They burned limestone--CaCo3-- at about 1000 degrees and released the CO2 giving CaO, quicklime.
The lime in sacks is hydrated calcium oxide and I don't think a stove even on cleaning cycle will dehydrate it.

I suppose it would be expensive, but you could take regular lime for adjusting pH in the soil and heat it so it decomposes and releases the CO2 and becomes CaO (it might work if you put a tin under the broiler of your oven or something. I still think that if you can get ahold of some Calcium Chloride (which they use in solution with water for ballast fluid in large farm tires.) We use it all the time in our organnic chemistry lab at college to soak up water from ethers, and alcohols we make in the lab. Swirl about a tablespoon around a 250 mL beaker until it is completely lumped up and keep adding it until the salt doesn't lump anymore. And I was reading earlier about using a lump of Sodium to "dry" alcohol. Doing that would give you Sodium ethoxide an not ethanol (of course, if that's what you're using to make biodiesel it works. But you risk blowing yourself to kingdom come in the process) JEFF <snip><snip><snip><snip><snip><snip> Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Please do NOT send "unsubscribe" messages to the list address.
