just want to say i was not saying not to do what he is doing. i think he was saying they gave him clean extruded price after doing this. i was just saying be careful. ive had lye burn little bubbles on my arm but i was being sloppy. its not hard to work w/ any harder than any other reactive substance but it can kind of do an explosion by adding water on top of it. its cheap to so if that was the only yard maybe i would do it. i would find another yard just because its just another headache to mess w/.

lye is still used to make soap. part of the process is making a water/lye solution and at those amounts the water jump from cold to 150-200 degrees w/in a minute of adding. nasty fumes also but that would be using a much stronger solution that what would be needed to make to this job. it is still sold in some stores for dumping in plumbing. a lot of people use it in making biofuel.
