[QUOTE="hotwheelsearl, post: 7912166, member: 75143"]Great questions. Sodium hydroxide is also known as Lye. You want the stuff that says "crystals of 100% household lye" or something like that. Here in my neck of the woods, Home Depot and Lowe's don't have it; you need to go to Ace or one of those more speciality shops to find it. Can also find on ebay, search "lye." You just mix it with water. It gets VERY HOT, and will let of fumes that make your throat hurt, so best to do it outside. It won't blow up but it will make the cup/container very hot. Best to use a glass jar; I have an old pickle jar that works for me. I sort of eyeball it, I often put maybe 2 tbsp per 8 ounces, more or less, i just sort of shake it into the jar and put some water in. Best practice is to neutralize it when done - I pour in a bunch of vinegar to neutralize the base, and then dump it down the sink. Be careful, it will cause chemical burns pretty readily. I've never had great results with electrolysis; then again I have no idea if I did it right. I fine lye much simpler and more effective. Good luck!
