Is it just on the surface or can it be ground down to expose accurate color? Im guessing either incomplete wax elimination/ dirty wax or you used a cleaner and have some contamination from it.

I would agree. Your zirliner and thicknesses are correct, so I would look at your wax for contamination and your burnout for being complete or not (is your ring completely white or does it have some grey/black areas on it still).
