I made my version today using raw sugar instead of honey. When the prohibited words were said and all was dissolved, the lye concentration was 36%. That included enough water to dissolve the EDTA that I used instead of my usual sodium citrate in an attempt to keep the lye concentration as high as possible. @KiwiMoose I borrowed your idea and added AC to the batch. To keep things exciting I almost forgot the pumice (duh) and ended up dumping the batter back in the bowl to add it. There were some bubbles by the time it was finally settled in the mold, but it looked good.
