Thanks Gunnvor for this additional info.

Can you also please tell us which cultures used this rottenstone in the 
Middle Ages and when? Do you know if this was simply ground limestone 
or whether it was heated before or after grinding, which I thought 
actually creates quicklime? Or is there more that has to be done to 
make this from limestone? Or maybe this had to be found in the 
"decomposed" state?

Thanks,
   Stefan
