So I'm doing my first EH conversion to test base. As per instruction I made a saturated solution of of NaOH using Rooto crystals of 100% lye and water and added it to my mix of heet and dissolved pellets. It instantly turned bright yellow. Then the solution separated with what I am assuming is the lye settling to the bottom and a now brownish, thick liquid on top. None of the instructions I read over mentioned any of these effects, so now I think I must have screwed something up. Is this normal?
