I've been working(demo/new const/etc) at an old food refinery. One of the things they did here was burn their own limestone to create Calcium
Hydroxide. They also used sulphur, and used coal to fire everything. I have collected just from pockets we have uncovered. About 200lbs of pure
Sulphur, 50 lbs of Coal, and there is more calcium oxide(hydroxide?) chunks than you could imagine(although i was able to aquire a drum or so of the
refined 99.9% caoh from the site).
There is also some grey material which is think is part of the limestone production. It is very light and airy, reminds me of volcanic rock from a
garden, except its brittle and can be broke in half by hand. I find it to be very gritty, might be used as a pumice type catalyst holder.
Kind of a cool way to aquire for free, some rather cheap but worthwhile chemicals.
