Jean’s tips

It’s im­por­tant to test the ph be­fore you use a batch of soap – if it’s higher than ph10, you risk it be­ing too harsh on your skin. Worse, if it’s too high (lye/ caus­tic soda is ph14) it in­di­cates you’ve made a mis­take and the caus­tic soda hasn’t pro­cessed prop­erly – this will badly burn your skin. It’s a good idea is to cut the soap open and mea­sure the ph in the mid­dle of the soap, to make sure it is pro­cessed prop­erly the whole way through the bar. Lye can sit in ‘pock­ets’ if it doesn’t mix. ph test­ing kits aren’t 100% ac­cu­rate, so err on the side of cau­tion if it tests high – leave your soap to cure longer.
