I loathe buying lye. Really I do.
The only lye you can get around here is at Home Hardware in 3 kg jars --- it's huge. A lot of stores have stopped selling it in pure form due to the fact it's the main chemical components used in making methamphetamines.
Without fail, I always get this sideways glance when I'm carting this huge jar of lye around. I'm making soap with it, people...really!
