I'm not CareBear but I think I can help. Basically, you taste the soap. You can wet your finger and rub it across the bar, and then put your finger on your tongue, or you can just touch your tongue to a sliver of soap (what I do). If it tastes like soap, you're fine. If it gives you a "zap" like putting a 9 volt battery on your tongue, you have free alkali in your soap and it's not ready to use yet. Edited because as usual....I can't type!
