?

HYDRATED- can sit in water and stay soft for decades- called lime
putty when in water, add sand and now called plaster or mortar, or
render

HYDRAULIC- sets up fast when water is added- imported into US.

The ement companies add clay to lime to make commercially produced
cement, and owning the natural hydraulic lime mines was a smart move,
but took our natural lime off the market forever. I resent that.
