Derek,
Do you have suggestions for desiccant suppliers and water resistant containers or plastic bags?

Some friends of mine once to a steel plant thinking they could get the empty 100 lb cans. They just through the carbide in the mix can and all. It appears the steel can did not hurt the steel :) Gary Moss At 10:47 PM 8/23/2012, Mark Minton wrote: I agree. Calcium carbide is mainly used for production of acetylene for welding where it is not available in tanks. In the West that is increasingly rare. My guess is that carbide will soon cease to be available at reasonable cost. (It is already hazardous cargo.) Mark At 10:07 PM 8/23/2012, DONALD G.

What is the current practice to get the gas? >john Lyles No, calcium carbide was never a byproduct. It was, from the late 1800s, and still is, produced by reacting calcium carbonate and coke in electric furnaces. Its major use is still for making acetylene, but where petroleum and natural gas are plentiful, most acetylene today is derived from those instead. The Wikipedia article "calcium carbide" explains it. --Donald Please reply to mmin...@caver.net Permanent email address is mmin...@illinoisalumni.org --------------------------------------------------------------------- Visit our website: http://texascavers.com <http://texascavers.com/> To unsubscribe, e-mail: texascavers-unsubscr...@texascavers.com For additional commands, e-mail: texascavers-h...@texascavers.com
